[Q] Diversity of roms/kernels - LG Optimus 2x

Hi,
Firstly, I don't want to sound unrespectful to developers. It is just a few complains but I admire the time each one spend for creating new roms. There are lots, lots of roms/kernels in the android development section. It's a complete jungle! For a non technical user, I find it really difficult to choose a rom because:
There are no standard table stating what is different with the other. The list described by each developer is not always clear. Especially when he or she sees "aroma", "CRT", "ram hack", "zipalign" without explication. Wouldn't one nice and small sentence be sufficient to explain these terms?
The issues for each rom are not tracked. I think there should be a tracking system like JIRA so that we can confirm if a bug is already described and if it is still present in future release.
It should be clear if a rom is based from stock or AOSP rom (edit: it's not always obvious).
There is no centralized topic explaining the differences. But I have seen there is topic listing roms.
To my mind, there should be in each rom description something like a history, a short sentence like "I have based this rom on this other rom because I feel it lacks this and that." (not always the case), instead of just throwing "hi, [screenshot], how to install this rom?". ^^
I believe what happen is that one user will check the 3 or 4 first roms and will get confused.
Generally speaking, I feel that when you read a rom description from the author, it is addressed to technical people. I think a centralized JIRA (each rom = one project) idea would be very helpful to compare but I don't know if it is easy to implement.
What do you think?

Actually always or it is baseed on stock or aosp or cyanogenmod it's pretty much in every thread i see. it's always described in the information they write.
and a centralized topic where is everything written well. it's for everybody else some like Lg stock ui and some like more clean android
Issue tracking jira i dont really understand i only know that developers are just wanting a catlog if there is a problem so they can see from what the problem is coming from or what it is related.
and that from a short sentence well. every rom misses something it's for everybody different and in almost all roms they are describing where it is based on and they have permission to use other work (the base) but some people are not asking it like the miui team who just took kowalski kernel without permission and they don't even give credit or something like that.
this post is just my opinion how i think it is

I do support the idea of asking the developers for more detailed info of their ROM / kernel features, however keep in mind that this is an Android development site - members are expected to have some level of knowledge and / or the will to learn stuff by themselves.
On the other hand, I've seen developers who care enough to spend time writing detailed documentation about their work and yet you'll find people asking questions or posting stuff without even reading the OP or using the search function. This obviously discourages the developer. Who will want to spend hours or even days writing how their stuff works or what are its main features if people won't take the time to read it?

I understand, but I don't ask for hours of well descriptions. One sum-up sentence and one link to a topic where other people has already spent the time should be enough. Example: an developer says "here are the 3 kernels [links]" and the only difference you can tell when looking at the links was "32rh", "16rh", "0rh". I had to guess that "rh" is ram hack and search for what it is. While with just "the ram hack is taking memory from GPU for the CPU", it's a clean and quick explanation. Otherwise people are bound to ask questions when they see this.
As for the JIRA system, it's just more obvious to see, for a newcomer:
how much issue a rom has at the moment
if a troubling issue important for you is described and prevent you from using the rom (so you don't waste time)
help the developer to see easyly what is wrong (instead of navigating through all the post)
help the developer by centralizing all the relevant information for one issue in one page, instead of having these spread everywhere

People requesting ROM advice

As a member for some time, I have seen many people post looking for advice on which ROM might best suit their needs.
Typically the response is anything from a small flame to a raging inferno. The most common response from the learned people here is for the OP to "try them all."
Well, I am finally fed up with those lame and rude responses. You see, there is absolutely nothing wrong with soliciting advice from those who have tried things and ergo have more knowledge and experience. That is why "user reviews" are so important. Think about it, have you ever asked a salesman about a product or do you just try them all? Do you eat everything on a menu, or do you ask the waiter what's good... what would best meet your needs? If you are a normal person, you ask if you have questions!
Also, there is much made about creating different threads asking for the proper advice. Well, the very nature of the request requires a new thread. Each OP might have a different set of preferences that are unique. To use the waiter example: "I don't like salty and greasy foods. I do however like light foods. What would you recommend?" You see how asking for advice has a certain individual and unique set of components?
Some people have told the OP to search and read up on all the ROMs. Well, unless your Einstein or have made ROMS your passion, no sane human can even begin to digest all the information. Some ROMS have hundreds of pages in their thread. One ROM might be a novel to itself. Some people simply don't have 40 hours to read up. Worse yet, those who do have the time, won't have a clue as to which ones to invest it in. Seriously, there are a LOT of ROMs.... with new ones being released almost daily. Unless you live here, you cannot learn about them all.
I think a fair solution would be for the fine people here to focus a bit more on creating a sticky thread of User reviews. However, it has be quite organized and kept current. There is nothing worse than sifting through a couple dozen pages in one ROM thread just to find out the bugs never were addressed in that release, rather the author issued a new separate release.
In conclusion, I think that until ROMs have a better system for Peer Review, which can be easily understood by visitors, people should lay off those seeking advice. Actually, people should be more than willing to be of help and not be so quick to blow the OP off. As for the ROM reviews, I suggest a new sub-forum for just that. It would go a long way to servicing all parties; those who seek advice, those who don't want to see it in these sub-forums, and those who want to help by giving reviews.
Well that is that.
Nice words and I partly applaud, however, you also have to see the other side. Let me reply by copying a user complain and the mod's reply out of his guest comment:

Ashley,
Thank you for your opinion. The Guidelines for the Kaiser Section were not invented by me solely and for no reason.
The reasons most Kaiser Mods discourage this type of thread, is these threads not only can create hard feelings between chefs but has been known to lead to all out flame wars
If you want to know peoples personal opinions on ROM, you are more than welcome to ask these questions in the ROM thread.
Also, the Kaiser forum is very active and placing peoples opinions of ROMs in the ROM Thread, where the chef can see and respond to such opinions, is more helpful to the community at large.
This guideline was not created to stop person opinions and speech. But to lead to a better organized Forum Section.
Thanks,
Jimmy McGee

As you see, it is not always easy to justify a thread, especially not if you're talking about a forum with the size of XDA Developers. If people think they want a review of the particular ROM, why not asking directly in the THREAD of that ROM?
"If people think they want a review of the particular ROM, why not asking directly in the THREAD of that ROM"
That only works if you want a review from a SINGLE ROM.
If chefs have that fragile of an ego....

As you now can see for yourself, this is where flaming begins - exactly the reason why threads like that are mostly not welcome!
I definitely think there's room for a single, stickied "ROM discussion" thread. People always have opinions, and it'd give people a place to vent them. The reason there's so many clutter-y "WHAT ROM?!" threads is because there's nowhere to ask that question, and new users have no real reason to understand how repetitive that question IS because all the threads get closed and deleted.
Simply telling them "you can't ask that!" makes it awfully tricky for new users, since they often don't even know WHAT they're looking for. By keeping a "ROM discussion" thread around, they might be able to at least get an idea of what people like about different ROMs. Heck, even if the place turns in to a pit of snarky vipers, it'll at least serve as an example of why people don't like ROM comparison threads!
The problems with just directing people to the ROM threads are thus:
1. Most ROM threads consist largely of bug reports or feature requests from long outdated versions of the ROM, so the information isn't really relevant.
2. Some (not all!) chefs are better at creating their ROMs than they are at describing them -- making it awfully hard to get an idea of what the author was "going for."
3. This makes it even LESS likely that some of the small, less popular ROMs will get noticed because the most popular, most updated threads are the ones that get bumped onto the first few pages.
4. ROM threads generally do not (and should not) contain information comparing different ROMs. This is, however, useful information -- if there's two ROMs claiming to be the "fastest and lightest," for example, users should be able to make their observations about those claims.
There's ALWAYS going to be a chance of getting people's hackles up and of some folks getting defensive of upset. At the same time, there's MORE chance for some chefs to get appreciation for what they've done, there will be a better starting point for folks new to this whole ROM business, and I think there's even a chance that the ROMs themselves will be improved because chefs might be able to keep their eyes on the rest of the "scene" better.
My 5 cents as a veteran noob.
First of all: This site is free to use. Lets keep it that way, by accepting the rules.
I think we have to realize, that this is not a service organization. This site is created by developers for developers.
Yes, it would be nice, if we could get answers quickly, but that is not the purpose of this site. Help - About: XDA
If you want to make this site a better place, Go Here!
A review-thread might be a great idea, but nothing is keeping you from creating another site for this!
So, you want a brand new ROM doing this, and this and that!
Well, so did I. And by trying different ROMs, I now realize, there are no shortcuts.
No matter how cool a ROM looks, there is always one thing about it you don't like.
One example: The new Manilla 3D looks incredible cool. Even if it is slow, I might still be using it, if it wasn't for one little thing that I just can't live with; The 3D "People" tab is very cool, but it is a pain to scroll through one contact at a time. I find the 2D version so much better.
You just have to try for yourself, what works for you and what don't.
Bottom line: To get the ROM that makes you most happy, you've got to make flashing your phone a hobby.
Read the stickies. Start flashing. Stay cool.
Happy hunting
I know this thread is closed, But I wanted to add to the statement of mine that was quoted earlier in this thread.
If you are going to get an objective Comparison or "Reviewed ROMs Thread" That would mean the reviewer would need to be unbiased. In order to do so they would have to flash EVERY version of EVERY ROM that was released. A difficult proposition at best.
I, like most people, will try a few and then Stick with one I find I like. There might be a better one that I haven't tried yet. But that's the fun of this Forum.
There was at one point a ROM Reviews thread. That thread was never closed. As it gave unbiased comparisons between ROMs. Something Impossible to get from just creating a thread saying "What's the Best?" Well ultimatly, "BEST" depends on your tastes.
The ROM review thread gave The features and bugs of a ROM and gave you a pretty clear pictures of the difference between the ROMs, All with the same "spin" from the same guy. By having the same "spin" from the same guy, you can grasp better which ROM is right for you. The effect of Me telling you what I like best and Junner Telling you their favorite is it has different "spin." Also, I may not have tried the ROM Junner recommended.
In the END the ROM Reviews thread died, because it was alot of work. And I believe we have even more ROMs available now!
So you can see why Best of ROM threads serve no purpose then to take up space. With the vast size of XDA's membership, you're not going to get a lot of worth out of a few vocal Fans of a certain chef's offerings.

Rom reviews

Hello all Chefs and Rom users, I wanted to know how would you like if someone started a thread or site where they do in depth reviews on roms,chefs,and apps for htc phones? Would you find this useful and would you be willing to post your roms on a site that does this? Would you be interested in paying for adverstisement? Would you like for a donation link to be placed in your review or section on the site? Rom users, how useful do you think this site will be? I am open to all comments and questions. Thank to all in advance.
I think that would be a great idea, especially for the people who arent sure which rom they want or what they want on a rom or the people that are new to this scene. Maybe the site could include a list of things that are included in the roms. Such as does it have the latest .net compact framwork and things like that. Also it could be broken down into which roms would be best for which versions of the rhodium. Like T-mobile, at&t, sprint, verizon. And there could be a rating system letting users rate the roms. Just a few ideas to throw at you.
Someone tried one of these threads here. I don't think it was useful at all.
My suggestion to noobs is this. Rather than learn about flashing different ROMs, learn how to quickly and efficiently backup and restore your device. Once you got it all down to about 15-30minutes, you can flash every single ROM out there and see for yourself which is right for you.

yeah i second this. The key thing about roms is that they differ in appeal for one person to the next. Most roms these days are nice and fast (certainly faster than stock) and so the additional factors may involve apps included, graphics and other features and although these are listed within the chefs thread as screenshots and lists, you only really know a rom is right for you once its in your hands and personally test-driven!
Agreed, it would be good to have an objective list of features of all current roms and comments of them in one place, however the info is already out there leaving the rest of the work up to the user!

i like it
as i have been flashing roms since the release of the original htc touch and have owned and flashed, hacked, and optimized just about every smartphone that has came out in america and some that havent, i consider myself a veteran and even i like to sometimes see how people feel about certain roms before trying them, i might be looking for a rom that does a specific thing very well and sometimes would like to know those strengths by reading about them first. thats just me, i dont think it would be a bad idea

I know what you mean. And I understand the intentions of everyone who starts one of these threads. But consider this:
-There are new ROM chefs popping up all the time.
-New releases of ROMs with multiple flavors are literally coming at a daily rate.
Who's going to keep track of all the chefs? Each chef may also release multiple ROMs. Who's going to keep track of all the ROM versions?
It's an impossible task, unless each chef voluntarily goes to a common thread to post about their own work. But frankly, I would rather the chef not waste their time doing that. I would rather them allocate their time to their ROM development.
Probably no one is going to argue that a review thread is a bad idea. It's a great idea in theory. But it just doesn't work in practice.
Why have a thread, wasn't he talking about a site akin to having a profile, like some kind of social networking site where each chef is regitered and releases their ROMS there?
ROMS can be reviewed, i.e. comments , requests etc

I am talking about a site,not really a social networking site, because that will just grow too huge and make it hard for some users to be able to get the info they are looking for. I am thinking more like a blog. Where you can search info and find different articles. There would be polls on roms. The rom may be reviewed with general info and people can leave comments. I just think it may be a way to narrow down this info for users to easily get to. Some are intimidated by huge sites. The site will have other info ,but will also lean more towards roms and chefs. The site would benefit rom users and chefs.

Reading from 40 to 400+ pages of a thread just to see what the rom is about isn't something I look forward to. I would like it if they were categorized. For example, search filters for all the roms that have sense 2.1 or all the roms that have 2.5, etc. Roms that are made specifically for a carrier would also be a nice filter. I also think a really good idea would be to make a program with the purpose of benchmarking a rom just to try and test the speed of how fast the rom really is. There are many more things that can be done. I think thewingster.com is a great example of this, but it can be taken to another level to make it much easier for users. There are many roms not posted on that site, but the popular ones are there.
I agree with some of the ideas here - sometimes it's just not feasible to wade through hundreds of pages ... For those who come here maybe once a week like me, this would be a good way of getting up to date quickly and maybe some of the n00b questions wouldn't happen as a result? (even I know how to get AT&T keyboard and my country doesn't have AT&T )
Maybe an extension of the current XDA wiki? And promote the wiki a bit more on the front page. The threads as they are in the forums would still serve the same basic purpose - feedback and debate etc.
The obvious question though is "who's gonna do it?" as the information would get outdated fast, and we can't expect the cooks to do it as they do enough already. And the people in the best position to do this (ie. the hardcore guys who come here every day) may not want to.
It's an interesting idea though.

Yeah absolutely, but there would have to be at least some form of moderation / approval / cleanup process otherwise you will just get 500 comments that are "HAW DO I GET MY NOKIA TO DO TAHT" or "I BRICKED MY PHOEN COS I DIDNT READ" or "D/Ling NOW KAKAKA!!!!11" etc. (much like some of the threads here) And then a team has to put all this in place, keep the version numbers up-to-date, put screenshots up, etc. A news feed available via RSS would be great Remember that most cooks have at least 4 different ROMs available for each device at a time. (Manila 2.1, 2.5, Titanium, AT&T dialer, WM6.5, WM6.5.1-3 etc)
Right now there must be 20 - 30 different ROMs available just for the TP2. Someone with some level of trust would need to be in charge. To quote an old phrase, "Garbage In, Garbage Out" And it would always have to be up-to-date otherwise there is no point.
Don't get me wrong it would be good to see something like this, it's a great idea. Kinda like what would happen if there was a train wreck involving the wiki and the forum haha but I think you may be underestimating the amount of work it will take.
I've often thought it would be better to have multiple threads per ROM, one for reviews, one for bugs, one for general chat, etc. Maybe even a sub-forum for each cook or each ROM.
I dunno I never said I had the answers Just throwing ideas round

Makes since thanks

Noob question: can you explain me ROMs, Kernels, Radio, Mods, etc ?

Hi all,
I'm quite new to this android stuff, and especially modding. And I have to tell that I feel a bit lost.
After a few days browsing this forum and other places on the internet, I think I know what a ROM and rooting are. But here I see things like kernels, radio, bootloaders... could someone explain me what those are and how they are related together? Or show me an url that explains all this.
Thanks a lot!

Im not real sure how to explain all this stuff in great detail but i will try and tell you all that i know. I think a kernel has to do with the drivers and things like that. A radio has to do with the everything that uses connections, i guess you would call it. Like your phone's network, wifi, bluetooth, etc. And for the bootloader i don't really know how to explain it but press and hold the power button and the trackball at the same time. thats the bootloader.
This should help some... http://forum.xda-developers.com/showthread.php?t=619153

http://forum.androidcentral.com/hacking/6037-general-rom-faq.html
If you’re new to the Android platform (don’t be bashful, all of us were not too long ago), you’ll see terms floating around the forums that you might not be familiar with. “ROM” is one of those terms. A ROM image is a data file that contains information used on a Read Only Memory chip. For our purposes, that means a complete system image of an Android device. Each Android device has it’s own ROM image that contains files and code needed to boot the device up and run Android on it. But this is only part of a ROM. A ROM also contains a GUI (graphical user interface), required and useful applications, support files for those applications and the kernel. Let’s have a look at the parts that make a ROM.

"ROM" is just a generic term for the software that makes up the OS, and a bit of a misnomer. This term could easily be changed to "OS sofware" or "system software". It does mean Read Only Memory, but ROM likely comes from that part of the system memory, since you dont want to be able to write over the system files (easily).

[Google]: android "what is a kernel"
http://androidforums.com/developer-101/62548-what-kernel.html
A kernel is basically the bridge between applications and the data processing at the hardware level. It serves as a level of abstraction for communication.

The easy answer is a kernel is the core of any operating system. DOS, Windows, UNIX, OS X and Linux all have some type of kernel. The implementations change but the basic concept remains the same. A kernel interfaces directly with the system’s hardware and is the lowest level of software. There are two types of kernels, micro-kernels and monolithic-kernels.

Good stuff Paul, it's refreshing to see someone go out of their way to help a newbie every once in a while
There are more polite ways to respond to this guy. Some people learn through interaction. I'm glad someone went out of their way to explain things to this guy. It's a shame how cut throat this community can be sometimes.
I agree, the attitude and lame jokes are really immature at times. Thanks paul for putting a lil effort and explaining few of the key points than cracking the usual radio is a fm/am joke here, the extreme nerdism almost kills me! lol.
As for the cutthroat and "nerdism" out there in this community, you have to remember, most of us that are regulars are ones that have been on this forum for a loooooooong while and not just in the Nexus One sections. I have migrated from WM to Android and see these posts time and time again.
There are Stickied "Noob" guilds galore, there is a search feature, there are TONS of resources out there for someone who puts in a MINIMAL effort can get this BASIC information.
When I first came here, I didn't just open a new post on "what is a ROM and ..." I read, I researched and when something wasn't clear and needed more information that wasn't out there, THEN I posted.
Those of us that may seem like we have an attitude aren't mean people, we don't expect everyone to come here with all the answers an NO questions, we just have an expectation that they at least put forth a LITTLE effort on figuring something out.
Paul did a great job in searching, but you have to wonder why the OP didn't even TRY and google anything or search here?
The impression I got is that it is not worth the OP's time to even try, so they put up a post asking these questions and expected the community to do all the work for them and compile some massive resource into a post that the OP most likely won't read and then start asking questions that were already answered in replies or links.
I have seen this happen time and time again on this board and others, so yeah, I am a bit of a jerk when someone puts forth no effort of their own.
Thanks a lot, Paul and the guys that helped
About me asking, and being new here... I DID search on this forum, but didn't find everything I needed. I used the search function, read the sticky threads, googled... After this, I still had questions, meaning that the information I got was not sufficient and that the additional information I was seeking wasn't accessible enough here. So that's why I asked.
If you don't like new people asking questions, but only expect new members to be experienced ones that will arrive with software/tricks/roms/etc "gifts" for you,you should reconsider your lifes. Maybe as sultans or something similar I agree with the remark about nerdy attitudes. Do you really think this is needed? If my topic is unwanted here, some people called moderators will lock or delete it, it seems it hasn't happened so far...
Back to the initial topic...
Well, maybe I did not make things clear enough. I'm not a complete computer noob. I know what a ROM is (not being specific to android devices), what an OS is, how to write a few lines of code, etc...
From what I understood, the bootloader can be see as the bios in a PC. It can execute a few tasks (diagnostics, rom flash, starting the OS...). The ROM contains the OS, software, config, etc...
As I said, what I don't really see is how all the things are related to each other. On this forum (and other places) I see a lot of alternative ROMs. I do understand what they are and their use. However I also see topics about kernels and radios, and that got me a bit lost. Aren't they already included in the ROMs?
Also, I'd like to learn a bit about how alternative ROMs are created. When additional features (applications?) are added to a ROM (features that were existing on other devices), is it "simply" the application files that from the other device that have been included to the ROM? When new features are added (not coming from other devices, like trackball led), how is that made? I assume it is added to the code somewhere, so is all the code available?
Thanks for helping
I'm going to move this thread to the Q&A section, and also clean up the noob bashing. Remember, not only is bashing discouraged throughout the entire site, but doing it in the Q&A section will likely earn you a short vacation from XDA.
Thanks,

What good is QA if question threads are closed

I started a new thread asking for ROM suggestions that met specific criteria... no where did i ask for a ROM without issues.
I got a few suggestions (most were "I like X" and not what i was after) and then the moderator locked the thread with the answer:
Your best bet is to try a few roms and stick with the one you like best. Most of the custom roms are good but to ask for something that has no issues when they are being built off a port and not Captivate source code is a bit of a stretch. There are no promises with custom roms, that is just the way it is.
So what good is the QA section if i Can't ask which ROMs support Exchange, BT, etc. I have tried a bunch that don't but now that there are 20 or so, there must be one that fits my needs.
I don't usually call people out, but closing a thread in Q/A when there is all kinds of other stuff going on is silly.
Do we have new rules for the Q/A section? Apparently soliciting advice on specifics is offensive to some. If it was closed because people can't answer the question - then you are punishing the OP.
I am a mod on other sites, and i am surprised this thread was closed with such impunity.
I guess this thread will be closed or deleted soon too. But thanks for reading.

1. All ROMs may not work the same on all hardware. So try them out to find out which suits u best.
2. If u have any issues, ask in the ROM specific thread preferably.
3. Read the ROM thread. Generally in the OP or in a post or two that follow, all the things included in the ROM are listed, along with anything that doesn't work. That should take care of u knowing if the ROM u r looking at has it or not.
Last but not the least, people may not always appreciate a question for which answer is easily search-able, or has been answered already many times, or are present in the ROM thread on page 1. Literally every rom today has the OP or the post following that details what all the ROM has, and where it fails.
I understand the op's concern as he was asking about some specific features which, although important to many users, are usually not addressed in the rom op.
You happen to be a casualty of the war against "which rom is best" posts.
Feel free to start a thread questioning when we will see gingerbread, or speculating on why we have yet to receive froyo though. Those appear much more frequently and are allowed to blossom into flame fests.

Best 2 sentences I've read in a long time.
As to your issue. I agree that you should be able to ask a legitimate question like that. You're not one of those asking which is fastest or which will get me higher quad scores. I'm thinking there's probably not a great deal of people who would have tested all those options either. Like myself, I have no use for Exchange or BT or even GPS for that matter. I can speak for the parts I use, which are the google apps and other things.
I would think that if you want the most complete ROM you should stay close to stock. Right now I think there are only 2 custom ROMs built from the stock Captivate ROM, Cognition and Firefly. Firefly does use an i9000 based kernel/modem, so I don't know if that affects the functionality you're looking for.
When in doubt, just keep loading all the ROMs to test them out.......j/k terrible idea.
Well sense you wanted to call someone out, I replied to you telling why I closed it and if you are a mod on another forum you should understand about asking for info that can be searched for and found with a little research. So lets look at your requirments for a rom that is built from a port and not Captivate Source code.
1. Stable-Most roms
2. Americanized-? the local settings can be set in each rom
3. No FFC stuff- not sure what FC issuses you are talking about.
4. Good sound/voice quality-Love the sound on mine mixed with the sppedmod kernel and vodoo sound app
5. BT support (voice dial would be nice - even with vlingo) 2.2
6. Exchange Support-2.2.1
7. Decent battery- that is all on what you consider decent battery, Mine lasts 12 hours and that is good battery for me
8. 2.2 or 2.2.1-most roms are built off of 2.2.1 there are some that are 2.2
9. Good data-Speeds is what I assume you mean, that is as much carrier as rom based
all this was found with a search, which I see more and more people are not using. This is not a make my phone cool forum. For lack of a better term this is an Research & development Forum.
Might want to Look at the FAQ in the threads that have them to see if you see any issues that is a deal breaker for you.
As for your other thread that is all you were gonna get was I like this this rom or I like that one. We all understand that custom roms are a give and take deal. You want the newest Unofficial stuff then you most be willing to deal with some issues that might come up. If you want something that works 100%, 100% of the time then I would stay stock as there are no promises with custom roms

I also think more should be done about all the questions in general. Move those to q&a and start handing out warnings. This is ridiculous.
At least I am not alone.
How many ROMs are there now? For me to search every single ROM thread (including all change logs) to see if a ROM meets my specific needs is silly.
I hate when people ask "how do I flash back to stock" and this is not one of those questions. I can't type this in the search field "Rom support for 1-10" and get any meaningful hit. And many ROMs link to alternate sites, and you have to view the features there - when they are all listed.... Some don't list email support until you go to the FAQ and it says email.apk was removed.
Again, I am not a newb looking for sympathy - I just want some equality in the heavy hammer. Next time I will title my thread "when will we see gingerbread" and all will be good.

So you think that If a question is posted that can be found with a simple search that a warning should be handed out?
I understand that the Captivate is for alot of people their first smartphone, and can be overwhelming, so new question threads for things that can be searched for are gonna happen.

I remove those threads when I see them come up. As silly as it might be that is what your gonna have to do. If you want a perfect rom your best bet is to learn to make it your self. Do you understand what "from a port" means. That means it was not made for our device and that there will be issues. The Dev try to fix them but like I said there is no 2.2 Captivate source code to build from so they do the best they can. Look I am not trying to come across rude but all these threads asking for this and that and "wtf this doesnt work" Is really starting to get on my last nerve. The only advice one can truly give is "Read, read and read some more to make sure you have all your bases covered."
I am not gonna argue the point any longer and will give this thread a few minutes for people to reply before I close it.
+1 Make your own, I did.
The time you flash all the rom's in the forum and test it out, you probably could of custom built your own to your specifications. So many roms out there, just not the flash freak like I was, too much time.

[HOW TO] [Q&A] How to best phrase a request to receive the most suitable answer?

Purpose
General Recommendations
When You Post in a Thread
Credits
Themes (at post #2)
Tutorials, Help Threads & Guides (at post #3)
Reports about Battery Life or Endurance (at post #4)
Possible WiFi Drops (at post #5)
Background: Following some threads in this forum I've pretty early realised that quite a few bug reports, requests and questions are raised without sufficient information to allow developers (dev), recognised contributors (RCs) or other members to easily provide solid answers and recommendations or a possible fix. Everybody should remember even the highly professional dev cannot read your mind.
Purpose: To provide some recommendations how to best phrase a request to receive the most suitable answer.
General recommendations:
Please read the XDA Forum Rules provided by @MikeChannon; from my personal point of view a definite MUST READ for everybody who intends to post on XDA or to contribute to this great site. Other MUST READ's I certainly recommend to everybody who wants to "breathe" what I believe the spirit of XDA is, are the following posts:
Forum Etiquette by @TheByteSmasher,
http://forum.xda-developers.com/showpost.php?p=16682226&postcount=2441 by @zelendel, and last but not least
http://forum.xda-developers.com/showpost.php?p=2031989&postcount=44 by @kyphur.
Do me the favour and really inhale what I just linked above!
Remember: Before you flash anything take a NANDROID backup or ensure you've an up-to-date one!
Before you post your issue or request, reboot at least once and try to replicate your problem. If it doesn't persist any longer the reboot might already have been the solution.
Read, read, and read again, read the OPs (first post of each thread) and scan the respective thread. Use the search function of XDA (in-thread search is so good). Also, you can use a web search. It means you have to read and study but I've no doubt you don't mind to do that for your device. With all this, you'll probably find your answer without having to post something.
A lot of OPs already contain hints how to solve commonly known issues, e.g. the [ROM][6.0.1][i9305 OFFICIAL] Resurrection Remix® M v5.7.3 OP by @rodman01 provides at the very end information and workarounds for random reboots during calls, camera crashes (see also post #43) or how to convert filesystem Ext4 to F2FS and vice versa.
You have first to know by yourself if your issue could be ROM or Kernel related. If you don't, post and see how it goes. Occasionally, the issue seems to be ROM or kernel related on the first glance but it isn't. For example, MMS sending or receiving issues are mostly related to somehow wrong or bad APN settings, or the baseband/modem isn't suitable for the respective local region or the desired carrier. A guide in regard to fixing of MMS issues is linked at post #3.
Before you post in a ROM development thread, be sure you do not run a custom kernel or Xposed (you should disable all Xposed modules and see if your issue still persists). Despite this, if you use a custom kernel or use Xposed and you're 100% sure it's ROM related, maybe you could post.
Last but not least: Don't ask what e.g. the best ROM or kernel is! All ROM, kernel, etc. available at xda are great but each one has its different specification, capabilities, pro's and con's. The best one for you is the one, which meets your desires and expectations.
When you post in a thread:
Post questions in Q&A forums or threads instead of DEV forums. But if you have a solid bug report (never reported before and fulfilling all the required criteria, check below) with all needed info, you can post in a DEV thread.
Don't make a dev, RC or anybody else to read your mind.
Don't have a dev, RC, or anybody else to make assumptions. As soon as an assumption fails the whole solution is going to become void.
Please post your issue or request by using the English language as mentioned in the XDA rules to allow everybody to understand the post and hopefully to contribute to or at least to learn out of it. Don't be afraid if English isn't your native tongue - that's certainly the case for most of the xda users. English isn't an issue here - as long as we all at least try to use this language. Even if your English skills aren't too developed just use simple wording; nobody is going to blame you; however, try to be as precise and unambiguous as possible.
Always run a logging tool to be able to augment your post by a log (logcat) file. Add the log as an attachment to your post or upload it on the cloud and paste the public link in your post. It doesn't matter, which logging tool you use but familiarise yourself with its use and where it saves the log. I'm e.g. using an app called "Catlog" that saves logs to the internal memory. Also you can use the MatLog app or use adb commands (HERE is a guide/tutorial)
If you're running Xposed uninstall it, and take the log again (while Xposed is running, the log even states that it's useless because of Xposed).
Take screenshots (quite often via buttons "Vol-" & "Pwr" or "Home" & "Pwr" depending on the ROM you use) or if more suitable a screen record (quite often via buttons "Vol+" & "Pwr") and attach them/it to your post. Before you take a screenshot or record, change your system language to English to allow everybody to understand the content of the screen. Some ROM provide these functionalities in the menu of the power button, too; however, they must be enable within the ROM settings.
Always provide exact and precise information about your issue. Write a description and, if possible, steps to reproduce.
Always provide exact and precise information about your device, the ROM, the kernel, your recovery, and specify the versions of the latter three. Occasionally information about your modem (or even bootloader) might also be helpful e.g. if you've problems with the RIL, mobile network or making phone calls. If you're on F2FS please mention.
If your issue or problem occurred immediately after you freshly flashed a ROM or kernel, please describe your installation procedure (clean, dirty, or describe when you wiped and/or formatted what). Please provide information, from which ROM or kernel you came.
If you have issues with anything from Google, specify the GApps version you flashed.
If you're using Xposed (not recommended when reporting bugs), please provide this important information including version and its developer as well as the modules you use.

Off topic comments are allowed as long they are generally related to the overall topic, are in the general interest of the followers of this thread and add value to the thread. The ultimate decision rests with me as the OP!
Themes
In addition to all statements in the OP, themes might be able to heavily influence system/ROM performance and behaviour; however, all pending on the used ROMs. Themes could mess things up on specific ROMs.
I personally got black screens on my GT-I9305 in the combination of a specific theme used, Resurrection Remix (MM) and Xposed. Switching to a different theme (PitchBlack | DarkRed CM13/12), which was developed by a Resurrection Remix dev (Altan KRK (westcrip)), solved the issue. Another RC experienced and reported to have had issues related to themes when he tested CM12.1 and CM13.
On the other hand, e.g. some Sammy stock based Android 4.4.4 ROMs (e.g. AMCHA ROM, N4 ELITE, TGP, etc) even don't have a theme engine, and shouldn't make the above mentioned trouble.
As said, it depends on the used ROM! But if you experience issues I suggest at least to consider your theme to be possibly involved. Guess it's pretty easy to switch to the stock design, probably to reboot, and to check if the issue persists. However, I like to stress again, it depends on the used ROM!
Thanks to @[I]Wood Man[/I] who first pointed me to the solution to my above mentioned issue, and second who doesn't get tired in providing hints for this thread!

A short story by me how I installed microG and related application on my GApps-free device is available here.
If any of the above information has been of help for you please hit the thanks button in the respective OP!
Reports about Battery Life or Endurance
If you observe abnormal battery performance, duration or life from your point of view, please take and check battery statistics yourself!
Please do NOT post anything beforehand (e.g. in the Q&A thread)!
From my personal point of view, a recommendable application to check battery stats is “BetterBatteryStats” but there a lot of similiar apps available. The OP of “BetterBatteryStats” provides you with good information about wakelocks and battery life in general, too.
Take your stats for some hours or even better a few days (and nights). Try to figure out if wakelocks persist that are triggered by apps or processes. If you are able to identify e.g. such an app, try first yourself if the issue gets fixed by de-installation of such an app. Think about getting in touch with the app's developer.
ONLY if it’s finally ROM or kernel related, post in Q&A section or dev section but observe these prerequisites:
Battery stats screenshots, AND logs, AND as many details as possible.
Good battery endurance paired with a "smooth" system behaviour seems to be priority number one for everybody for obvious reasons. However, regularly nobody clearly defines what a good battery endurance or life means. Is it the 24+ hrs, which satisfies the one, but 16 hrs already the other? Discussions about the battery seem to continue just knowing the type of device and probably the ROM but ignore the overall system and especially personal behaviour and preferences of the device's owner.
Besides ROM and kernel, a lot of different things are obviously effecting the battery:
How do you use your phone? Heavy load gaming? Screen permanently on while staring on "grimacebook" or "whogivesa..."?
What are the application running on the device, and which have permission for auto-start at boot or to stay awake? Which and how many applications do run in the background, and are eating fuel?
Age, capacity, and type of the battery.
Mobile data always ON or not.
WiFi always ON or not.
Cell network coverage and reception.
Screen brightness level.
Abnormal wakelocks triggered by crappy apps.
etc. etc. etc.
Prior to a decision for a specific tariff plan, analysis of the consumer behaviour in regard to number, duration, network of calls, text messages, and data consumption is desired. In turn, evaluation of battery life appears to require a similar approach by assessing the topics stated in the list above. Literally, at least I personally deem to be unable to advice anybody else but me how good battery life is or how to improve it.
It's somehow useless for different users to compare or ask for battery life between ROMs / Kernels since we all have different behaviours, different ways to configure the phone, and different apps installed.
For completeness, I'd like to mention there're multiple applications and Xposed modules around, which are supposed to extend endurance of a battery, e.g. Greenify, Amplify, or Power Nap in order just to mention a few. A web search might drag you to the ones that are best suited to you, and you always need to evaluate for yourself if they serve the advertised purpose and your requirements. Be also aware that some of them require the Xposed framework to function or for full functionality. Some guides are linked at post#3. If interested in privacy I suggest to thoroughly read the reviews of the respective tool, have its point or country of origin in mind, and search the web. Nearly all are requesting root privileges and/or use the Xposed framework i.e. are going to have more or less unlimited access to your device. Good news are many of them are open source, and at least the ones I mentioned above don't require access to the internet to function. I'd personally ensure that they mustn't pass the firewall (e.g. AFWall+ by @ukanth or NetGuard by Marcel Bokhorst (@M66B).

EDIT (2016-10-11): In this thread, I tried to explain how I did enhance the battery duration of my SGS 3 LTE (GT-I9305); however, maybe it's also suitable to other devices (I'm convinced it is).
Possible WiFi Drops
@Wood Man allowed me to quote him reagrding WiFi drops that occured to him several times. It never happened to me because my setup was (just by accident) always different; however, if WiFi drops occur to you please have a look below. The explanation is so reasonable and makes so much sense from my point of view. Thanks very much to Wood Man for sharing his knowledge.
Wood Man said:
...
Here is a feedback about an old issue I've reported about wifi drops: previous reports HERE and HERE.
I can say the problem is not the ROM neither the kernel. Everything is OK on your side rodman . The problem is just because I use Wi-Fi 2.4ghz and bluetooth at the same time. Since bluetooth uses the same 2.4 ghz frequency, it explains the problem: INTERFERENCES while streaming on both wifi and bluetooth at the same time!
It's a known and common issue with wireless devices. One culprit should be wifi or bluetooth drivers which not handle perfectly both connections at the same frequencies. Some devices well built, with good drivers, can handle this well AFAIK. It's never perfect because other sources of interferences exist.
One solution should be to use wifi 5ghz (if available on router, and device).
Another solution is to use better bluetooth devices which handle better bluetooth/wifi protocol, using the same frequency.

About drainage, I don't know. But could be...
The interferences happen only while streaming. I mean we can connect both wifi 2.4 and bluetooth at the same time without problem, the connection stays, but inteferences happen only when sound goes to audio bluetooth device.

Forgot to say that even if wifi 2.4 doesn't drop, the wifi transfer speed could very very slow in case of interferences with bluetooth streaming. (It's my case with my P9 Lite).

UPDATE (2017-05-26): Please find some additional, new information of @Wood Man at post #59:
...
I did a house moving recently and now I can use both Wifi 2,4 ghz and bluetooth at the same time without issues. The differences between my previous flat and my new one are:
1- A new router,
2- Less Wifi networks around me.
I bet point #2 above is the key because there are less interferences now in my flat ...

Actually not; I don't want to appear as a schoolmaster. That's the reason why I decided to create this thread.
I already asked FLooDW, but I'm also looking forward to your opinion?
Hi @noc.jfcbs,
Thanks for your thread, your time, your recent contributions and credits you gave to me
This is a good idea, I really hope a lot of members will read and apply your recommendations.
As you requested my opinion, I've done some modifications in your OP here below within the HIDE tags. Maybe some more adjustments will be necessary, I don't know yet.

@[I]FLooDW[/I], your suggestion is at least 10x better than my (let's call it) initial draft. Thank you very much for taking your time and having a look. ...actually it was much more than that. I did appreciate it.
OP is modified and waiting for further adjustments. Guess you can update your post now. CU

OK thanks for including my changes
My post is now edited.
Also, I've already added your thread in my signature
This is a very good thread, contribution and idea. The only problem to me is that it is in a secluded forum (quite) you may want to ask a moderator to move this to general forums or such.

Yes I was thinking quite the same. I'm not sure this thread is at the right place. But in another hand I think it could be a good idea to keep it in dev forum because the purpose is to advertise members to post the right way in dev threads. It could be discussed

Let me give you my 2cents:
The thread, no doubt, is in the wrong forum, but it should be pinned and given the highest priority. It is so effin useful.
The idea behind it is so good. Really. It makes me jealous. I will try and formulate some examples for @noc.jfcbs to add to the OP to further help newbies.

Well, good point
---------- Post added at 09:14 AM ---------- Previous post was at 08:41 AM ----------
However if we move this thread in Q&A section, I think it won't be read that much before newbies post in DEV forum... Even if it's pinned in Q&A section.
I really think it should be pinned in dev forum so newbies read before posting there, but it would also be inappropriate for dev forums...
Or it should go to general forum and pinned and linked to all dev forums. But then again if we link it some may not see (I'm guilty of this sometimes :silly: ) should I page a moderator? Or I think we should wait for noc.jfcbs to make his own decision

In any case we have to wait noc.jfcbs's point of view and then we'll ask a moderator.
@[I]FLooDW[/I], @limjh16: I've got to know both of you as very experienced and highly motivated Android enthusiasts in xda. Just looking at my joining date, I'm still a newbie on this site, and I personally rather take advice from guys with more experiences.
However, before I opened this thread I certainly thought of its right place, and I had all location you mentioned above under closer consideration but I finally decide to open the thread in the current forum for this reason: I remembered which the first forum was that I used when I initially came to xda. It wasn't any "general forum" or "Q&A" but the current one. I was in interested in ROM, kernel etc. for my specific device. Additionally, I thought if the thread doesn't fit here a mod is certainly going to move it to the right place.
Having followed your discussion I meanwhile believe the topic of this thread is much more generic and not at all related to a specific device and therefore should deserve a different location on xda. On the other hand, and that's a bit selfish, I'd like to support the forums and threads I'm used to mainly monitor by qualified posts of "newbies". Currently two hearts are beating in my breast; probably I'd rather be egoistic.

in that case, do you think it will be a good idea to include this in every rom thread? I will definitely quote this OP in all my rom, kernel etc threads with your permission. And we can always page for rodman
Allow me to make a suggestion, even or although it might be, that this couldn't be implemented in the forum system. Because of the reason that the 10 post rule seems to be cancelled (?), what do you think about, when ever a new member is willing to post a comment in a dev thread, he would get a pop up with a link to your, will say this post. Or in that pop up the message is already included. It might be a bit strict, but its mentioned without offense. I can understand, that most of the people and new users, want to get an answer soon or even at once, to their individual questions or problems and this without doing something of themselves. They want it presented or spoon feeded (@FLooDW ). And this also a matter of our current life style , in my opinion. But on the other hand, for example you and FLooDW and several others are taking their time to find solutions, to answer again and again and individually and user friendly. Porters or devs, if they are not also and additionally answer regularly in their threads, are spending their time with the roms they provide. So I think, if you/we request a bit time from the other users, that would not only be fair. It would also show a kind or certain respect to the time and effort other users are spending to support the others in which way ever....
Beside of that I personally would appreciate and prefer that this thread would be pinned here in the dev section...
Just my thoughts....
I'm just going to go ahead and ping @Trafalgar Square
I have an idea (not a very good / original one) that there is a pinned post in dev section that links to this thread. Not exactly this thread goes onto every forum, more of the pinned post redirects here
or if possible, rodman 's suggestion
