Roms based on froyo or gingerbread?
The discussion in the thread "30/Jun r1 (JFB) - MoDaCo Custom ROM for Samsung Galaxy S with Online Kitchen" is a bit confusing so I thought it best to make it a new topic to get it straight.
Will it be possible to make roms based on froyo, gingerbread or any other coming android version, before Samsung makes an update? As I understand psychoace it will be ”near impossible to get roms from other sources like Sense roms or Froyo”. Others are not so sure.
This is important as Samsung is known for its lack of interest in OS updates. Who knows if they will take gingerbread to GS? If they won't can it be done by the really smart guys?
I don't think even HTC will update there top line to V3 (ginger bread). Froyo is coming any way to GS in near future. Now ginger bread should be possible too as GS is power full enough to run. When? we should wait and see. Nexus just got updated to 2.2.
Will see how things go in future.
Samsung has released there kernel sources and there software sources. I haven't had a chance to look in to it deeply but if it has the code of the drivers etc.. it should be possible to merge (with some work obviously) sources and to compile froyo.

But don't those drivers only work with 2.1 and just simply won't with any version higher unless samsung releases new source and drivers for 2.2 and then 3.0. So if say samsung never releases anything any source/drivers that work with 3.0 then you would be out of luck to actually get everything to work.

That is true but if you have the full sources you are able to look what the differences are and maybe patch those by your self. Assume a wlan driver is using an function that has changed or is gone in 2.2, then you can try to patch that by finding the new one for it to work with. If you don't have the sources it's much harder to do those kind of things.
As I sad you have the sources so you can play by your self even if samsung does not do anything. It does not mean it's easy and it does not mean it can be done fast. But it does mean it could be done.

But the video drivers are already compiled. Can they be easily decompiled? It's not a source file if it's already compiled.

Can they be decompiled and made to work? Of course!
Will someone be motivated to do all this work? Unknown.
Besides drivers arent the only issue to getting a new version of Android on a phone. If you dont have source for any proprietary userland daemons/apps (like radio?) that communicate with the hardware you will be SOL on that as well.
MMMMMMMMM if we can do it for the G1 we can do it SGS...the question is when and how much work. The Galaxy S will be Samsung's flagship device for A YEAR so I'd hope to get Gingerbread...unless Samsung are really stupid. Especially with a lot of US launches, they'll be able to relaunch with Gingerbread as it comes is my hope.

Who told you that??? The source code of the GPU as well as every other coprocessor is there.
The two .o file that started this all fiasco are ok and you as long as the make file include them in the build they would work perfectly.
All they have inside is a simple elf code to tell the s3c*** to do whatever it needs to do. A source code wouldn't have been beneficial as it would have to be compiled differently for a different ARM instruction set .

But when you need drivers for 2.2 the source code would be optimal because these drivers are not going to work without some hacking.
They are going to work as they are non kernel bound ELF files.
Guys this isn't a driver ,if it was a kernel module ( or "driver" s you call it) it would have been a .ko file and had a slightly different structure ( use readelf on a kernel module and then on this to see the difference). So no matter what it is when can use the compiled version as it not kernel bound
From quick inspection it seems like the injection code for the s3c*** . so basically its there so the kernel could reference to it when the code tells it to do so . So Basicly all we have to do is put it in the proper place when building the kerne.
So please DON'T PANIC
well the TP2 just got 2.2 FroYo (2.1 has more working drivers ATM).. but if we have it, how would it be different for the SGS to get FroYo?
You need to remember that while other companies can update kernel quite easily ( all the work is done for them by the chip manufacturer and some member of the community ) this isn't possible here as this is a chip only used in one android/other linux platform device and the company making the device also make the chip.
So give them a few weeks to work on it

let's just say it will be the first time a non Samsung Rom has worked on a Samsung Android phone.

Not true.
Look here: http://forum.samdroid.net/f28/lkmod-v-2-5-1-based-jce-en-upd-03-30-a-336/
I see a custom ROM made for the i5700
Everything is possible.

Did I say custom rom? No i said specifically non samsung based roms on a samsung device. That custom rom is based off of a Samsung rom.
This is the closest we have got to a Hero rom on a Samsung device.

He couldn't get Rosie to boot so who knows what other problems he would of had after that (from the picture you can see he never got any network connection)
So there don't say I didn't give you any hope.
Froyo is offical. That's good, but we need to be looking past it to Gingerbread.
Froyo is announcedm confirmed, and now dated for the end of September, and that's great. But to me, that's not the question we need to be asking Samsung anymore, we need to be thinking past that.
The question people need to be asking Samsung, so we can get them on the record committed to it now, is will you release a Gingerbread update for the phone as long as the hardware is capable of supporting it. The OS is only 2-3 months from being unveiled if Google sticks to their time table, and if the rumors are true it'll be a much bigger overhaul than 2.1-2.2 is.
So unless we want our phones to be outdated before the end of the year, we need to start making a push as a community to get a commitment from Samsung to support not just the OS that was released 4 months ago, but also the much bigger one that's right around the corner.
2.2 is good.. proves everyone wrong who said "ooh its Samsung, of course they won't release Froyo."
but somehow, I doubt that samsung will somehow not upgrade SGS to 3.0. If they do, it might be a few months (at least) after everyone else gets it. The reason is, they could have new flagship devices out that they wanna push to the mass-markets, so putting gingerbread on that will boost the sales.
However, considering that they marketed the SGS so well, and have it well on its way, they might just put gingerbread on it
seriously, i see ads for SGS EVERYWHERE online.

I totally expect that my phone will be outdated by then. That's a consequence of the world we live in But then again, i'm a nihilist
Hi,
I'm trying to build cyanogenmod 6 (froyo) from sources on github for G1.
Sidenote. The reason I'm trying to do this is i'd like to modify kernel parameters. I'm trying to make the phone talk to external device using built in serial port. I can do it with my current CM6, but it looks like serial debugger engages and starts responding to the device and also steals some of the data being sent to phone.
To build I used instruction posted at cyanogen wiki "HTC Dream & Magic: Compile CyanogenMod (OS X)" which covers gingerbread but checked out froyo-stable branch at first. I know that gingerbread version stopped supporting G1 at some point last year.
Without much success even after fixing manifest to point to updated repo urls from kernel.org to googles repo etc. The problem is that apache-http seems incompatible with old sources and it is referenced by head.
I also tried froyo branch, but it doesn't build as well because something seem to be broken for dream_sapphire, and it is not present in the devices anymore.
I've tried searching for compilation errors, and general build questions/instructions here and on cyanogen's forum, but looks like CM6 is not very active these days.
Can someone point me into right direction where to search for relevant info on building it? Would getting a proper revision help or should I combine stuff from several branches to make it work?
I've already spent quite a lot of time figuring out how build is being configured and how things stitch together but without much progress on the actual build.
And with times required to sync a whole repo and build it, it is becoming frustrating.
Any help would be muchly appreciated!
Regards,
Oleg
It's dead.
I also wanted to make a cm6 rom, but I couldn't get anything to work.
I got the addresses all updated but it looks like a bunch of the files have completely dissappeared. You may be able to make it skip those, but then it may not work completely.
Go for AOSP?
Now that's a shame. I wanted to build CM because I'm familiar with it and the other thing is that they have reasonable instructions about building it. But at least I don't need to waste my time trying to figure out how to fix it.
In fact I don't need any extras they provide, a bare android would suffice to me if all the sensors and connectivity would be available. But I'm not familiar with internals of building vendor specific stuff. My understanding was that I need proprietary parts together with AOSP to build a working ROM and that's one of the things CM guys did. Correct me if I'm wrong.

Nope AOSP is as easy to build now
Go to the android site and follow directions
Google for "build android"
At the part when doing repo init you need to get the right branch
Go to "build for devices" then scroll down for recommended branches and look for the dream
One thing you'll need to do differently is do "make otapackage" instead of plain "make"
And once that's done you'll need to tweak the zip and get rid of the "recovery" folder and tweak the updater-script
Oh yeah, and I don't know exactly how you would do this part, but you'll need to get the source for a newer kernel in there, like ezterry kernel and use it with 2708+ radio/spl
Unless you wanna use the AOSP kernel & spl & radio which is old
What I did is just flash his kernel after the rom, but you want to do kernel stuff so yeah...

Good Afternoon, people.
I am brazilian and I have a smartphone that did not get into US and European market. It's name is "Motorola D3" and the number associate to it is "XT920".
Motorola Brazil were suposed to provide de newest rom for this device (marketing promissess). It took they almost 1 year to launch the Android Kitkat version 4.4.2.
The problem is: We want the Cyanogenmod in our device and all the newest ROM's.
That been said, I start to study to try yo port or Build a AOSP ROM to XT920 and, therefore, a CM11.
No threads on "how to port / build" a rom for a New device went trhough this problem. This device runs as a Mediatek MTK6577. I've seen that the kernel for this processor was released, but I don't know how to handle the kernel with the device and ROM properly.
Another doubt is: what is the difference between port and build a ROM? I've seen videos of porting and building and it is not clear to me.
I have reached the point where I have to download the drivers, but, in the tutorial the person was dealing with a NEXUS, wich is much easier to build, since it have a native android support.
Anyway, I want to keep this project going, and I really need some help with this questions.
Thankyou

You're screwed. MTK devices are extremely nightmarish to work with. Their kernel source is a mess and the platform source is an even bigger mess.
Even people who have had access to a complete OEM source code tree for an MT6589 device didn't succeed in getting the hacks to play nice with an AOSP source tree.
Android One has helped somewhat with devices that are released as part of the One program, but non-One MTK devices are still a nightmare.
The process of doing an AOSP bringup for a new device isn't particularly well defined because it is different for every device in existence. The only way to learn is by doing.
It helps a lot if a device with a similar chipset to yours is supported by whatever project you're trying to work with - for example most mid-to-high-end Qualcomm chipsets are not very difficult to work with. But MTK devices were nearly impossible to support with AOSP-derivative projects prior to One, and even after One, it seems like only Android One devices are "clean" enough to leverage Google's improvements to MTK support.
:/ should I waste more time or just drop it?

What should I do? I just quit without trying? I understand that this is a huge problem. But, if I decide to take the chalenge, is there a chance to succeed?
I am trying to figure this out and I didn't found an answer to this question: can I use the kernel that is packed with my stock ROM (provided by motorola) to build or port a CM11 ROM?
Sorry to bother, but I is really keeping me up at night

I have just a quick question, and I don't know why effort hasn't been made for anything like this, because this seems extremely important. Although, I'm not exactly sure if the infrastructure and design of Android allows it.
So how would it be possible to create a self-updating Android-based OS? Is it possible? I'm familiar with GNU/Linux, and how I can just upgrade the whole system, even kernel-level stuff, with just software updates (or apt-get dist-upgrade on Debian and Ubuntu, or pacman -Syu on Arch, etc...)
There's a really huge functionality gap missing in Android that developers really need to solve to have a solid foundation for their ROMs. The ROMs that have updates coming out for it, need to be able to self-update the system, instead of requiring it to be re-flashed. And usually I tend to do dirty flashes, because I don't want to have to back up all my data, just to restore it again. It's a waste of time, and technically inefficient.
If there are such things as self-updating android ROMs (specifically for the Galaxy Note 4) do they exist anywhere?
Bump.
Hello, still looking around for any solutions. Any ROMS with OTA updates or auto-updates at all that can be ported?
I wish I could figure out how to develop a solution myself, but I'm really not that skilled enough yet.
Another bump.
Thinking about updating my phone soon, as it's still running CM.

stock roms will have OTA, CM is done move to Lineage OS, Resurrection Remix OS which also have automatic OTA updates others you have to manually dirty or fresh install
I suppose the thread can be closed since RR will obviously have it in the future, even though nothing but stock ROMS really seem to have it now.
As for Lineage OS, I'm not too sure about unless they use Oreo's technology.
Hello everyone!! my team and i have been working on a different type of rom for the Z family to maximize the total experience.
the world best modular phone deserves the best OS we can offer so we figured why rewrite the wheel we used a slightly modded kernel version of Los 15.1 and ubuntu 16.04 into a new operating system. the old/dying project Maru is coming back in this way, and better than ever.
if you guys are interested we would like to share the rom once it is ready for RC1, well let me know what you think and we just might make this new rom public very soon.

just a little bit of what this looks like
Unleashing
This seems like one of the only ways to unleash the power of the mods since google and Motorola wont allow the community to get the code for the mods. If you need someone to do nightly compiles, I will happily help.
Wow, this is great! I’ve been locked down with Verizon, running a stock Moto Z. Love the mods but miss playing with Roms. I bought a Z2 Force but still on VZ. I bought a Sprint Z2 Force last month and unlocked the boot loader and rooted the phone. I haven’t flashed any Roms yet, I just waiting for the right one to come along. I’m not a developer but have flashed Roms since the First Moto Droid. I’ll be happy to give feedback. My Sprint is not my main phone, its just for play. I do want to unlock the sim in a month and bring the phone over to my Verizon account.
Not a Dev but been rooting and modding since htc Evo and original Xbox. Would love to help in any way possible.
ok so i only have a Z2 as of now in the Z family what i would like to know is what apps do you wish came built into a custom rom the you have found useful while on a custom rom? the goal is to become stable asap and we are seemingly stable now but we really want to polish this up.
we have a few more phone we are getting ready to start build for too but this phone is the main focus right now we have one of the devs on the team running this on the international s9. if todays build is ready for prime time we will post it asap but we are trying to get the install instructions done since it is a little work after the install.

It's not the same it works like maru but runs Los 15.1 not stock Android like maru and is on Ubuntu 16.04 not Debian. This room work the same but is a little different.
We made more progress last night. Hoping that we will have all the bugs worked out after today's report sync.
the command center widget that displays both the Moto mod battery and the phones battery
Hopefully u can make it so u don't have to log in to your G account to do the initial startup. And I 2nd apps needed r a good file explorer and maybe an alternative market like ACC or mobolism.
Any update on the development? Would really like to give this ROM a shot!
Anything new?
so quick update:
this is an unofficial build of maru os and if anyone is willing to help with development i would greatly appreciate the help. i am stuck at this moment since the guys i was working with are very busy at this moment. if you are serious about helping this progress to a stable build i can get you access to my build server to get this up and running once more. my phone is the one and only as of now and i have been enjoying it very much testing all the possibilities with external hardware. Devs please dm me tester will be selected once the builds are ready for single zip installs.
