Hello,
Sorry for this very basic question, I am just wondering what is the difference between a Kernel and a ROM? I see in the development forum there are lots of new Kernels, what are these actually optimizing except underclocking or undervolting (understand that terminology). I am also wondering if the Kernels are specific for the original Nexus One 2.1 Android or can you install for example Modaco or Cyan ROM and then a different random Kernel?
Thanks!
To my understanding, a kernel is what directly interacts with the hardware. Every OS has this, but it's more customizable on our phones since it's based on Linux. The Rom contains the OS itself, and the software and file structure therein. The kernel even can tell the OS how fast the processor goes and how much juice to use from the battery.
Hope that makes sense, as I'm no expert. You can mix and match the two as far as I know. I've mixed them, anyway.
Halorin,
Based on what you said, with my stock vibrant ROM 2.1 JI6 update, it is possible to change the kernel or install another kernel (like the CM kernel)?

That is really a question better suited to the rom 's development thread, but in general yes you can flash a different kernel. Some kernel/rom combinations work better than others, but you really wont know until you try. Get comfortable with nandroid backups and start trying out different kernel combinations until you find one you like.
Usually most custom roms will include a kernel but they usually have tweaks like coding for 720p, oc, and audio tweaks and what not. Alsways do a nandroid back up and start exploring. When flashing kernels always wipe, I think their are exceptions but its best to wipe just in case. Browse XDA, download a kernel from your phone browser, rom manager install from SD, should be in your downloads folder, backup and wipe, repeat until your phone does what you want.

which is the better to install???
Thank you your post..
but i can't understand clearly.
so.,
which one is better to install NewRom / Kernal. for android phones.
Neither one is better it just depends on what you want to do.
If you want to totally change over your phone to look and function differently then you need to flash a ROM if you just want to keep the same look but want to enable lets say overclocking then flash an overclocked kernel. If it has to do with the hardware mostly then it's probably something that the kernel can change. Although like mentioned above if you flash a ROM most of the time it will come with a custom kernel.

What he said.
ROMs and kernels are two separate things that have two separate functions. Neither is better than the other, but they do complement each other.

I know both Dude Random21 and codesplice have gone into this, but to try and give a bit more info...
The kernel is kinda like the nervous system of the body. It directly interacts with the hardware (which is how it is able to adjust CPU speed) and it is what allows the ROM to function.
The ROM is the rest of the body. Every other aspect of the phone. In fact, most ROMs include custom kernels. Various ROMs give you various features/enhancements/bugfixes. You will probably notice the biggest change in your phone if you load a custom ROM. Most people load the custom kernels to help with battery life as a lot of them allow you to lower the phones minimum processing speed from 245Mhz to 128MHz.
The ROM can change so many different aspects of how the phone works. There is CyanogenMod which is based off of stock Android with a lot of tweaks, bugfixes, and new features added. There is also MIUI, which is similar to the iOS style (not the same, but much closer than stock Android), and then there are a ton others out there.
Then which Rom is best for my samsung galaxy s???
so i am using froyo.jpjpg on my galaxys.
i want to flash new Rom with upgaraded to gingerbread.
can i flash only rom../ kernal also.
which is best Rom for samsung galaxys.
cynogenmod, miui, .?????
battery drain is very fast now ian running rom/kernal.
Start by going to the forum for your phone.

Nandbackup + Rom & Kernel
One question: when I do a backup with CWM, it is the Nandroid backup you talk about, correct...? Same thing? So, if I do a backup with CWM, it's a backup only of the ROM, or also the stock Kernel...? Imagine that I do a Rom (GingerDX for example), and flash with a custom Kernel.... If things go bad and I do a restore from my backup (stock) CWM, what do I restore? Rom, or Rom + (stock) Kernel...?
Yes, a backup that is done in ClockworkMod (or Amon_RA) is considered a nandroid backup. And this takes a complete snapshot of your system. Your ROM, your kernel, your apps and your data are all inlcuded. The only thing that isn't included is the fat partition on your sdcard. So if things go bad and you restore your nandroid backup, it will go back to however it was when you made the backup.
thanks a lot. reading this thread clear up a lot of things
Hi!
I am currently running Lite'ning ROM 6.1. XXKH3 Kernel version 2.6.35.11-ninphetamine-2.0.5+ [email protected] #20 on SGSII. Phew.
I've tried a lot of ROMS including MIUI, villain, galmetMIUI ICS version . I like Lite'ning ROM because it gave me the least (virtually Nil) problems (FCs/ reboots) and has almost all the features I need (TV-out that's missing from MIUI, good camera with panorama mode, Recording mode in phone). However I miss the CIFS feature. Is it because the kernel does not support it? Can I get CIFS support if I flash another kernel? Any suggesstions on which Kernel should I flash? I realise that this ROM is pretty old now so Can I get additional features with a newer Kernel.

So I've just recently flashed my vogue with myns donut for a couple days and It was pretty good. The camera worked but no video and neither did the gps. I understand that for verizon you have to follow a specific procudure to get that to work so that makes sense. I'm just curious to what android roms they are using for their vougue. I'm looking for one that has the most working features. Let me know what it is and how you had it set up.
For my Fresh Froyo although remember android no is 100% stable but Fresh Froyo is very good.
If you know what you want my barebones build is known to be one of the fastest and most stable builds. With that though you need to get the apk's to what you want and add them in. It is meant to be as cut down to the minimum to be light and lithe on our devices.
Another way to get apps is to use the market, I have the most recent version of the market in my build. CM 6.1 is Froyo based so you have video and all the other froyo features.

I tested more than 10 ROM including the yours and I am sorry to tell you than ever before me to worked well even the last released CM 6.1, does not work properly with the kernel that is in my signature and is the one that works best with the USB sync and just by this already this ruled out your ROM, so I'm still saying Fresh Froyo for me is the more stable and clean ROM of froyo that I tested.

This is my situation too....as I posted above. I know how to install, but am unsure of exactly what you are recommending as to the Fresh Froyo files. Thanks again.
Well try to be brief to that understand... (my English is very bad).
They must go to the thread of Fresh Froyo and go to this page, there download the ROM latest although I recommend the penultimate that is in my signature the most recent gave me problems.
The ROM download whith the name system-froyo-us-unodex-XX-XX-XX (X are date) have to rename it to androidinstall.tgz and copy in the ANDBOOT folder then locate the kernel of their choice here, the most recent is 2.6.32 although I recommend 2.6.25 which is in my signature if need USB mass storage in 2.6.32 doesn't work.
For the rest follow the installation guide in NAND is here and everything should go well.
Not be as it is done for HARET but here also the Guide to install in haret. I believe with what I said is more than enough so installed android in their device.
Best regards.

It works in Ubuntu Linux. It does not work for Windows 7, at least that I could configure successfully.
I'm using SuperFroyo and the 2.6.32.9 Kernel and a few things I noticed to make it more stable: don't use a Task Killer and be sparing in your use of a cache cleaner. Seriously, a week of doing that has really helped things. Trust the Linux Kernel, it's not Windows. I also used Autostarts to prevent a few of the more eager apps from starting automatically post-boot, but that's optional.

I cannot as I do not have Clemsyn's kernel so I cannot commit his fixes for stability to git. As far as the git kernel goes it already has those fixes.
Also with fresh froyo or any AOSP build you will not have as much speed since it does not have all the Cyanogen Mod tweaks.
So it loses a lot of those tweaks but I can say 1 thing about cm6.1 and 7 so far, they are getting rather large themselves, I can look into cm7 for hero and find atleast 10 apks that just take up space or are only good once

Does seem contradictory as to not use a task killer, the task killer close applications that are open and if you don't use are accumulating and this put slow the phone, the APP autostarts manager if I heard but none that worked well in my Vogue, which do you use?

You don't need a task killer. The newer versions of Android will shut down apps that aren't being used if the resources are needed elsewhere. If you run a Advanced Task Killer or something similar, it will use system resources shutting down apps that then re-open themselves, which the task killer will again kill. It drains the battery and makes the OS unstable. Uninstall your task killer for a few days and see if it helps.
I use Autostarts because it fixed a problem--the music player started randomly. I also use it to prevent some apps from starting up but it is probably not necessary.
Hi there! I'm new to the forum and to android as well.

Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
Is there a way to install some good kernel (like speedmod) and naked ROM (not someones mod, i.e. a stock android ROM without any additions from third party developers)? Is it hard to make my own ROM based on stock ROM (without touching the kernel, even tough I looked at the code and read books about the linux kernel, I dont yet consider my self a guru to be able to make my own kernel for android), just the modification and custom applications?
Thanks a lot guys!
Everyone has a kernel - even if you don't mod your phone at all. It wouldn't work without one!
Now, if you flash a ROM, you change the whole system including the kernel. If you flash a kernel, you're only changing the core piece of your system.

A rom is a full firmware .
A kernel is the bit at the base level between processors and OS .Or just as you said .
Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
YES but its at your risk though SGS is relatively un brick able .
Simplest upgrade would be via Rom Kitchen and build your own rom .
Choose base rom kernel modem and CSC to suit plus themes and apps .

The kernel in android is essentially just a customized Linux kernel. The ROM is basically the application layer and the framework. Usually ROMs include kernels, but you can flash a different compatible kernel.
Firmware usually refers to either all the basic software on your phone (minus the apps) or the ROM, csc and modem.
You can definetly flash a custom kernel onto a stock ROM, which will improve performance a great deal even without a custom ROM. Find instructions aplenty here on XDA.

By un brick able you mean that its hard to brick it, or if I brick it its hard to un brick (fix) it then?
Also I'm having a hard understanding, if kernel is the thing that manages the hardware and also responsible for lagfix then kernel is really what matters for the performance of the phone. How a ROM could improve phones performance?
Also one more questions:
As I understand CSC and modem are connectivity related files (3G internet, APNS etc) right? So its better not to touch them when flashing custom ROM/kernel?
Thanks a lot again!
JJEgan means it's really hard to get to brick your SGS.
The kernel is responsible for the proper functionality and cooperation between hardware parts. As for SGS, it is a common belief that Samsung's RFS is not as robust or "agile" as ext4 FS. Thus, converting RFS to ext4 should increase device's performance (the time needed for the read/write operations to take place is decreased). BUT, in order for the device to function properly, the kernel MUST support ext4 as a file system format otherwise it won't work anymore (This could happen after installing a stock kernel on a device that uses some filesystem apart from rfs). Samsung's stock kernel does not, so you have to replace it, if that's the case.
(E.g. If you format a USB drive under Windows 7 with "exFAT" as its filesystem, you won't be able to access it through Windows XP for example, because XP does not support "exFAT" - Different kernels & Different OS version ).
Yes, CSC and modem.bin are what makes your device a TELEPHONE, too Connectivity issues between your operator and your handset depend on those files. If you can find the latest COMPATIBLE modem file, then go for it.
Thanks for the explanation!
As for CSC and modem, by compatible you mean the same version (XXJPY for example)? How do I know they are compatible with my phone?
Thanks a lot again!
the CSC doesnt have to match the baseband. for exapmle, you can have XXJPY baseband and XXJQ1 modem. (thats what i used to run)
its all about finding the right modem for your region, you want to make sure you get good connections dont ya ? modems affect SMS, Calls, Data, WIFI, so on.....
so you want the right one. If you go to rom kitchen, you can see all the modems and what region they cover
Thanks!
But is there a way not to touch the CSC/modem when flashing custom kernel/ROM? I'm really afraid to mess with those.
Also could someone refer to this question:

Think of the kernel as the drivers and the ROM as the OS. If your drivers are from 1987, windows 7 wont run well, if at all. However, you can have the newest 2011 drivers installed on Windows 95....same thing. Kernel and ROM must be well suited and work together for a good experience.

Actually if you are flashing a three file firmware with odin, PDA is the ROM, which in this case usually includes a kernel.
If you are flashing a kernel alone onto an already installed ROM, then the kernel is put in the PDA field.

Gingerbread needs a different kernel than Froyo, right?
every firmwarerelease (JVQ, JVP, JVR, JVS, etc..) has its own kernel version.
but with talondev im not sure, cuz there is no distinction between the kernel versions.
with all other custom kernel releases you have specific kernel versions.

Hi guys!
Since two days I'm trying to create a ROM based on HTC Sense, porting from HTC Desire to our Nexus One using, as a base, the RCADSmixHD ROM.
I've been able to complete the entire package .zip and installing succesfully, BUT at reboot I'm stuck at the Nexus logo...
Do you think it's a kernel-related issue?
I really don't have any other ideas...
EDIT: I'd also like to know how to develop/modify a kernel for our Nexus One, but based on HTC roms... Someone has guides/links?
Try to Flash this Kernel: 2.6.35.6-eViL--10-7--1-wmcfg by eViL D:
You can find dl link here : http://forum.xda-developers.com/showpost.php?p=16995049&postcount=2
I had problems with the kernel include in RCADS on my N1
Thanks but no changes here... BTW the kernel included in RCADS rom works with my Nexus.. But here in this new ROM that I'm trying to develop I don't know what's wrong...
My guess there's something wrong with the ROM itself you probably have a few lines of code somewhere that are not working right. Were you able to compile the code on your computer?
Well, actually I'm trying to port a Sense ROM from HTC Desire with 250mb fit into /system/... I think that's the problem because my Nexus One could have bad blocks and/or less space into /system/, so this ROM wouldn't fit. I think so.
Regarding the code, I haven't written any kind of code, apart from looking at updater-script to be ok... Other suggestions? Thanks anyway, much appreciated
Now I'm trying to port a different ROM, the Desire S Gingerbread 2.3.5 with Sense 3.0!
But after replacing many folders and files from a Sense Rom of the Nexus One and the target Sense Rom that I'm developing, I have replaced boot.img and edited the updater-script properly (I think).
After installation, it's stuck at the Nexus logo... always!
What's wrong????????
Look at your logcat.
And at your /proc/kmsg.
If you don't know what these 2 mean - read up on those, use some googling.
If you can't - I believe you won't be able to develop anything worthy, or anything at all.
Moreover, Nexus has 145MB on /system partition. You need to utilize SD-EXT partition and symlink parts of the ROM to make it fit.
If I'm speaking Chinese and you can't figure it out - read the previous paragraph
From your posts I can't detrmine if you are developing or just trying to flash the rom to your phone, since you haven't done any coding. Am I misunderstanding?

You're right, because I'm not coding for a completely new ROM..
I'm just trying to "assemble" different pieces of ROMs together, a porting!
The only thing to "code" is the updater-script (or update-script)...
I have some errors there and I can't really determine why certain things goes wrong.. for now I don't have full knowledge of system partitions of Android.
And now I don't have enough time to fully explore this complex world
I have just tried for a couple of days...

What did you add to the updater-script? And which folders specifically did you replace and change? And did you use a rooted ROM or the OTA one for the desire?
@Ace42:
Hi, I had used a rooted ROM from the Desire thread and I have followed this pretty useful guide which illustrates how to port Sense Roms:
http://forum.xda-developers.com/showthread.php?t=1222746
I have also had a look at almost all the files into each folders to see if there was differences in the code between the 2 roms..!
BTW the problem is in the updater-script...
For example I'm not able to mount "sd-ext", which is one of the most important steps to do for the Rom to being able to run into the device.
Look at that link properly, porting sense to OTHER SENSE DEVICES.
N1 isn't a sense device.
First, porting is more than replacing your boot.img and changing your update-script.
Like the other user said, you need to symlink files to your SD card cause N1 just isn't big enough.
Second, you're taking roms from other devices, most probably you'd have to re-write or mod the drivers.
Third, Porting just isn't that easy.
@illuminarias:
-> I know that, and in fact N1 becomes a Sense device when it has a Sense rom already installed... so it can be compared with other Sense devices.
-> I also know that we must symlink files, and you do that by adding lines of code into the updater-script (or update-script)!
-> If no one starts from something, how do you think that development for N1 can continue??

The n1 also runs miui, is comparable to the m1? No.

I'm sorry but personally I love HTC Sense, not a-bad-copy-of-iPhone such as MIUI.
And since now I don't have money to change the device, I'll stick with this for other time.
Cheers

Yes, the same for me. I Love my nexus one with sense. Currently i also working on a gb sense rom for my nexus. Update Script is done and system should fit now with 151mb into the nexus rom. I ll will try to install & boot it at the weekend. Base was the currrent 2.3.3 Desire Release... Hopefully it fits into the small system and boots , to get logcats to work with...
If someone want to help & try, please contact me. I can upload the rom then to test. Currently i don´t have a lot of time , maybe together we get a working release...
@Deep-Knight:
Yep, I was working yesterday evening with the official Desire gingerbread update from HTC, but, as always, I'm stuck at the Nexus logo, after the installation is done... :/
I think I'm doing something wrong with system partition.. I know that our N1 can handle only 150mb for /system...
But I must admit that I'm using almost the same updater-script and boot.img as the N1Sensation v0.5 rom or RCADSmixHD rom..

Just make a thread and upload your beta version, theres a plenty of people here able to test and help.
Thank you Menelkir for your interest!
But first I'll have to create something useful.. Maybe later on I'll create a new thread..
Till now I'm using some HTC Desire's ROM from the dedicated section here at XDA.
Stay tuned guys
As always graphical glithces will not be solved, until HTC releases Desire's Source Code..
The code is released already.
Unfortunately, the real trouble with porting ROMs is fixing the things that don't work - which will include trackball, hotspot etc - and this is the part where most of ROMs fail, because very few developers are skilled enough for that.
i have come from a htc hd2 so i like to change roms alot.
what should i do with the galaxy note ?
i would like ICS so what are the steps ?
any help please
Have a good search round this forum and make sure you understand clearly how everything works before you decide to start flashing, I came from the HTC Desire and the Galaxy Note is a whole different ball game. Enjoy you new Galaxy Note
is the official ics update any good ?
what does rooting do ?
I personally didn't like the official ICS update, that is when I decided to flash a custom ROM.
Rooting gives you more control over your phone, lets you install apps like "Titanium Backup" that require root permissions to run.
i have the la6 kernel
im lost

Apparently this really depends on your location. For example the one Samsung released here (France, 4 months after being announced, too) was so broken it bricked a number of terminals and was subsequently withdrawn. With no word of when a fix will come.
Apparently other areas had working systems. One would think it would just be a matter of strings to translate and a few apps to package, so it's all very puzzling to someone who isn't familiar with Android (I've been intimately familiar with Linux for more than 20 years, and Unix before that, but I still don't get it).
And then, as you'll see by browsing the forums, many people seem to have issues with ICS. Issues that (IMO) just don't seem to make much sense in a system that would have been tested for a couple days by an intern somewhere...
OTOH, many people apparently have no issues.
So as with everything on the network, I suppose YMMV, take it with a grain of salt, yada yada... void where applicable.
See if anything is reported about your proposed (if any) update. Then decide if it's worth it (maybe it is).

Same as on any other terminal ? Lets you access functions that are typically "off limits". Among the most useful ones, you can now read/write anywhere. Which means you can allow/deny anything for any application. And notably block all those silly annoying bundled apps so they won't want to update any more, or, if you like, even start (a process known as freezing).
Have a look at the videos in my signature once..
For Rom official one is good but custom ones are great..
All roms are unique in their own way...the ones that stand out as totally awesome are Paranoid Android and TMT Hybrid IMUI...
Its your choice...
thanks guys
does the la6 kernel complicate things ?

Yes.... Speedmod is adviced for stock ics...

yes, just be careful, follow instruction to the dot, and don't take any shortcuts,
also, it's good to have tb backup, as additional security precaution

1. probably, but make sure in paranoid thread,
2. I assume you have done cwm backup, which will be rather useless when switching ROMs, having tb (i.e.Titanium Backup) backup you can generally restore your apps and data between roms (except for the system ones)

yes all backed up with cwm and tb.

And that was the right thing to have for the time being, too bad you hurried on to ICS. In my opinion, when you have a new phone, you have to know it, enjoy it, love it ( ? ), installed a couple of hundred apps, and then, after being more than familiar whith it, it would be time to upgrade it, tweak it, etc., so the change could be apreciatte. It's like eating always the desert at first, withouth eating the soup and the salad.
As for rooting, if you had to ask, you probably did't need to root, but since that's already done, I'll give you a hint. There is one VERY interesting thing about rooting which anyone would find usefull. The posibility of using a Firewall. In this way, you could not only block those annoying ads (and save a little battery since the ads have to download from Internet). You can also protect your device from troyan / spy applications, which are increasingly expanding in android. For example, a simple sound board app, or a screen saver, ¿why should it use your internet connection? ¿To what ends?
Enjoy the Note, it's a hell of a phone.
