Hi all,
we are trying to build our own kernel for a Samsung Galaxy S (I9000XWJVB).
What we did so far:
- Download the correct sources from "opensource.samsung.com"
- Studied the README
- Installed cross-compiler toolchain
- Created ".config" as described in README
- Kernel compiled
Compilation worked fine -> zImage was available (but with only 2mb very)
OK, looks like initramfs is missing.
The first question is now, where to get / how to create a correct initramfs?
We copied the initramfs from Leshak and we extracted an ".cpio" from a working zImage.
Then we tried to use them in the ".config" (CONFIG_INITRAMFS_SOURCE) for kernel compilation.
Resultant zImage was larger (around 6mb) so it looks like something changed.
But once we installed the tared zImage on the phone (using Odin), the phone freezes during reboot.
Any advice how to progress here?
Is it possible to use Leshaks initramfs for all Galaxy S phones? Or is this only for a specific version? The CONFIG_INITRAMFS_SOURCE should point to the "initrd.arm.initramfs_list", correct? And not to the initramfs-folder?
And: Is there a way to get any type of kernel boot debugging message from the booting phone back to the PC (or the phone screen)?
Many thanks in advance!
I don't know much about kernels. But i will try to help. Have you tried other itiramfs or reconfig them?
There are not many people that will know answer so ask some kernel developers like hardcore, supercurio...

Just saw 2nd question. I think that it should point to intiramfs folder. You can zip all kernel files and upload it so i can take a look at them

we tried four different initramfs now, but ended up always with a freezing phone.
I would like to ask the kernel experts directly, but I'm new to this forum and not allowed to post in the developers forums. I hope that one of the gurus will reply to this thread.

My understanding is that the .list file will describe the structure of the initramfs folder and if this file is present, it should by used in the .config. Otherwise the .config should point to the folder.
Please correct me if I'm wrong.
But anyway, we tried both versions, none worked.

Use speedmod kernel patches with the readme file he has given..
or else you can go through supercurio threads also ...
they explained the kernel compilation methods....
thanks
Did you get this to work finally? I too am trying to compile and flash a custom kernel ( For SGS4G) I point my INIIRAMFS_SOURCE to an extracted initram dir, but the resulting boot zImage does not proceed past the initial boot screen(s) Please let me know if you succeeded, and if yes, how.
Thanks!
What I got the problem was about initramfs.cpio.
At that moment , the most important point you know is you should make the file in Linux..
When my friend made me a file is initramfs.cpio , it worked well.
But what I made in window made always troubles for compile.
So if you made a initramfs.cpio with hexeditor in window, try it in Linux again..
Thx!
I have installed Cyanogenmod 7.1 and modified my bootanimation. I would like to also modify my bootloader screen, the first screen that appears just after the phone boots. Please help on t this topic! Thanx in advance!
Well that's not as easy as changing the bootanimation.... Cause i think you need to build your own kernel.
Thanx! Could you please make or modify a kernel for the cyanogenmod 7.1 that I'm using. I'm pretty new to this android development, all I know is how to root, change bootanimation, and other basic things. Thanx in advance!
Ya kernel...read it can be changed in the param.lfs without having to build a kernel. Not sure how true this is in the case of mini.
What do I have to read and edit? And where can I find this param.lfs? Thanx in advance dude!
I replies on your other thread in Galaxy Mini General. Try modifying TASS.rle in root folder. I don't know if you need to unpack-then-repack your boot.img though.
Edit :
Since this "TASS.rle" doesn't exist in CM7 update zip file, then it means you do have to unpack your boot.img, open the ramdisk folder then edit the extracted TASS.rle" using image editor or something. I never modified TASS.rle so I don't know exactly how to do it.
If you're using Windows, you can use dsixda kitchen+custom cygwin package+Java Dev Kit to do the unpack+repack. It's somewhere in xda.

Thanx a lot dude! But are you sure it'll work? I'll try it out, but is there any simpler method than this. Some way that I can modify it using my phone itself? By the way are you using cyanogenmod 7.2 RC 3 by squadzone? How is it? Please give the link too... thanx in advance!
Like I said, I never modified TASS.rle so I have no clue if it will work or not. I did unpacked and repacked boot.img several times using dsixda kitchen and they worked.
I don't know if easier method exist, so I only suggest what I know from browsing.
It looks like in order to do what you want, several steps are needed :
1. Unpacking your boot.img into zImage file (kernel) and ramdisk folder.
Anything inside ramdisk.folder will be flashed into your system partition each time you boot your device. Examples are init.rc, default.prop and TASS.rle. You can do whatever you want with these files, say modifiying their contents, but the changes only persist as long as you do not boot your phone, which will restore them back to initial state as I explained above.
2. Converting TASS.rle found inside ramdisk folder into editable format such as PNG
3. Modifying the converted PNG in point 2 (using Photoshop or other app)
4. Re-converting the modified PNG from point 3 back into RLE format
5. Re-packing (compiling) zImage file and ramdisk folder (having modified TASS.rle from point 4) back into boot.img
6. Flashing boot.img from point 5 into your phone.
To make it short, you need to learn how to :
1. Unpack and repack boot.img, which you can do using dsixda kitchen from here : http://forum.xda-developers.com/showthread.php?t=633246
2. Converting RLE to PNG and vice versa. More info here : http://forum.xda-developers.com/showthread.php?p=20128066
3. Flashing boot.img into phone. You can compress your boot.img into TAR (type this in cygwin shell window "tar -cf boot.img.tar boot.img" and flash it using ODIN with one package option or you can create a flashable zip file.
CM 7.2 RC3 works great for me, better than RC2; but that's my personal judgement and there's a chance you will not agree with me after you try it.
Head over to CM 7.2-RC3 by squazone for download link.

@distan
I used Ketut's tools to unpack before...it also had a little something to convert .Rle to raw...only came to my mind now.
Will give this a try tomo.
Shouldn't be that difficult...I think.
And @Nelson
Definitely can't be done in phone.
This is much more than that.

Nice info buddy, I recall reading his thread too and it's applicable on Galaxy Mini, since both Ace and Galaxy Mini have the same kernel base address and command line parameter (CMIIW).
But I'm not sure if it will work under custom cygwin by dsixda (in case you want to use it under Windows)

I've attached the tass.rle converted to tass.png thanks to ketut.
but this is only one of the 2 images that appear while booting.
I have to dump the stl6 to find the other i think...but dumping stl5 bricks the phone (stepph) so a little nervous...but i might give it a try.
edit: no harm done.
but stl6 had nothing....anyone got any ideas?
the .jpg or whatever is hidden somewhere, at least that is how it is for galaxy s variants.
dsixda's Android Kitchen - Now for Samsung Galaxy SIII GT-I9300
Compatible with Windows (Cygwin) / Linux / Mac OS X
The following is a guide to assist you with creating your own Samsung Galaxy SIII GT-I9300(T) custom ROMs with the kitchen. This is NOT a guide to help you become Cyanogen or do fancy things with AOSP, but it may be your springboard to bigger things in the future.
Some of you already know about the Android Kitchen. It is a project I started on back in February 2010 to help newbies create their own custom ROMs and learn more about Android. As of the latest versions, you can now create your own Galaxy S3 I9300 ROMs with the kitchen.
NOTE: This guide may also work for other Samsung devices. So if you were told to come here and you have a different device, it was not an error - just make sure you use a base ROM from your own device, not from the I9300! For all other Galaxy S3 variants, this guide might not be exactly the one you're looking for. There may be support for your S3 device in the kitchen, but I'd need to post different instructions. Check the first post of the kitchen thread for any updates for linked instructions.
I'd like to thank klander for testing and providing feedback, which is always appreciated!
[MAIN PAGE] [RELEASE NOTES] [FAQ - page 1] [FAQ - page 2]
PROCEDURE FOR MAKING YOUR ROM:
NOTE: If you have a non-I9300 device and were told to follow these instructions, then use a base ROM from that device, NOT a ROM meant for the I9300!! The same steps below, however, (and common sense) should be used.
First, you need a rooted Samsung Galaxy S3 I9300 with a custom recovery menu, which allows flashing of custom ROMs.
Visit the Android Kitchen thread to download the kitchen. Then, follow the link to the FAQ which will show you how to install it on Windows, Linux or Mac OS X. Ensure you read the FAQ carefully.
Put one or more of your base ROM(s) under the original_update folder. For the Samsung Galaxy S3 I9300, there is support for the following formats (that I know of) which can be placed in that folder:
Stock firmware:
system.img, boot.img, cache.img (and optionally: modem.bin)
TAR/ZIP file containing the above. NOTE: If the TAR file name ends with "MD5", remove the MD5 part from the name.
OR Custom ROM:
must be a ZIP file created by the kitchen from the stock firmware (NOTE: The kitchen may NOT support custom ROMs created through other methods such as CyanogenMod, due to potential file structure incompatibility issues)
OR Nandroid backup from custom recovery image:
system.img, cache.img and boot.img
system.ext4.tar, cache.ext4.tar and boot.img
Here are some basic steps to creating your first ROM after you have your base of files under original_update (more options are available in the kitchen):
Start the kitchen with: ./menu
Create a working folder (by choosing your base ROM)
Root your ROM
Add Busybox
Optional: Disable boot sounds
Optional: In the Advanced options menu: De-odex your ROM (your mileage may vary as to whether this works 100%)
Optional: Add or remove the modem.bin from your working folder
Build ROM
The ROM is built into a ZIP file meant for flashing from the custom recovery menu. No Odin. Make a Nandroid backup of your current system before you flash anything!
Some notes:
Just select the defaults whenever you are asked about something in the kitchen and are unsure whether to type 'y' or 'n'.
There are lots of questions answered in the FAQ in Posts 3 and 4 of the main Android Kitchen thread. So please go through that first if you have any issues.
For the benefit of other readers and to prevent confusion, please only discuss the Samsung Galaxy SIII GT-I9300 in this thread!
Most of all, have patience, take your time and enjoy!!
just what i need
I have a de-bloat script if you want a copy to convert to a kitchen script. It's perl calling system values and the kitchen.
Are we still meant to be extracting the img files manually to get them working?

I'm not doing additional work, but if you'd like you could make a plugin for the kitchen, which would go under the /scripts/plugins folder and can be accessed from the Advanced menu of the kitchen. I can advertise it in the kitchen thread (in the plugins section) as a separate download under your name.

With Cygwin the kitchen will give you instructions on which program to open and how to use it (manually). The programs are found in the kitchen.
With Linux/Mac, it is all automated and very quick.
Just when I thought this kitchen was a goner, you came along and made it work again
I have just put the French zip into the kitchen and it fails to extract the img files.
Available ROMs:
(1) I9300XXDLIH_I9300VFGDLJ1_SFR.zip
Enter selection number (default=1, cancel=0, r=refresh):
Selected I9300XXDLIH_I9300VFGDLJ1_SFR.zip
The new working folder will be named WORKING_101712_171605
Change the name (y/n)? (default: n):
Creating working folder WORKING_101712_171605 ...
Extracting ROM ...
Error: No system folder found!
Press Enter to continue

It works after manually extracting so no big deal

If the zip contains a tar file then it's not going to work, you need to unzip the tar file.
The best tool for deodex Roms!

just wanted to let u know that when cooking my rom with ur kitchen, awesome by the way, i was getting constant hang at logo on boot. i went back to the beginning as it worked and booted and just added bit by bit until i found the issue. the issue was adding busybox install run parts. it took me a day to figure this out. i went through kernel to framework and nothing fixed this issue where booting just to logo then stuck. finally deleted working folder, went back to a basic rom, slowly added root, then busybox, deodex etc. i dont know if this issue is specific to just me and my particular build but just putting it out there for others wanting to use this excellent kitchen on their i9305.

Did you create a /system/etc/init.d folder with your custom scripts after enabling the Busybox Run-parts? That option is quite old but I have not seen anyone try or test it with any of the Galaxies. Maybe when you have time next time, do a logcat while it boots and see what the problem is (assuming you had the init.d folder created already). Thanks

yea i created the init.d folder first, (using v29 so it gives u warning anyways), but it still does this. i have to add init.d support manually through my script. but this is awesome, i just gotta remember not to use that feature.. i did both logcat and recovery logs but couldnt make heads or tails of it. it was easier to go back through ur kitchen, add 1 feature at a time until i found the culprit. thanks heaps

Hi friends of XDA,
I think this might be helpfull for some of you trying to compile kernel from source for S5830i, for the first time.
If you are following the great tutorials to build your first kenrel like:
http://forum.xda-developers.com/showthread.php?t=1748297 from thewadegeek
The first thing taht will happen, is that you cant pull defconfig from /proc/config.gz for S5830i.
Why? There is no such file for your device in there.
Normally the next you will do, is go to the stock sources readme file. And will find out the defconfig is totoro_defconfig
You will compile the kernel with no errors, and you will feel very happy, until you flash your recently compiled kernel and see that you get stuck in the boot_logo screen.
Ok, dont panic, solution is very easy. Samsung readme file is a general readme.
Here is the quid of the question:
totoro_defconfig is not the correct defconfig for S5830i.
S5830i defconfig is bcm21553_cooperve_defconfig
You will find this defconfig in the sources, at:
common/arch/arm/configs folder
Hope this helped. If it helped dont doubt to press the thanks button, this will be very appreciated.
Thank you and sweet kernel development.
Samsung's readme file isn't general, they just took the Galaxy Y's readme (even the model says GT 5360).
What's stranger is that the CHN sources have the correct info.
Also, I didn't need to pull anything. I just used the default config:
Code:
export ARCH=arm
export CROSS_COMPILE=<path>
make bcm21553_cooperve_defconfig
make -j16
Hi GermainZ,
Thats right,never had a look at the CHN readme. I wonder why the other sources are uploaded looooollll strange Samsun guys.
Never the less, forgot to post the next in the original thread.
I recomend to have an original copy of bcm21553_cooperve_defconfig as when you start modifing it some options may fail and its recomended to have a fresh one to copy paste quicly.
Even more for my kernel i copy original file and rename it to nit_defconfig and give it a version number ej nit01_defconfig, its agood practice have latest working defconfig as you will be modifying the file a lot, btw nit is how i call my kernel as you all ready know, this comes from new innovative technologies the name of one of my companys i created recently
But good appreciation GermainZ is always my pleasure to talk with you

Cyanogenmod does not support my device officially but there is unofficial support for it.
my problem is don't understand how to do MANUAL step.
could anyone explain it for me?
note that i'm using ubuntu porting guide in ubuntu touch wiki ...
thanks in advance ...
anyone help me?
You may find a manifest file in the unofficial repository, a xml file, maybe.
According to guide, the project named kernal, device & vendor need to be added to the .repo/local_manifests/roomservice.xml, which does not exist, and you need to create yourself.
But I also saw some manifest files containing remove-project. Not sure if that should also be added to the roomservice.xml.
