[Q] Making those NAND System.img files

Howdy all,
Just wondering, how are the system.img files made? I have read that if it's a YAFFS image file, that the maximum filesize cannot exceed 128MB. However, I've seen on some NAND HD2 Android builds, the system.img filesize is >128MB.
My question is, what method are you guys using for making the NAND system.img files to flash within MAGLDR? (ie. is it like a ZIP archive with a .img extension on it)
I'm currently working on a remix of a ROM that I use (a hint is in my Sig), and I know that the update.zip method that was used on "true-Android" devices to change ROMs doesn't apply to our MAGLDR method now.
Cheers and I'm sure you'll see another ROM for the HD2 in the coming weeks!

The system.img is a yaffs2image. Google 'compiled windows unyaffs' use that program to take a peak inside the .img. When you're completely ready to make your own .img your gonna need a linux distro or cygwin w/mkyaff2image compiled. However I recomend compiling the mkfs.yaffs2 command if you are using linux. Alternatively you can place the /system/ directory you are trying to make an image on your SD and run that command in the terminal emulator in Android. It should look like this #mkyaffs2image /sdcard/system/ System.img
Hope that helps.

Does this give you write abilities so that files can be changed out pre-flash?

I think you have to dump them to a folder, then you can change what you want. Then do the yaffs2 cmd and it will package it back up to .img for flashing...

I think that a tutorial is in order. Someone who knows how to extract and replace files in a system.img needs to write a short tutorial on how to do it. - A simple step by step on how to decompile a system.img and re-compile it.
I for one would be extremely grateful because I finally worked out a perfect MMS patch and I'd like to be able to easily modify the builds pre-flash.

I have been trying to do that all night. I can unpack them but haven't got around to repacking them. For now all I do is install the build and push the patched file that I have and do a AD hardrest in MAGLDR. MMS 300-1024k and all TMO US app works.

That's not actually a Gingerbread build - it's just themed to look like one, but still got the same name

Another option is to connect to ADB or Android Commander before going through the initial setup(when it asks you to choose your language) and change the files then - use the PC to reboot the phone, not the phone's built-in reboot. This should take you right back to the setup screen where this time, should show United States localization.
Still a bit too much work. I'd like to be able to patch the build, flash it, and be good to go.

Windows
-----------------------------------------------------------------------------
Ok, let's start again. If you are using windows, google the said phrase above and you will find the precompiled utility 'unyaffs'.
Place the System.img you want to extract in a new directory with unyaffs.exe & drag the .img onto unyaffs. A command window will open and start extracting the files in the image to that same folder. You can now explore & edit/pull whatever you need to get things going. Once you have it the way you want copt it to your SD/root/ & make a folder for it with an obvious name like "Project" or "Test". Now to get it back into a bootable .img open Terminal Emulator in Android & enter the following
#mkyaffs2image /sdcard/NAMEofFOLDERuCHOSE/ System.img
**alternatively you can do this in windows itself if u have the utility compiled under cygwin or simular.
Linux
-----------------------------------------------------------------------------
Ok, you will need the unyaffs & mkfs.yaffs2 utilities compiled and working 1st off.
mkyaffs2image works to make the image however it fails upon flash with DFT Android Flasher. So I recomend mkfs.yaffs2 & have included it, you will need to place it in /usr/sbin/. If you have trouble copying it open a terminal and run "gksudo nautilus" then copy to the above mentioned directory.
**Now that those utilities are working let's get to work.
open a terminal and run 'unyaffs /home/yourusername/Desktop/targetdirectory/targetimage.img
copy/edit/pull the files you want. When your ready to build the image you are happy with open a terminal and run 'mkfs.yaffs2 /home/yourusername/Desktop/targetdirectory/ System.img'
Now your ready to flash !
System.img & Boot.img Contents
============================================================
System.img contains the entire root/system/ directory in Android
System/
app
bin
etc
fonts
framework
lib
lost+found
media
usr
xbin
build.prop
dmesg.txt
Boot.img contains
Boot/
initrd.gz
zImage
lost+found
============================================================
Hope that helps guys, It's my first tut on XDA
**EDIT: I included an archive for windows users that has unyaffs2.exe & cygwin1.dll
The Linux archive contains mkfs.yaffs2.x86, once moved to /usr/sbin/ rename to mkfs.yaffs2
The process works exactly the same for Boot.img

you need linux and run command by terminal
put them in /bin
http://www23.zippyshare.com/v/13814384/file.html
then you can yaffs or unyaffs
example
unyaffs /home/rafpigna/folder_with_img_you_wann_unpack/system.img
or
mkyaffs2image /home/rafpigna/folder_with_stuff_you_wanna_pack/ system.img

strange thing...when I open with unyaffs and then close with mkfs.yaffs2 or mkyaffs2image I get init: untracked pid 250 exited (where 250 varies) in a loop :S
some light for me?

btw no I didn't, because I want to make a rom (I'm not new to android development but that makes me think that I'm probably stupid )
Everything I do doesn't work.
Already tried something like:
- opened a premade working rom, exchanged just app and framework: no way
- exchanged everything but not bin/xbin/lib: no way
- exchanged just what was different between a stock and a premade leo rom: still no way
mmmh...

yaffs2
There is actually a way to modify files in a yaffs2 image but I've not done it my self yet. I'm 100% sure it's possible cuz everything is possible.... under Linux of course.
You need:
Linux, compiling skills, mounting skills, etc.
Basically for any other filesystems you can mount them as loop devices but not yaffs2. For yaffs2 you actually need a virtual mtd block device. once you have the mtd device you can mount the yaffs image on it.
For details google for: mounting yaffs image
and focus on virtual mtd block device.

This has a list of files to be pulled. Hope this helps. BTW michy I need help with a kernel, know anyone?

I'm Having a problem using on Linix, when i use the unyaffs trough the terminal it extracts the rom but not the squashed contents, which in the main apps and frame work are at on thoughs roms. I do get a file that says squashed but empty. I tried on cyanogens 6.1 rom and everything extracted fine.but that rom does not have a squashed folder, am i doing something wrong?

1. If i unyaffs System.img and manually remove some programs/aplications then create System.img with yaffs, does it programs will appear in apps and does my rom will be caused a more memory for other programs for installation?
2. Is it possible to unyaffs Boot.img then replace zimage with newest kernel like MDJ or hastarin then yaffs to new Boot.img, After that i suppose then this Android OS will be on new kernel???
3. And... If i remove zimage and initrd.gz from Boot.img, create new Boot.img without these two files and these two files copy to SD card and define that two files in flash.cfg for find on SD. Does it works?
Sorry for bad English.

How to unpack, edit and repack boot.img

*** I TAKE NO CREDIT. I JUST MADE A GUIDE TO HELP YOU***
A STEP BY STEP TUTORIAL :
I find many people struggling with unpacking a boot image and expecially repacking it. So here is a simple guide to unpack and repack the boot image.
>You need some tools so make sure you download all these.
List : (links available at bottom of page
split_bootimg.pl
repack_bootimg.pl
dsixda kitchen (you need some files from here)
Not to mention, a linux based system
> First you need to make some correction to repack_bootimg file(if downloaded from other source) . open it using gedit or some editor.
> check third line from bottom which is starting with system...If it is ending with $ARGV[2] then make this change
Add --base 0x19200000 and then close with " .
This now should look like
$ARGV[2] --base 0x19200000");
> Save it and exit. Now place boot.img and the two files in a folder(create new one. Don't mess it up)
> Now go to dsixda kitchen folder >tools >mkboot and copy all the files to your working directory
> Now you have mkbootfs.c and mkbootimg.c files along with needed header files. You have to make them executable. For that, run this command
gcc -o mkbootfs mkbootfs.c
change the permissions
chmod a+x ....(path)/mkbootfs
Now do the same for mkbootimg.c
gcc -o mkbootimg mkbootimg.c
change the permissions
chmod a+x ....(path)/mkbootimg
Now you are ready to go. Just navigate to directory in command prompt and type
./split_bootimg.pl boot.img
(or)
perl split_bootimg.pl boot.img
you will get some files. one is kernel and other is ramdisk. extract ramdisk.gz. Now again extract ramdisk(cpio file) . Make necessary changes.
To repack, use this command
perl repack-bootimg.pl <kernel_name> ramdisk_directory_name boot.img
( you need mkbootimg for this to work)
Bingo you have a boot.img which is ready to test.

If you are talking about using the kitchen for motorola, it supports only few devices.
Motorola Atrix (unconfirmed)
Motorola CLIQ / CLIQ XT
Motorola Droid (unconfirmed)
Motorola Milestone (unconfirmed) - you may need to remove the boot.img before building
here is moto list...If you are talking about repacking n stuff, it supports any vendor.

[UPDATE 22/08/12] ROM Cooking Guide (One Package)

This is how I made ROM, I'll try to write the steps as simple as I can. For advanced users only!
Update 22/08/11:
Revised packaging steps.
Update 13/08/11:
Removed unwanted method for ROM cooking.
Update 04/08/11:
Modified extract and repack ROM guide and added extracting system.rfs guide.
Things you need:
Base firmware
Archiver software (7zip recommended)
Any Linux environment to build ROM or Cygwin
APK Manager to optimize and decompile *.apk files
MagicISO (Optional) if you want to extract system.rfs
And the last thing is... You need enough experience in android world
So, here is the steps to cook a ROM:
Flash your phone with your desired base firmware
Make required modifications
Pull system.rfs from your phone by running this command on adb shell or Terminal Emulator:
Code:
dd if=/dev/stl12 of=/sdcard/system.rfs
Extract any *.tar.md5 files from your base firmware to your working folder with 7zip
Replace the current system.rfs with your modified one
EDIT: Pack your ROM by running this code via terminal or just pack it with 7zip/WinRAR as *.tar
Code:
tar -H ustar -c * >> ROMNAME.tar
change ROMNAME to your desired, well, ROM name.
Here is (yet) useful guide to modify your ROM.
Extract system files on system.rfs to make modding easier:
Extract PDA file (*.tar.md5) files with 7zip
Open system.rfs with MagicISO
To extract it, just drag and drop
NOTE: Never edit your ROM with MagicISO because the file permissions will be ignored, use MagicISO only for extracting files from system.rfs
Deodex, and Zipalign (optimize) your ROM apk files:
Ready to use deodex + root for KPN: http://forum.xda-developers.com/showthread.php?t=1196230
Ready to use deodex + root for KPH and other firmware: http://forum.xda-developers.com/showthread.php?t=1118048
Open APK Manager
To zipalign your apk files, in apk manager folder /place-apk-here-to-batch-optimize put your:
framework-res.apk, twframework-res.apk and all system apk
but not these:
AxT9IME, Calculator, Camera, Email, MMS, Phone, Screen Capture, Settings, Swype, Thinkdroid, Voice search
Choose Choose option 15
Then choose both (zp)
Let it run and done.
Now put back the apk files where they belong in the ROM.
How to put these apk files to my ROM? Copy these files to appropriate locations, such as /system/app to your ROM's /system/app, and etc.

As Linux, MagicISO read RFS image as a FAT filesystem. File permissions can not be maintained. A better way but need linux:
1. Mount system.rfs as FAT and mount it to /tmp/rfs
2. Make ext4 image, and mount it to /tmp/system
3. Copy /tmp/rfs contents to /tmp/system
4. Make modification inside /tmp/system
5. Fix file permissions inside /tmp/system
6. Umount both image
7. Make ODIN flashable image, contains system.rfs (now in ext4 format) and CF-Root-S5830 boot and recovery image (for ext4 support)
8. Boot to Windows and flash your new firmware using ODIN.

[Q] Mounting ext4 as data before boot + PA 2.00

Hi everyone.
I'm trying to increase data partition storage by using ph03n!x walkthru on Paranoid Android 1.992 and 2.0. I'm stuck at extracting boot.img in Working folder. The rom.zip itself don't have boot.img or boot folder so after extracting PA rom in dsixda kitchen i copied boot.img from Nandroid backup on SD. But while im trying to extract that boot.img there's an error
Code:
Working folder found
Android 'magic' header not found at start of boot.img
Cheching if it exists elsewhere ...
Warning: Android header not found in boot.img (unsupported format)
Error: kernel offset (page size) is 0
Press Enter to continue
So i took recovery.img from nandroid backup, renamed it to boot.img and extracting went fine, but there was some problems: could not find init.htcleo.rc file and "on fs" lines in init.rc file
Any suggestions how to do it? I think that real init.rc is placet in boot.img (not recovery.img), but how to extract it?

Do you have a working folder setup? If you do, then forget about the boot.img, just place the 'boot' directory from the ROM's zip (under /kernel/). If you do not have a Working folder setup, then follow my instructions to create a temporary ROM zip with the required folders - meta-inf, system and boot.

[Tutorial] Add TWRP to AOSP LP 5.0 boot.img

I've updated the boot.img for paxb build 504 with TWRP to replace CWM. Some were asking how to do this.
Always keep a backup of a file known as working. If your device doesn't boot after flashing a modified file, just reflash that backup.
To perform this mod on your own follow these steps:
1. Download and unpack the Android Image Kitchen
2. Extract the boot.img from the downloaded ROM to the kitchen directory
3. Unpack the image:
Code:
unpackimg.bat boot_cwm_pabx_504.img
Output:

Done!
This process will overwrite previously extracted contents!!!
4. Create a directory for the original image content, e.g. "boot_cwm_pabx_504" and COPY the created directories "ramdisk" and "split_img" into it. This ensures you can recreate it if necessary or access its original contents
5. Repeat step 4 for a downloaded TWRP (or any other recovery) image, e.g. "openrecovery-twrp-2.8.0.1-yuga.img".
6. Locate the "*-ramdisk.cpio.gz" file in the dirs from step 5, most likely in "split_img".
7. Ensure the "ramdisk" and "split_img" directories in the kitchen root dir are those from the image you want to modify (i.e. copy back from the folder created in step 4. Then remove the "*.cpio" from the "ramdisk\recovery" directory
8. Extract the TWRP "*.cpio" file from the "*-ramdisk.cpio.gz" in step 6 to "ramdisk\recovery" and rename it to "ramdisk-recovery.cpio"
9. rebuilt the image with the updated content:
Code:
repackimg.bat

10. Step 9 creates a file called "image-new.img". Rename it to something more self-explanatory, i.e. "boot_twrp_2.8.0.1_pabx_504.img"
11. To flash the file flash it like any other file using the new name:
Code:
adb reboot bootloader
fastboot flash boot boot_twrp_2.8.0.1_pabx_504.img
fastboot reboot
That's it, enjoy your new recovery.
Note: I had issues getting TWRP 2.8.1.0 working, so I'm still using the predecessor 2.8.0.1.
The latest pabx "boot.img" modified with TWRP is attached.

after restoring a Nandroid backup access to the internal storage isn't allowed anymore
Open a terminal or run through a adb shell:
Code:

Thank works dobře.TWRP I like long ....

cant understand what you mean in step 7 and 8..... i just unpacked boot.img (the img that i want to put a recovery on it) and then i created a folder and i copied split_img and ramdisk into it.....then i unpacked twrp.img and it replaced the previous split_img and ramdisk folders with the twrp ones..... i still have the folder i created with the original split_img and ramdisk folders from boot.img but i can understand what to do next....
well, sorry for that,...i think i got it now that i read it about 20 times..... one question though :
i copy ramdisk.cpio.gz from the twrp and i move it to the recovery folder of the boot img without extracting? just renaming it from ramdisk.cpio.gz to ramdisk-recovery.cpio ???

cant understand what you mean in step 7 and 8..... i just unpacked boot.img (the img that i want to put a recovery on it) and then i created a folder and i copied split_img and ramdisk into it.....then i unpacked twrp.img and it replaced the previous split_img and ramdisk folders with the twrp ones..... i still have the folder i created with the original split_img and ramdisk folders from boot.img but i can understand what to do next....
well, sorry for that,...i think i got it now that i read it about 20 times..... one question though :

Yeah I didn't fully understand that either, but i just tried it.
You delete ramdisk-recovery.cpio from /ramdisk.
You extract ramdisk.cpio.gz to the /ramdisk folder.
You rename it to ramdisk-recovery.cpio.
Repack image.
(note that when the kernel you use is already a dualrecovery kernel -lightning for example, cwm philz+twrp- and u want it to be multirom twrp, u need to edit init.sh also found in /ramdisk folder somewhere)
BTW thanks for this guide! I was messing with this a few days ago and I couldn't get it to work, thanks to you I now understand why!:thumbup:

Reread what I wrote.
You probably didn't extract ramdisk.cpio.gz, or you putted it into /split_img I think. Cuz I had that too, but if you follow the exact steps it will work!

no I did exactly what you said... I fully understood the instructions,I extracted it , I named it right and I moved it right... well, I will try again tomorrow but I don't think it will boot into it... Thomas boot.img has a cwm recovery ,does this have smthg to do with it?

What version of TWRP did you use? 2.8.1.0 will likely not work, use an older one instead.

Adjusted the description of step 8, should be more clear now what to do.
I've also added a note to point out explicitly that each run of "unpackimg.bat" will overwrite existing data.

Thank you so much for the guide! Really appreciate it =D

I used the latest twrp...maybe that's why....I will try again and I will post here

thank you sooooo much.... i did it with the second try...the only thing i changed was that i downoaded a previous version of twrp because it wont work with the latest one...thanks a lot.... what about cwm? is it the same proccess?

CWM is included already. But you could split the latest cm boot.img and grab ramdisk-recovery.cpio from ramdisk/sbin to get the most up to date version

is this mean can add TWRP into .FTF files ?
that will be awesome

Can anyone share their twrp included boot.img for the latest thomas release?

i tried to do this on the cm12 expirimental build and the boot.img of that zip doesnt have a recovery folder inside ramdisk folder... i did create one just to see if it works and it didnt

Look for a *.cpio or *.cpio.gz file and replace that accordingly. The place doesn't really matter for you, the ROM knows where to find it. CM might expect it respectively at another place. Will take a look later if I can find something...

Won't work like that. Needs a script to be inserted into the ramdisk, @pabx style, plus the recovery folder with ramdisk-recovery.cpio inside.

was thinking why the latest TWRP was not working, then realized that the TWRP is written to be loaded into the FotaKernal.
then it worked with TWRP flashed into FotaKernal.
have pabx_aosp_yuga-509 installed
1. Followed your steps exactly to create a new boot_pabx_aosp_yuga-509.img (with the latest TWRP image "recovery-twrp-2.8.4.1-yuga.img").
2. Flashed recovery-twrp-2.8.4.1-yuga.img into the FotaKernal.
3. Flashed the new boot_pabx_aosp_yuga-509.img
it works
Edit: On my Xperia Z c6002 (yuga)
