Hi,
I would like to edit an official system rom.
I can have it in 2 format a NBH file, but i did not found a way to extract it or the file directly extracted from the phone with the command line:
cat /dev/mtd/mtd3 > /sdcard/mtd3.img.
It seems there is a way to extract it with a command line like:
gunzip -c mtd3.img | cpio -i
but i always have errors when laucnh it, like not in gzip format etc...
Does anybody has any clue about this?
Bye

unyaffs it?
Just tried and it gave:
Segmentation Fault

Herc.
Try using nandroid to back it up, copy system.img to your nix box (cygwin might work), and unyaffs it. The contents will be extracted to the current directory, so set yourself up a working directory. Just a guess, but I think your image is becoming corrupted.
It Worked.
Thank you.

I just saw a tutorial in 4PDA by R0iz and wanted to share it here!

Extract the files *. img
To extract system.img, used unyaffs (http://code.google.com/p/unyaffs/)
I have compiled under Ubuntu 64. With Unyaffs can only be extracted system.img.
To extract boot.img use extract-kernel.pl and extract-ramdisk.pl
# extract-kernel.pl boot.img
# extract-ramdisk.pl boot.img

Rebuilding boot.img
After extracting boot.img with the enclosed extract-*. pl
In order to collect boot.img with Custom kernel in the same folder run:
# mkbootfs boot.img-ramdisk | gzip > ramdisk-boot
# mkbootimg --kernel boot.img-kernel --ramdisk ramdisk-boot --cmdline "no_console_suspend=1 console=null" -o newBoot.img --base 0x19200000

Rebuilding system.img
At first glance it seems that you can simply mount the image and format it with YAFFS, but it's not because, as SPL Hero does not allow flash system.img directly.
You must use the format update.zip packages for this. (читайте ниже) (See below)
Write update.zip quite simple really. For example, to add the package test.apk in your rum:
- Create an empty folder <workdir>
- Create a folder structure for test.apk (<workdir> / system / app) and copy test.apk
- Create a folder structure for the update-script (<workdir> / META-INF/com/google/android)
- Edit <workdir> / META-INF/com/google/android/update-script
- Insert the following:
show_progress 0.1 0 show_progress 0.1 0
copy_dir PACKAGE:system SYSTEM: copy_dir PACKAGE: system SYSTEM:
set_perm_recursive 0 0 0755 0644 SYSTEM:app set_perm_recursive 0 0 0755 0644 SYSTEM: app
show_progress 0.1 10 show_progress 0.1 10
- Pack the contents <workdir> in zip (not the folder itself <workdir>, only its contents)
Now you have to sign a zip file. Testsign.zip download and copy it to your <SDK> / tools.
Unzip it there, thus creating a sub-folder sign with a file testsign. in it.
Then in the folder <workdir>, run this command:
java-classpath "<SDK> / tools / sign / testsign.jar" testsign file.zip file-signed.zip
Everything is now ready for your update.zip pouring into the apparatus by a modified recovery.

Change. Apk package
apk can just unpack an archive, change what you need and pack it back. But in the end you have to sign it as well as update.zip packages.
ODEX files
- What is it? Answer
- How to get rid of them?
For deodex ODEX files, use this howto
Then you can create classes.dex file by running smali from your "out". Then rename it to classes.dex and add it to apk.
- How to create them?
Use dexopt-wrapper on the device.

Well, this part is simple smile_good.gif
- Extract system.img
- Extract boot.img
- Replace boot.img-kernel of the original Roma HTC Hero.
- Rebuild boot.img
- Collect update.zip (see how it's done in any Custom rum for Hero)
- Sign and flash.
Device should start, and even be able to call, but probably will not work WiFi, BT, trackball.
Androsign script (Linux)
Androsign allows you to quickly sign the zip and apk. Just put it in <SDK> / tools, then CHMOD + X. If the path to the folder \ tools registered in the PATH, then you can run this script by typing:
androsign /dev/folder1/folder2/update.zip
He will Update-signed.zip (or App-signed.apk, etc.) in the same folder where the original file.
THANKS ARE WELCOMED!
Can we actually use this to port Sense or MIUI ?
this explains part of the process, the steps to do fo that purpose extracting and rebuilding but of course not about the code. i've heard MIUI is complex than sense
Most of us know this allready but nice to see it being said instead of learning the hard way

this is how i did to fix md5 missmatch due to restore from feamod recovery
-firstly make a folder clockworkmod/backup/2011-12-16.12.56.43 IN INTERNAL SDCARD
open terminal emulator
type su
#cd / sdcard/clockworkmod/backup/2011-12-16.12.56.43
#rm nandroid .md5 (if u get this rm failed for nandroid. read-only file system just leave it)
#md5sum *img > nandroid.md5
reboot to recovery
restore from internal
Good idea to post that (used it too with some backups). If you can't get into your device (bootloop etc) you should be able to do it on your pc. I tried doing it with md5sum (see attached) but it then adds an extra x0D (carriage return)... so if someone knows how to do this, please add to this topic
Regards,
Nika.
Thnx. can be very usefull
I have ca. 3 archives where I get md5 mismatch only one is restorable. Only for understanding do I only create an empty folder and make this or must I use the backup folder from my backup ?
Thx in advance

Please explain what you mean. You have 3 backups that give you this error? Then you should go to each of those backup-folders and run "md5sum *img > nandroid.md5" (without the quotes off course). This will regenerate the md5 file and then the restore should work if the backup files are intact (I've had some backups with 0 kb files too)
..I tried and get "bad substitution"
Dontron
Edit: I renamed the folders and now I can use the command..give a try.

You want to do it automatically through ADB? Here's a script:
Code:
@echo off
set FixMD5backup=[COLOR=Red][B]/mnt/sdcard/clockworkmod/backup/011-12-16.12.56.43[/B][/COLOR]
echo cd %FixMD5backup% >FixMD5.adb
echo pwd >>FixMD5.adb
echo ls -l -a * >>FixMD5.adb
echo chmod 666 nandroid.md5 >>FixMD5.adb
echo rm nandroid.md5 >>FixMD5.adb
echo md5sum *img *tar ^>nandroid.md5 >>FixMD5.adb
echo ls -l -a * >>FixMD5.adb
echo cat nandroid.md5 >>FixMD5.adb
echo exit >>FixMD5.adb
adb -d shell <FixMD5.adb
del FixMD5.adb
pause
Make sure the path is correct

If you are using a back from your sdcard, you will need to mount r/w.
Here is what I did, and it worked perfect.
BETAlatform-tools akelly$ ./adb shell
# mount -o remount rw /sdcard
# cd sdcard/clockworkmod/backup/
# ls

For reference, attached is md5.exe and dos2unix.exe.
Here's the script to execute md5.exe (see attached) and make the nandroid.md5 on your pc:
Code:
@echo off
del nandroid.md5
for %%i in (boot.img,cache.ext4.tar,data.ext4.tar,recovery.img,system.ext4.tar,.android_secure.vfat.tar) do md5 %%i>>nandroid.md5 && echo %%i>>nandroid.md5
dos2unix nandroid.md5
pause
Btw, for everyone good to know, you can always run the md5sum from adb in clockworkmod recovery too (just before doing the backup, even when you're in the backup screen!):
Code:
adb shell
# cd /sdcard/clockworkmod/backup/[B]BACKUPDATE[/B]
# rm nandroid.md5
# md5sum *img >nandroid.md5
# exit

Nika.

Can you first check the filesize of each file that the backup created? If there's 0kb files you will not be able to restore them, do it with Advanced Restore one by one and you may be able to get back stuff...
If you don't know how to use the files I uploaded, I doubt a guide will help you

That does not seem like a complete backup. Normally you also have a system.ext4.tar, data.ext4.tar and cache.ext4.tar. I guess this backup failed.
The only things you have is a kernel (boot.img) and the recovery.

Right, I'd talk to the one that supports your cwm (touch recovery Lilg for Galaxy Mini)
I think I know already. Today, I had try backup and it's fine. Probably last time, I'm not use the proper method. Anyway, thanks for intention to help.

i am newbie
sorry for my question :
i have 03 clockworkmod backup in my ext_sd card named :
1 - 2012-05-08.16.48.10
2 - 2012-05-08.16.17.27
3 - 2012-05-02.02.25.41
i renamed them to :
1 - nitrox
2 - moon
3 - kqb
but when i try to restor i have md5 mismatch for all them
how to do for fix them all
please
EDIT : i finally understund the way :
i have moved clockworkmod from external_sd to sdcard
put the phone in usb debug
and than call adb shell with this :
adb shell
$ su
#
# cd /sdcard/clockworkmod/backup/nitrox
# rm nandroid.md5
# md5sum *img >nandroid.md5
# cd /sdcard/clockworkmod/backup/moon
# rm nandroid.md5
# md5sum *img >nandroid.md5
# cd /sdcard/clockworkmod/backup/kqb
# rm nandroid.md5
# md5sum *img >nandroid.md5
# exit
and then move back the clockworkmod to extrenal_sd and now all my backups work fine
thank you very much

Hello mates!
I've been playing with XT1097's boot.img and need some help as my boot.img fails to boot if I repack ramdisk.
Using abootimg
Extracting boot.img contents:
Code:
abootimg -x boot.img ==> produces bootimg.cfg, initrd.img and zImage files in the current directory
Updating boot.img contents without touching ramdisk (using the one extracted in the previous step):
Code:
abootimg -u boot.img -r initrd.img
If I extract initrd.img and try to repack it, then system fails at boot:
Extracting ramdisk (initrd.img) contents:
Code:
abootimg-unpack-initrd ==> produces a ramdisk subdir
Repacking without modyfing ramdisk folder contents:
Code:
abootimg-pack-initrd newramdisk.img
Updating boot.img with newramdisk.img
Code:
abootimg -u boot.img -r newramdisk.img
Even though the generated boot.img's size matches the original one - 10444800 bytes - system gets stuck at boot logo.
The same issue happens if I use these tools combined:
mkbootimg, unmkbootimg, gzip and cpio
Any ideas are welcome
