edit system.img

trapacska · Dec 23, 2010

hy everybody.

i try mod the system.img on ubuntu linux with unyaffs and mkfs.yaffs2, i "hacked" the symlinks(because the armv6 unyaffs doen't like) so now everything is ok, unyaffs works well. BUT:

when i flash the other sin files with flashtool, my x8 is restart after a green sony ball. i gave to all file in bin folder: rwx-rx-rx and the all other files got rw-r-r permissions.

so, i don't know what is the problem with this method.

//my system.img was flashed with a method in "clean and pre-rooted 2.1 rom" thread.//

in attachment the files

unyaffs and mkfs.yaffs2.x86)

unfortunately unyaffs-x86 does NOT preserve all file permissions if image is extracted and reassembled in Linux x86.
You have to extract/assemble on the phone to keep permissions.
Or, alternatively, you can fix permissions by using xRecovery tool, there's a menu "fix permissions".
To see why exactly your phone reboots, use adb logcat from PC.

i've created sh script to view your current permissions.
it could be useful to re-set the permission manually to create the ROM
how:
upload to root of sdcard
run

Code:

su
cd /sdcard
sh plist.sh

it will create folder "permissions" on your sdcard.
all files permission listed there

open with notepad++

you know what. i've found a better method to change permissions

1-mount original system.img

Code:

mkdir tmp/1
sudo mount -o loop /your/system.img/path /tmp/1

2-clone permissions from original system.img to your system folder

Code:

chmod -R --reference /tmp/1 /your/new/system/path

and the permission fix done!

EDIT: tested. and worked. I've finally created my own modified ROM

(running on sdcard)
EDIT2: some problem with root permissions, will work on it

thank you

i found a way to fix permissions too:

1. unyaffs original system.img
2. in busybox shell mount it to r/w
3. copy xrecovery and su and superuser to fresh rom.

(for me it works well without xrecovery fix permissions)
if there is some error, you can fix it with xrecovery

Hello,

Can you try to change the /system image with one from froyo ? You can find such image in the X10 forum. I thing that if we change the contents of the /system with such from froyo it should work. With the standard kernel from eclair.

Please try this and let me know.
