[Resolved!]
1. there is no fonts directory in the system folder, resolve it by copying from other rom.
2. updater-script make a symlink from bash to sh, while there is no bash binary in my rom, so that adb shell doesn't work.
Hi, all,
My own rom can not bootup and hang at first screeen which only show 'HTC' boot logo. I don't know why and how to resolve this issue.
Target Model: HTC A310E with locked s-on
Origianl ROM: RUU_Pico_HTCCN_CHS_1.20.1400.7_Radio_10.34.80.09H_1.10.84.02_CHS_release_224342_signed.zip
I take the following steps:
1. unlock the target. (official unlock method)
2. flash CWM based recovery image (version: 5.x) via fastboot command.
3. copy boot_signed.img and system.img in the official ROM to ROM kitchen. (I changed the name of boot_signed.img to boot.img)
4. [Kitchen] unpack system.img
5. delete some third party apk under system/app
6. copy a updater-script from other ROM which works fine in my A310E and make slight changes.
7. [Kitchen] Build rom with default options.
8. double wipe and update my rom under recovery.
and then i encounter the bootup issue.
Please help give me some advice.
Thanks a lot!
Hi, I have new Prestigio tablet PMT5777_3G and I want to modify it's default ROM. I followed this tutorial: http://forum.xda-developers.com/showthread.php?t=1801690. I successfully extracted system folder, but I have no idea how to create updater-script for this specific ROM. If I understand correctly I need to get updater-script from original ROM.
I've got something that resembles original ROM, but it's folder structure is completely different from what I would expect.
I would expect:
META-INF
system
boot.img
I've got:
APDB_MT6582_S01_MAIN2.1_W10.24
boot-sign.img
BPLGUInfoCustomAppSrcP_MT6582_S00_MOLY_WR8_W1315_MD_WG_MP_V12_P4_1_wg_n
cache-sign.img
Checksum.ini
EBR1-sign
lk-sign.bin
logo-sign.bin
MBR-sign
MT6582_Android_scatter.txt
preloader_htt82_tb_jb5.bin
recovery-sign.img
secro-sign.img
system-sign.img
sro-lock-sign.img
sro-unlock-sign.img
userdata-sign.img
I'm an android developer, but have no experience with custom ROM's and now am in a situation, where I want to get that custom ROM up and running, but am unable, because I can't figure out how to create updater-script or extract it from files that I currently have. It would be great if someone could point me to the right direction of what to do next.
Thanks
P. S. It seems it's against the rules to ask questions here, but I can't seem to find where else to ask this on xda

Since you are a beginner to ROM development, I would recommend the use of dsixda's Android kitchen, which you probably have downloaded already. If not use this link
http://forum.xda-developers.com/showthread.php?t=633246
Follow these steps to obtain the file structure and Meta-Inf folder for your custom rom.
1. Open the folder where you have placed the kitchen.
2. You will find a folder called original_update.
3. Open that folder and copy your boot.img and system.img files into it. ( In your case it is boot-sign.img and system-sign.img. Rename those files into boot.img and system.img and place them in the folder )
4. Now open the kitchen. ( Refer the above link to know how to do it )
5. You will find " 1. Set up working folder from ROM " option under Main Menu.
6. Type 1 and you will be directed to another menu. Click Enter.
7. Select your boot.img and system.img from the menu.
8. Now follow the instructions that appear on the screen.
9. When you successfully complete the steps, you will have the required Working folder, with boot.img, system folder and Meta-Inf folder, which will contain the updater-script (It will be automatically generated)
All the best. :good:
Hit Thanks if this helped you... PM me if you need further help or search the forum for detailed instructions.
Thanks, this helped me, but I still can't create ROM.
I encountered a problem with kitchen:
Code:
Available ROMs:
(1) system.img and boot.img
Enter selection number (default=1, cancel=0, r=refresh):
Found original_update/system.img
Found original_update/boot.img
The new working folder will be named WORKING_061614_070841
Change the name (y/n)? (default: n):
Creating working folder WORKING_061614_070841 ...
Copying boot.img ...
Copying system.img ...
Adding an update-script ...
NON-YAFFS/NON-TAR FILE FORMAT DETECTED IN ROM
Mounting system.img to loopback device and then extracting files ...
Error: Unable to mount system.img
Error: No /system/framework folder found!
Press Enter to continue
This creates my missing update-script and boot.img, but system folder is empty.
Would it be a good idea to extract all system files from device and attempt to create ROM with them, and this update-script, or is there something I could do with system.img to make it extract?
Try this
Don't worry. There's always an alternative. Try this simple method.
1. Boot into CWM (Clockwork Mod) Recovery. (I'm pretty sure you know how to do it, if not, you can feel free to search the forum)
2. Choose Backup and Restore.
3. Make a backup in your external sdcard.
4. Now boot normally, open your external sdcard. You will find a folder called clockworkmod. Copy that folder to your PC.
5. Inside that folder, you will find the backup.
6. Now, copy boot.img and system.ext4.tar.a to your original_update folder of the kitchen.
7. Warning! Do not copy system.ext4.tar, only copy system.ext4.tar.a
8. Once you have copied these two files, rename system.ext4.tar.a into system.ext4.tar
9. Now, open android kitchen and follow the exact same steps as you did before.
10. When you choose the available rom, you will find the screen as below.
Code:
Available Roms:
(1) system.ext4.tar and boot.img
11. Choose it and follow the instructions. You will have your required working folder.
Try this and let me know if you still face any issues. :good:
I was unable to load CWM recovery, because it is not supported by my device. I tried TWRP too, which also doesn't support my device. Is it possible to do without CWM?

I'm sorry my friend, even if you create your own ROM, you require either one of them to flash the ROM to your device. Seeing you so keen on developing the rom, try to use any yaffs tool to create your system.img from extracted system folder. You may refer this thread.

hi,
for school I'm making a Windows program to unpack system.img, edit it, and repack it.
Is there anyone who know how to do this on windows? without an program? (especially repacking system.img)
I am now using ext4_unpacker and then ext2_explorer link: http://forum.xda-developers.com/showthread.php?t=2285831
this is the result: http://i.imgur.com/NJpDoCM.png
how to repack this? I prefer as system.img so I can flash it with adb, but if that is not possible I can also use my custom recovery (twrp or cwm) to flash it.
and I want to do this without a program, I prefer cmd commands.
(if it's possible to add all thos files to one zip file (update.zip) and then flash it in TWRP, that would be a solution, but is it possible?)
