[Galaxy S 4 Q&A, Help & Troubleshooting] ww2916269:
Hi everyone,

Need for you help and thank you very very much.

I am trying to learn to make a custom rom for i9502 but I met a problem.

I download offical CMG2 firmware and get the system.img and cache.img(for csc files), I forked kitchen git and patch it to support 9502(maybe not succeed...)

I made common stuff in kitchen like Root init.d deodex zipalign, disable startup sound and enable data app support, then build up the rom with kitchen.

But when I flash this rom, my phone fail to startup. It go to totally black(I am not sure black or just not boot) after the china unicom logo showed. I tried to wipe and flash other roms and my phone startup right, so I am sure it's the problem of my custom rom.

I can't make the adb logcat because it's just too fast to go black. Do you have any idea about this problem?

BTW:

after I flash that rom, when I try to reboot from the recovery(phliz recovery for i9500), there is not an warning for "disable offical recovery recover" nor "root".

I used the offical boot.img for the offical rom and unoffical recovery from phliz.

I attach my last failed updater-script as blew (I just use kitchen to build up the uncompressed offical rom without any other operation as root, deodex..etc).
