I have the g620s device and I'm looking for a way to update the system without wipe everything (unlocked bootloader, root and CWM).

Following you guide to have system.img and receovery.img

starting from the g620s update.app, could be dangerous for my device?

9. It's okay the ROM is extracted where you have choosen !!

I hope this guide will be helpful!! And don't forget to thanks Galaxy Please can you help.

After running the split_updata.pl file, I immediately get a

system.img file in the output folder The file size is 18 528KB.

Then after running the HuaweiFinder.bat file, the output file

shows two system files. The original one (18 528KB) is named system.img.img and there is also a second file named system.img with a size of 47 162KB.

WHICH FILE IS THE CORRECT SYSTEM IMAGE? Also, when executing the HuaweiFinder.bat file, no boot.img or recovery.img is found?

PLEASE CAN YOU ADVISE. http://forum.xda­developers.com/showthread.php?p=58116339#post58116339
