Hi, I've been reading this topic and some others for hours and still cannot find a solution. I bought the G300 two weeks ago, rooted it and installed recovery. Also did IMEI backup and stock rom backup. After that I installed AtomicMod, and later I installed lishuo-B897, but I wasn't happy with it so I restored my backup and then I installed a B894 rom I found. All that I did without problems and used the B894 for a week.
Now I wanted to update to B926 so I followed the instructions on this guide, but the update process stops right after unpacking and I get "update error". I tried several times, always with the same result, so I tried to restore my stock backup. After reboot the phone would stay in the boot logo, and then go to recovery with a message saying there was some error with a command. I wiped data and cache, removed the battery and then it finally booted. The weird thing is that after the restore I don't have the original boot logo and animated splash screen, so something is not right. The vendor package is missing, as I don't see the toggles in the notification area. What should I do? Is there any thread I am missing? Any help is much appreciated.
