How to install the ROM

You have to use my Unoffical TWRP 3.3.1-0 (3.18.19) Recovery to flash your device later. The file in the attachment is zipped and valid for the Recovery (don't extract!)
Please backup NVRAM and IMEI with TWRP BEFORE flash! If you lose your MAC / IMEI after flash, you can restore it in 2 seconds!

First time installing the ROM
Boot into TWRP -> delete Dalvik, Cache, System and Data -> Install the ROM ZIP -> Install GAPPS  -> Restart your phone -> thats it!

Bugs and how you can fix it
