How to install the ROM
You have to use my Unoffical TWRP 3.3.1-0 Recovery to flash your device later. The file in the attachment is zipped and valid for the TWRP Recovery (don’t extract the rom zip!)
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!
