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 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!

I used official firmware 7.0 (flashtool rom) and swapped recovery image with TWRP recovery image (just replace file in folder of official rom); this worked. Boot first to TWRP and flash this ROM.
"You have to use my Unoffical TWRP 3.3.1-0 Recovery to flash your device later." dont work
Working fine for me.
Great Job!
Only issue is that the system is using 28gb of my 29 available… so that is a negative thing.
Works like a charm. Thanks
It is not fine. Bluetooth doesn't work well : can't connect my Plantronics headphones and my Home -trainer whereas it worked fine with stock rom V26. Same problem with other variants (Lineage, CRDroid…) Please fix bluetooth.
