I'm am not responsible for bricked devices, flashing custom ROM's/Recovery's is done so at YOUR OWN RISK!
I recommend doing a full wipe before flashing!
Flash ROM using TWRP
Flash GAPPS 7.1 arm package of your choice
Reboot & wait for Android to boot
For root access flash the addonsu-14.1-arm-signed.zip available from https://download.lineageos.org/extras
ROM OS 7.1.2 Nougat
ROM Kernel 3.10.107
Thanks goes out to @wbrambley for his involvement in testing & helping to solve / fix bugs!
