Instructions

At least MarshMallow bootloader is required or you will not be able to boot the rom !

Latest stock firmware is recommended before installing this rom, even if it might work with older versions !

You have to reboot one time after first boot to make mobile data work.

Use the TWRP from the download-link for your device above (needs to be flashed from existing TWRP, or use ODIN version)

Download the latest build

Put it on your device

Reboot to TWRP

Take a full backup

If you want to be sure wipe the device

Flash the latest build

Clean Cache and Dalvik if you want

Reboot and enjoy

Others

Easily rootable with the great Magisk (stable) by @topjohnwu.

I use it as daily driver without major issues, except mobile data (see above).

I use microG as google replacement and for push-services, signature-spoofing is already build into the rom but need to be enabled in "Settings -> DerpQuest -> More" and granted in microG-Settings or "Settings -> Apps & notifications -> Permission manager".
