As of now I describe this build as a "massive hack".. samsung made this device very difficult to work with..
This build has NO AUDIO, NO BRIGHTNESS CONTROL, NO CAMERA.. and probably more! It is a "selinux permissive" "eng" build.
Sources will come in the next few days (a week?)(no ETA), I need to clean them up and fix audio first.
Flash it via TWRP if you're brave enough.
Thank you for this. My son has this tablet and I've been meaning to flash it for ages but hadn't realised how little development was being done for this till now. Eagerly awaiting your updates, you'll make the life of this father a lot easier!
