I have been crack flashing to find a nice rom that has no issues but end up with having to go with nougat. Don't get me wrong, nougat is nice and I can use Substratum for theming but you lose key features of the tablet because of hardware compatibility (camera for one) and ram management leaves much to be desired. I decided to go back to a 5.1.1 build but all the roms I finish throw me into a bootloop once I start installing the apps that I am used to running. I decided to try this rom and use the 3minit battery with it for some custom looks and man am I glad I did.
Flashed this rom, the latest 5.1.1 Open Gapps Pico zip and Magisk 15.1 and once booted, set up my apps and no bootloop. Everything is running great. I miss the themes of the other custom rom but at least I can use my tablet again, all of it, camera included. Nice work Dev.
