Things often do when you don't deviate from the prescribed course of action and usage.
I say **** that, I'm doing what I want. Not sure if I can revert to a lollipop build, the Marshmallow build I'm using is official Google. I don't see a great deal different between it and Lollipop.
My phone isn't a Nexus device so it's got bloat. Currently have an AOSP rom on it. Basically Nexus like. I think I need some firmware updates prior to running a Lollipop build but I haven't found for certain.
Kinda fun, know what I mean?
Tablet is back up and running, I reflashed things and it came right up. I think I need to wait until there's a Marshmallow compatible TWRP available.
