I had Cynogenmod on my device* So a while ago my Samsung Galaxy Tab Pro 8.4 started acting up and crashing when it would get below 65% ish. Recently when I would turn it back on, a message would come up saying my device was unstable and that I should Factory Data Reset it. I already had TWRP on my tablet, but after I reset the thing, TWRP is no where to be found. Even when I hold down Volume Up + Power + Home, it still wont boot into TWRP like it always used to. So now I'm stuck without an os and am not sure how to get one back on there. Any help? I'm very good with mobile devices (android especially) so throw anything you got at me. I need help though.
