I HAD Twrp recover... Had CWM recovery... phones acting like it doesn't have custom recovery (pain in my ass.)..... thought i used rom manger to put cwm back on it.
IDK the modem
I was on a Slim ROM (which was giving me problem as well; Great Rom but it just recently kept crashing.)
I already tripped knox forsure ..... and dont care..... i wanted to get it on a stock kernel by unrooting (Wasnt as brillant as I thought)
Don't even know if thats it possible (If it is show me the promise land!
I wanted root again so I could get triangle away working on root.
However that is how I got here. So getting my phone operational would be a win, start; challenge accepted!
