So I was rooted with a stock JB rom, but randomly it decided that I didn't have root anymore. When I got home, i decided I'd just flash a new stock rom over it(it had some fixes to bugs I had in the previous rom) to try and fix the no root issue. After I did this, I had the boot loop of death, and the recovery(TWRP) couldn't mount the internal storage so I could nandroid restore. I then relocked the phone, and tried to run a 3.15 RUU and now the phone can only boot into the boot loader. Anyone know how to fix this?
