I just went back to Stock KitKat, took the new OTA (T-Mobile) and rooted with towelroot. Everything went fine. When I was removing some bloat and restarted I get the LG Boot Logo and a Security Error underneath it. I cannot get into the Bootloader at all. Holding volume up and plugging in the usb cable does nothing. I can, however, get into stock recovery and wipe but that doesn't fix anything. Does anyone have any idea how to get out of this soft brick?
