i have been having some problems flashing roms. i keep getting errors. i tried the latest pacman rom and dirty unicorns rom and both have an error. so i tried updating to the newest twrp recovery. and going down one version as well to see if it would help. anyways now i am stuck in recovery, my touch screen wont work, and twrp has a screen lock that i cant get out of because i cant slide the slider since my touch screen wont work. how do i get back to boot loader so i can flash another version of the recovery so i can get my phone back!!! help!
