Htc one stuck in viperone 1.2.1 Ota installer
I am completely new to rooting and flashing roms, I don't know anything about this so i will need detailed instructions, my phone is stuck in the installation wizard for viperone Ota 1.2.1, how do I get back to twrp recovery? I tried holding the volume down button and the power button, and all that happends is the home and back buttons flash. What do I do to fix this? Is my phone permanently bricked?
also, in the installer it has a progress bar on the bottom, it has stayed on 0% for over 30 min
