Recently my device was prompted with an update alert for 7.0, after the update for some reason my touch screen no longer functions at all. I searched a bit and people said it was due to a replacement screen " which I have" so i attempted to downgrade back to 6.0.1. The thing is I have tried at least 3 firmware and none have seem to work yet all of them giving me a fail after cm.bin. TWRP does not work either because of FRP which I cant even disable because of the screen not working. Can someone please help me im extremely desperate.
