I have an international HTC ONE M8 which I managed to root and s-off without a problem. However since I s-off-ed the phone will not reboot into bootloader.
When I try to power off and reboot with vol-down and power it either reboots or flashes between the battery screen and TWRP, which say swipe to unlock but it flashes too quick for mee to do this. This a strange error I never come across before in the years Ive been flashing and modding devices.
Also ADB no longer sees this phone in fastboot, I can issue fastboot commands but not ADB
Can anyone help
