HTC One M8 Softbricked and Unable to Flash



Hi, A friend gave me a Verizon HTC One M8 that was softbricked by a failed attempt to root or modify the device. I am unable to find out what the original owner did to the phone.

The phone will get stuck on the HTC logo for approximately two minutes and then reboot. I can get into the bootloader no problem, but the recovery and the factory wipe options go to the HTC logo and then get stuck at a black screen with the backlight on for approximately two minutes before rebooting. The command "fastboot oem rebootRUU" goes to the same HTC logo for approximately two minutes before rebooting, fastboot is unable to see the phone in this mode.

Because the bootloader is locked and cannot be unlocked because it is a Verizon, and the phone is S-ON, I am unsure how to fix the phone.

I have attempted to use RUU from a microsd card numerous times with the RUU images from here: http://forum.xda-developers.com/veri...605-2-t2883845. the 4.4.4 one appears to complete successfully, but still bootloops after restarting.

Thank you in advance for your help.
