I have an HTC one M8 and have gone through the trouble to convert it to a STOCK unrooted GPE. The phone has worked flawlessly for about 3 months. One day I wake up and see that my phone is stuck in fastboot mode. I've tried various things such as trying to reflash it to stock HTC Sense and attempted to add TWRP but no luck. Everything that I attempt to do ADB and Flashboot wise tends to FAIL. I think because after I flashed the rom to STOCK unrooted GPE I never allowed the USB debugging. My phone cannot mount to my computer despite the many times I uninstall the device and reinstall it. Can anyone help me? I'd atleast have it brick to wear it wouldnt load fastboot so I could bring it to AT&T without them questioning why my phone is UNLOCKED.
