[Q] HTC One M8 Fastboot Loop

Hi XDA,
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.

[Q] Phone keeps rebooting after root attempt

I got this phone from a guy who didn't really know what he was doing. He attempted to root and now it will boot to the stock rom, and after a few minutes, it'll reboot. Trying to go into the SuperSU app will cause an immediate reboot.
I'm not familiar with HTC phones but here's what I get when I boot to HBOOT.

There is TWRP on here and going into it once has made the phone switch between it and the normal battery screen it has when it's powered down and charging. I also get a warning that "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may lead to legal action."
How can I get this to working order? I plan on getting it to stock and then rooting it and putting it on the GPE rom to get Lollipop.

Fastboot USB is enabled. Not a clue how to solve this if you would help me would be highly appreciated.
Google and follow an online guide on unlocking HTC bootloaders.
They literally made it extremely simple, there's no need for hacks, it's fully supported by HTC itself.
If you want more specific guides for your device check this out:

Is custom recovery TWRP installed?
Did you wipe "system" within TWRP?
My recommendation would be to RUU back to full stock. Which will also properly update the firmware, which looks like it was not proper done; which is why OS number is red, and also that number (indicates Lollipop firmware - but red indicates there is an issue) does not correspond with the radio number (Kitkat radio).
If any actions are suggested after RUU, depends on whether you prefer to stay on stock, or want to flash Viper back onto the phone.

Can't start the phone into a ROM

Hello,
I got TWRP on my phone, wich was running on marshmallow. I unlocked the boatloader but when i tried to flash a rom, the phone kept rebooting without launching the rom. I'm actually in a dire need of help. I actually just want my phone to work again.
Aswell, i would like to know if i can flash a stock rom 5.0 lollipop on my phone and then flash a custom rom in 5.0 ?
