[QUESTION] How do I unlock HTC ONE M8 for Windows ??

Hello everyone,

As the title says…how do I unlock the ATT / TMOBILE HTC ONE M8 with WINDOWS OS with XTC2CLIP ??? I cant seem to get it to boot into a fastboot mode. How do I get this phone into fastboot mode?

Can someone please explain how to unlock this phone if at all possible?

Is it possible to flash android to remove the windows OS on this device?
