M7_UL is bricked

Hi, I recently bought an M7 which is bricked believing that I can fix it and profit. It boots into fastboot and recovery (although recovery is a piss off to get into) just fine. The bootloader is locked. So when I saw it I tried to do a factory reset through the recovery, but I noticed that it said something like a backup that was already there. So I decided that the best option is to unlock the bootloader, so I went ahead and opened HTC Dev and opened fastboot until I noticed that it wont connect to the computer. I tried a different pc different usb, different port, but no luck. Adb and fastboot wont connect. I checked whether it was the usb port. It charged with no issues whatsoever. So this is definitely a software issue. Does anyone know a way to fix this? I am experienced with the m7 so any advice will help. And yeah I tried to re install the drivers as well. Thanks.
