[Q] I think I bricked my phone - T-Mobile HTC One (M7)

While trying to get S-Off on about every method I could, and reflashing RUU. I think I bricked it.
What happened was that I attempted to relock the phone. (fastboot oem lock), so I could reflash back to stock.
I'd done this already without any issues. But this time, when I did, it got stuck on booting to the boot loader. It wouldn't boot into recovery nor into the ROM. After about an hour, I finally got it to boot again. However, The only way I could do this was to flash the unlock token.
The issue here is now that when it boots into the fastboot bootloader, it shows some graphical issues and refuse to take the RUU, even when manually flashing it.

The phone is currently on Android 4.4.2, Sense 5.5, stock.
The RUU I'm using is:
RUU_M7_UL_JB43_SENSE50_MR_TMOUS_3.24.531.3_Radio_4A.21.3263.03_10.38m.1157.04_release_336982_signed_2(2)
I have the OTA zip for 4.4.2, as well as the firmware.zip from it.
None of it works, and all errors up with the above error.
And no, I don't have S-Off.
Additionally, when connecting to fasboot USB, it does some screen tearing, distorting the text. I suspect that I've damaged the firmware and the phone is basically a brick. It does boot, but I cannot reflash the RUU.
