Sigh. i'm getting the same error as above^^ in rebooting to twrp. This happened before and one day it just magically worked. All I wanted to do was take out noozy and install sony walkman and now i've been up for 2 hours trying to reinstall this rom :/
Just fixed it. What I did was go to device manager and uninstall the HTC One XL driver which was listed as error with a yellow flashing sign. Then I unplugged the device, restarted the computer, then plugged my one x in so that my computer would re-detect it. it did, and then suddenly adb and fastboot also worked as well. well, hope this works for anyone else.
