first of all,it may be helpful to know what carrier variant you have... i imagine all the gsm versions are compatible,but if youre sprint,youll want to be careful what images you use.
unfortunately,i have no adb deamon running either. i botoed twrp 18.104.22.168 on my one x,and could not find an "adb enable" or such option.
first,check in the "mount" section... there should be a button to "mount usb storage" wich will allow you to to simply drag and drop a rom to your sd on the PC.
failing that,under advanced,there are options for adb sideload,and terminal commands(doesnt enable adb onthe PC) so possibly the former could be of some use,or maybe the terminal option could be used to "adb pull" someting from the PC
failing all that,you could try clockwork recovery,wich in my experience is always useable with adb,but again,we need to know what variant you have
