No OS, HTC One m7? Help!

[Jonnyswboy]

have an HTC One m7 with Hboot 1.57. It's unlocked with TWRP recovery. When I try to boot into system it just goes back into recovery! I want to get back into stock Sense 5.5 or CM11. Either one works. I'm kind of a noob, how would I do this? Do I need S-Off to sideload the CM11 ROM? I can't access storage on the phone and have no micro-sd card.
