I had rooted my device HTC One M8 (Sprint), and while attempting to flash the Venom ROM I deleted my stock OS as well as my backup. I am able to reboot into reboot into TWRP recovery and fast boot usb is recognized. However while attempting to use commands on terminal (Mac and PC) nothing is responsive. The only thing I can think of is trying to flash the stock Harmond ROM since there is no stock ROM for Sprint's regular M8 posted online yet. Another problem I have is to flash the Harmond ROM I would have to have S-Off, but unfortunately mine turned back on after I wiped everything. I was told by another person to side load a ROM but like I said commands are not working. I have also tried flashing from installing them on my external SD, but all the ROMS I have found require to have S-Off. Please help and tell me I am not completely screwed.
