I have a sprint HTC One M7 that has TWRP 2.7.1.0a installed. It also has a screen lock installed from my work. I was trying to wipe the data and would up wiping all the data. I have rebooted into the recovery mode and have tried to load the ADB Sideload but it seems to go into an install loop and never completes. I tried to hook it up to my computer an the RUU script says there is no USB connection. When I try to reboot the phone it tells me there is no OS installed. Need help to see how to get the OS installed.
