I purchased a ATT HTC One from one of my friends, it was rooted and had TWRP installed. It was also running Bigxie 4.3 GPe rom. I would like to go to the GPe 4.4 rom but the problem im having is all they ones I can find say they require S-OFF. My phone is S-ON and I have not been able to obtain S-OFF with revone or rumrunner. I tried moonshine but my phone would not boot after the fastboot process. Revone gives me an error 1 and rumrunner tells me to flash a unsecure kernal and try again. The phone is hboot 1.44. After doing a little research I found that someone pleople are saying to go back to the factory rom, the problem is im not sure if the guy backed up the factory rom before he flashed the 4.3 GPe rom. I have asked him and he can remember and blew me off... so my question is how can I find out if he backed up the factory rom, how to restore it or how to obtain S-OFF with bigxie 4.3 GPe rom. Thanks in advance for the help, btw im a noob at this so the more dumbed down responses the better
