I have an HTC One with S-OFF and GPE ROM, I'm trying to get pretty much everything back to stock now. I've identified my CID and downloaded the appropriate RUU exe, the drivers are installed properly and the device is recognized when I run adb devices. However, when I try the RUU it gives me error 170, and on the last step it shows this which is pretty weird "abd dfksfsafjsdfkklsj". Any ideas? Thanks.
Edit: It seems to give that error even when I don't have the phone plugged in at all:
