I have had my One plus X for a few months now. I have rooted it, but then decided I wanted the new updates, so I un-rooted it. I downloaded the new Oxygen OS update fine, I then attempted to install it. It said installation failed and rebooted into recovery mode. I have tried wiping the data and the cache, but can't get the phone back. Any help would be much appreciated, as I now don't have a phone until it is fixed. It would be great if I could just factory reset it and start over.
