Removing demo software on HTC One M8
I got a demo unit (HTC One M8) through work. I have tried to restore this to work as a normal phone, but I was unable to do so. There is an app called Demo that I cant uninstall. The Developer mode can't be touched but USB debugging mode is on (when I connect it to my PC). I can't do a factory reset as the OK button is greyed out.
Any tips would be greatly appreciated
