I have an unrooted HTC Sensation 4G from T-Mobile. I've done several factory resets, from bootloader, settings, and functions, and each time I do, I still don't get a complete reset. Right before it shuts off, I catch a glimpse of a popup in the middle of the screen that says something about "reverse action...." And I don't get to read it all. I believe there is some type of spy program that is not letting me do a factory reset. Also, after the phone turns back on, before I enter any personal data, it already has my gmail programmed and my contacts loaded. I've contacted HTC, and they can do a full system wipe for $85, and I have to be without my phone for the duration. Is there any way that I can do this myself? Someone please help!
