In this guide, we show you how to restore stock firmware on HTC 10 and unroot it. Custom recovery and root access on HTC 10 give users vast opportunities, like installing custom ROM, adding new features, removing useless system apps, etc. but sometimes users run into problems after rooting and flashing custom ROMs and want to return to HTC’s stock firmware on it.
