If you ever screw up your HTC 10, perhaps end up in a nasty bootloop, lose radio while rooting, or simply want to return your HTC 10 back to 100% stock software, there’s an easy way to do it.
Now, this will work on any HTC 10 so long as you have the correct RUU. As of writing this post, there’s only RUU out for the unlocked version of HTC 10, which should work on all GSM versions of HTC 10.
Unrooting/unbricking will ERASE EVERYTHING on your phone so MAKE A BACKUP of everything before preceding!
Please check out HTC 10 Stock Firmware/RUU page to see if your model of HTC 10 is supported.
*Note – For this unroot/unbrick method, you WILL NEED Windows computer (or run Windows using VMWare on Mac or Linux/Ubuntu).
Step 1. Go ahead and press down on Volume Down and Power buttons for about 30 seconds until your phone reboots and you see HTC logo like below:
Step 2. Once in HTC download mode, connect a USB Type C cable from your phone to computer.
Step 3. Download HTC 10 drivers and the RUU for your model of HTC 10.
Make sure to run the HTC 10 drivers program (double-click) to install drivers. If you have installed the drivers correctly, you will see either “My HTC” or “Android ADB Interface” in Device Manager.
Step 4. Run the RUU program by double-clicking on it.
