*Updated November 25th – Sprint Hero Support. Download and use the Sprint Hero RUU instead of the Original RUU.
Here is how to get back to the original Hero ROM. You can use this to unroot for warranty purposes OR you can use this if you have the latest Hero ROM (which blocks rooting) and want to downgrade so you can root and re upgrade.
1. Download the follow file and save it to your computer:
2. Download HTC Sync and install it on your computer (if you haven’t already). You can download it from HTC here:
3. Plug in the phone to the computer via USB cable (HTC Sync should be running and automatically connect to the device).
4. Once HTC is done syncing, double click the RUU file and follow the onscreen instructions.
5. That’s it!
Now if you want to root your phone again, just search our site for Hero Root and do that procedure and then the How To Load a Custom ROM one as well.
