So, you want to unroot your HTC Evo 4G LTE?
If you just want to remove root, you can easily just use the SuperSU app and choose “Full unroot” under Settings. Now, this won’t remove “TAMPERED” sign in the bootloader, which shows up after rooting. But you don’t have to remove that sign unless you are returning your Evo 4G LTE to Sprint for warranty. If you are going to, then you can follow the instructions below on how to use RUU to unroot.
Also, if you don’t have custom Recovery installed, you don’t have to unroot to receive over-the-air OTA updates so long as you are on stock ROM. You might lose root though so just install RootKeeper app before doing so.
Step 1. First, you will want to make sure USB debugging is checked ON under Settings->Developer options.
Step 2. Connect your Evo 4G LTE to your computer and make sure USB connection is set to “Charge only”.
Step 3. You will notice that you have “TAMPERED” sign in bootloader.
Step 4. Go into Settings->About Phone -> Software Information and find the software version, mine says 1.13.651.1. Go ahead and download the same version of RUU.
Step 5. Make sure you have HTC Drivers installed, you should see “My HTC” or “Android ADB” in Device Manager.
If you have “Android 1.0” with exclamation mark, manually update the drivers using appropriate Windows drivers below:
Step 6. Simply run the RUU exe file and DON’T RUN ANY SOFTWARE ON YOURCOMPUTER WHILE DOING THIS!
Step 7. After about 20 minutes your phone should be unrooted. Now, there are times where your drivers might need to be updated manually so keep Device Manager open and update drivers manually if your driver goes back to Android 1.0.
Step 8. If you reboot into bootloader after unrooting, you will find the tampered sign gone and “LOCKED” shown.
Congratulations! Now you can take your HTC Evo 4G LTE back for warranty if needed and there’s no trace of rooting.
