If for some reason you don’t like your custom ROMs or you want to return your rooted Epic 4G Touch back to Sprint for warranty, here’s how to completely unroot your Epic 4G Touch.
Step 1. Put your Epic 4G Touch into download mode by holding down Volume Down and Power button together for about 5 seconds. When you see the Warning screen below, hit the Volume up button.
Step 2. When you see the download mode like below, don’t connect your USB cable yet.
Step 3. Download Epic4GTouchUnrootEL29.zip and unzip, you will find a file called SPH-D710.EL29_CL852097_ROOTED-OneClick.exe. Double-click on it to run the program, this will launch ODIN program.
Step 4. Now connect a USB cable from your Epic 4G Touch to your computer.
Step 5. Hit “Start” and your Epic 4G Touch will start to restore EL29 stock ROM.
Step 6. When it’s all finished (it should take like 20 minutes), your phone will reboot and you will still see that Superuser app is there. If you just want to use the stock rooted ROM, you can stop here. If you are going to return for warranty, let’s remove the Superuser app.
Step 7. Install ES File Explorer from the Market and launch the program.
Step 8. Under settings, make sure Root Explorer and Mount File System are both checked.
Step 9. Select Favorites, then “/”.
Step 10. Find the Superuser.apk file under /system/app directory and erase it.
Step 11. Now, let’s go one step further and reset your phone back to factory. Reboot into Android system recovery by holding down Volume down and Power button together for about 5 seconds.
Step 12. Choose “wipe data/factory reset” and hit the Power button.
Step 13. Choose “Yes”.
Step 14. Reboot your phone and you should find your Epic 4G Touch has been completely unrooted, personal settings/apps erased.
If you are going to return your Epic 4G Touch to Sprint for warranty, make sure you delete any personal files in the internal storage or microSD card beforehand as those are still there.Want to stay updated on latest Epic 4G Touch Root news?
