Sprint SGS3 Stock Restore

This page describes how to restore your rooted stock ROM to a "Normal" unmodified state.  Use this procedure if you have previously flashed a custom kernel and/or recovery, and rooted by means of Team Epic's Root from Recovery, or similar.  This should allow you to successfully install OTA updates and will display "Normal" under About device -> Status -> Device status.  This method does not completely restore "Normal" status if you have applied other custom mods or further modified your System directory beyond basic rooting.

Supported Phones
This method only applies to the Sprint SGS3.

Disclaimer
We are not affiliated with Sprint or Samsung.  By using this software or following these instructions you run the risk of damaging your phone.  We are not responsible for what you to to your phone.


NOTE:  Do not use this method if you are already on LF9 or newer.  Updated instructions incoming.

Download (You need both files below.)
Instructions
  1. Copy TeamEpic-RemoveRoot-from-Recovery-signed.zip to your phone's internal storage.
  2. Boot into Recovery.
    • Power off.
    • Power on, immediately hold Volume Up, Home and Power buttons.  Let go when you see tiny blue text near the top of the screen.
  3. Flash TeamEpic-RemoveRoot-from-Recovery-signed.zip.
  4. Boot into Download Mode.
    • From recovery, choose "reboot system now"
    • Immediately hold Volume Down, Home, and Power buttons until the Warning message appears.  Press Volume Up to proceed.
  5. Run Odin in Windows, and plug the USB cable into phone and computer.  If your drivers are setup properly, Odin should recognize the phone by turning the COM box on the left blue with a message "Added!!"
  6. Click on PDA, select TeamEpic-Sprint-SGS3-stock-boot-and-recovery.tar.md5.
  7. Click Start to begin flashing.  If it succeeded the box on the left should turn green and say "PASS!"
Troubleshooting Odin
The #1 cause of Odin flash failures is a bad USB cable.  USB cables that come with phones are often not good enough.  It is hit or miss with retail USB cables, you might try two seemingly identical cables but only one consistently works.  Find a USB cable that works for Odin and stick with it.

  1. After I used this method, my youtube videos and the web show up upside down when I hold the phone sideways. Any ideas as to why this is?

  8. I unrooted my GS3 using this method and the phone state does appear as "normal," as well as having no more superuser, so it seems to have worked, but I cannot install OTA updates. After reboot for update, message states that process was aborted and I need to reboot from the recovery screen.

  11. I've been getting messages on my GS3 trying to push an android update (I'm assuming this is the Jelly Bean 4.1.1) but am hesitant to run the unroot described above due to the "NOTE: Do not use this method if you are already on LF9 or newer. Updated instructions incoming."

    my current build number is : IMM76D.L710VPALI3
    I'm assuming this is under the Newer category since I got my phone mid october and installed an update before rooting.

    Are my assumptions correct and if so, any ideas on when the unrooting instructions are to be updated?

    Thanks.

  19. just tried to unroot my phone using above method and when completed I get the samsung logo then just a blue to white flashing led. I tried to reroot the phone the phone using the teamepic method which I did before and the result is still a blue to white flashing led. I left the auto reboot and f reset time checked when unrooting but when trying to reroot I unchecked them as that was what the instructions stated. Any help would be appreciated. Phone is galaxy s3 sprint purchased at end of november 2012. Rooting it was successful about 4 months ago using odin3 and teamepic.

  20. FIXED
    Found stock rom for sprint galaxy s3 used odin to flash it to the phone from the laptop. ITR took awhile to download as it is over 700 mb and over 1 gb unziped. Did factory reset by wiping the data and cache and it works as if I bought it from sprint. Have to redownload my apps. When I connected to my gmail account from the phone all my contacts came back. Most of my pics and videos where on my flash card which I removed bofore doing the above process and thus are fine.

    1. congratulations! Wow, I thought we were just stuck since it's been a year since the last update from Team Epic. Can you provide a link to the stock rom you found and a list of instructions? I'm sure everyone else here would appreciate that very much!
