Did you just root your Samsung Galaxy S3 and are not comfortable with a rooted phone? Are you tired of flashing custom ROMs and want to go back to stock ROM? Do you want to update your phone directly through the OTA updater like you used to before rooting your phone? If you answered yes, then continue reading to find out how you can unroot Samsung Galaxy S3.
The Galaxy S3 might be really old, but it is still a great Android smartphone even without root access. However, rooting can make Android devices a lot more awesome.
If you feel that rooting didn’t bring any benefits to your Galaxy S3, then you might be interested in reading about the 10 best ROMs for Galaxy S3 before finalizing your decision on unrooting the device.
Why Unroot Galaxy S3?
You’ll find many guides on rooting the Galaxy S3 along with the benefits of rooting, but you won’t find many benefits for unrooting the phone. That being said, unrooting does have some advantages.
- Send your phone for repairs under warranty. If you send your phone to Samsung in order to claim warranty, they’ll refuse to repair your phone if it’s rooted or if there is a custom ROM installed. Unrooting alone will not fix it and you’ll have to reset the flash counter. I’ll show you the steps for resetting the flash counter in this guide as well.
- Sell your phone to someone else. If the buyer of your phone finds out that you rooted your phone or if the phone doesn’t have its original firmware, he/she may refuse to buy it.
- Install regular Over The Air updates. Once you’re unrooted and back on stock ROM, you’ll be able to install OTA updates like you used to before rooting your phone.
What You Need To Do Before Unrooting Your Samsung Galaxy S3
Resetting the flash counter and unrooting the phone are both risky processes which is why you should only attempt them at your own responsibility. If you’ve made up your mind to unroot Galaxy S3, then follow the tips mentioned below.
- Charge your Samsung Galaxy S3 at least 70% in order to avoid your phone running out of power during the unrooting process.
- Backup your phone. Feel free to read our list of the best backup apps for Android.
- Sync your Galaxy S3 with your Google account so that you can get some of your data back when logging into your Google account after unrooting the device.
How To Reset The Flash Counter
This is an optional process before unrooting your Galaxy S3. This basically resets your flash counter. If you’ve flashed custom firmwares on your Galaxy S3 and you want to send it for repairs under warranty, then you’ll need to reset the flash counter.
Step 1 – Download Triangle Away
Go to this XDA forum thread and download the TraingleAway APK file from Attached Files. Also, make sure that your Galaxy S3 variant or model number is supported from the Supported devices list in the same thread. The app is also available on the Google Play Store, but it costs $2.49.
Step 2 – Transfer The APK File To Your Phone
Once you’ve downloaded the APK file, transfer it to your phone.
Step 3 – Enable Unknown Sources
Go to Security in Settings and enable the Unknown sources option.
Step 4 – Install The App On Your Galaxy S3
Go to your file manager and install the TriangleAway APK file.

Step 6 – Press Reset Flash Counter
Once the download process is complete, tap on Reset flash counter and press the Continue button.
Step 7 – Reset The Flash Counter On Your Galaxy S3
Your phone will now boot into a new screen with a Triangle warning sign. Press the Volume Up button once to reset the flash counter. Your phone will now reboot. That’s it!

Could you please rephrase your question, I don´t understand, thanks. =-)
David Mercer on
I had rooted my s3 but did not install a different os. I performed your unroot instructions and everything seemed to work. Custom Binary Download: No, Current Binary : Samsung Official, System Status: Official . However nothing else changed. Triangle away is still there and Astro & Root Explorer still work. Also Kies does not work with my phone,SCH-R530U, tried 2.6 & 3. Any thoughts on why?
on
Hi David,
Root explorer and Astro will of course still work, they are file explorers. They just won’t have root privileges. But the proper unroot for most Samsung phones is to download the most recent stock .tar for your specific model and flash using Odin with a PC. If you did that, then it is no longer rooted. If that app (triangle away) is still there, uninstall it. Hope this helps. Thanks for commenting. =-)

hey I just want to ask how long is “a while” (the last reboot)….because i am waiting an hour already and it is still rebooting
on
Hi Lulu,
Have you tried a factory reset? =-)
shafi on
what is your suggestion about if I do factory resetting to un root my s3 device.
on
Hi Shafi,
No, a factory reset won’t unroot state of your phone. You should still have 1) the custom recovery partition installed, 2) the su program, and 3) the SuperUser app, and 4) whatever custom ROM you installed (unless you did an in-place root). Have you tried any of the methods above? =-)
Groover on
Hi
I followed all your steps and my S3 rebooted but is stuck on the SAMSUNG screen. What now?
on
How long did it stay stuck on the Samsung screen?
jyan on
Same here…after ODIN says pass but i’m stuck with SAMSUNG screen…
on
boot the phone into recovery mode by holding down Volume Up, Power and Home until the boot logo of the phone would appear. This starts the recovery mode. Run the following two commands (using Volume up and down to navigate and power to select):
Wipe data / factory reset
Wipe cache partition
After that select reboot.
Kevin on
Hey, I made sure I followed all the steps but I’m getting a “FAIL” response. I have a SGH-I747 model. Any suggestions on how to fix this? Thank you!!!!
on
Hi Kevin,
Do you get this at the end or during the unrooting process? =-)
Justina on
I tried to follow your instructions, but msgBox shows and says that: triangle away could not locate hidden partition. Are you not running ICS? So, i have a question: what to do to make this work?
on
What variant of the S3 do you have and what Android version?
IskandarMahazir on
Hai there, what if the ODIN says ”reset” instead of pass, can it consider as ”pass”?
on
Try rebooting phone and then remove the phone from the USB cables.

Nice Post Tho’..I Have Been Having Network Problem Ever Since A Friend Of Mine Rooted My Phone. .Will The ” Unroot ” Process Fix It Or….It’s Just Something Else? ..Just Wondering.
on
did you just root it or did you change the ROM or change settings too? Rooting, in itself wont really change much. It mostly unlocks the access to the root of the system. You can definitely try the unroot if you didn’t flash a new ROM. it should be pretty straightforward.
