Have you rooted your Samsung Galaxy S4 and modified it? or installed a custom rom? and now looking for a way to get rid of the root access and get back to the Factory state / stock firmware? Well, sometimes the root access becomes a pain in vein, specially when you have flashed mods or custom roms along with the root access and you want to get rid of it as soon as you can. Following the need, We will be having a look on how we can unroot the Samung Galaxy S4 and get back to the factory state. You just need to follow the steps explained below to the letter.
To unroot your Samsung Galaxy S4, you need to flash a stock firmware / rom on your phone, this will unroot and remove all the junk from your phone as you will remove the factory data after completing the flashing process. So before we begin, you need to backup all the important data placed on your phone’s internal storage, contacts, call logs and messages. Also make sure that you have battery charged over at least 60%.
Please keep in mind that flashing a stock firmware following the above method will not get your device’s warranty back as it does not erase the binary counter. It is possible to gain the warranty back on Galaxy S4 GT-I9505 using Tirangle Away app, but the app doesn’t work on other variants due to the restrictions by Samsung. The method explained above is basically for unrooting your phone and getting it back to the factory state (as it comes out of the box).
We hope that the above method helped you. In case you face any problems, feel free to write us. We will try our best to help you out. Thank You!

Thank you thank you thank you! After a bad experience with CyanogenMod, this COMPLETELY saved my phone! Thank you so much!
@disqus_6wjLV2yyKb:disqus that's great. Thanks for your feedback. Stay connected with us.
Must be with something with CyanogenMod as my phone has stopped working correctly. So I am following your instructions above and so far so good. Thanks for help
@gavinmcsherry:disqus good luck :) It definitely will work.
One question how long does it take the phone to reboot as it has been sitting for 10m mins + with Samsung logo flashing on and off the firmware finished uploading and odin says it passed. I am at the stage where the phone is rebooting before I pull the battery. Any ideas. Thanks
Something is definitely wrong the phone is not rebooting it is hanging on the Samsung Flashing logo. Please help. Thanks
Usama something has gone wrong. I now tries it 3 times and gets to the same step and seems to hang. After removing the battery, waiting for 30 secs, replacing the battery and holding the home, volume up and the power button the phone restarts and goes as far as the Samsung Flashing logo and seems to hang. I have followed your instructions above but I am struggling to get any further. Please help.Thanks
@gavinmcsherry:disqus how long its been since its hanging on the boot screen? Just boot into recovery and wipe your phone.
and try booting it up, if it still doesn't boot up, then wipe your phone once again and flash new firmware after wiping. It will definitely work.
Thanks I finally got it to work. I discovered I was holding the volume up, home and power buttons to long. I tried it again and let them go immediately after the phone vibrated turning on and it went into recovery mode and Wiped / Reset Factory Data and Cache and all is good now. Just a little heavy handed on holding the buttons. In the middle of restoring my back ups. Thanks once again.
@gavinmcsherry:disqus that's great. Stay connected with us :)
Usama my phone is not entering recovery mode after pulling the battery and waiting 30 secs and the holding down volume up, Home and the power buttons. What I do now to fix this issue. Thanks
@gavinmcsherry:disqus just wipe your phone completely (factory reset) and see if it boots up or not.
@gavinmcsherry:disqus that means the firmware hasn't been flashed properly, flash it properly first.
Why is it every post I put asking for help keeps disappearing?
@gavinmcsherry:disqus nothing is disappearing, it appears once its approved. I've got all of your queries.
