How to Unroot Galaxy S7 or S7 Edge with Stock Firmware!

If you ever screw up your Samsung Galaxy S7 or S7 Edge while rooting or installing custom ROMs, there’s an easy way to “unroot” and re-install stock firmware your phone came with.

There are situations where this can come in handy such as if you are going to re-sell it on eBay, return the phone for warranty, or want to simply update to the latest stock firmware on a rooted phone.

Now, this unroot method ERASES EVERYTHING ON YOUR PHONE! SO MAKE A BACKUP BACKUP BACKUP BEFORE FOLLOWING INSTRUCTIONS!  YOU HAVE BEEN WARNED!!!

Step 1. Go to Settings->About device and check the model number of your Galaxy S7 or S7 Edge and take a note of it, write it down somewhere.

Step 2. Power off your phone then hold down Volume Down, Center Home, and Power buttons together for about 5 seconds until you see a warning screen like below:

Step 3. Hit Volume Up key to put it into ODIN download mode then connect a micro-USB cable from your phone to your Windows computer.  We highly recommend you to use Windows but if you don’t have one/can’t borrow one, you can run Windows on top of VMWare instead.

Download:

Download ODIN

Download Samsung Galaxy S7 & S7 Edge Drivers for Windows

    My s7 hangs very frequently and I always get a notification of security and I tried to install knox counter but it said that it can not install because custom binary is installed. Android 6.0.1 and I bought the phone second hand please help me. It also failed to open many apps so when i restarted it it was stuck on boot screen so I had to factory reset it and now it hangs once in every 5 sec please help

  8. Sabbir ahmed says:

    Hey max, I can really use your advice. I rooted my s7 edge using the method you provided, and installing a custom rom which also you provided, before I carry on I would like to thank you for all that. But my phone seems to have a black dot at the edge of the screen/ faulty. If I unroot my phone with this method, will it get back my warranty? I’m confused as I heard you its got something to do with the knox…. I’m sorry but I’m new to the whole android.

  10. afsafs says:

    It failed… what do i do?

    • afsafs says:

      i got a newer version of odin3 and it doesn’t say failed now it just says setupconnection

      • Ruben says:

        Make sure you have installed the phone drivers.. Install samsung kies.. It comes with the drivers.. After installed reboot computer, then plug in your phone and let your computer recognize your phone(make sure it recognizes it).. After that try again.. If you still have problems make sure your using odin 3.12.3.. If it still hangs then use different usb port.. Or even different usb wire.

    • Bill says:

      Using Odin 3.12.3 with the 930T image provided in link fails similar to last 2 posters.

      • Bill says:

        I found another firmware that works. You need to match your build number in my case (G930TUVU3APG1) The boot screen still indicates customer (unlock pick) however and would like this completely back to factory.

  20. At says:

    Hi. I rooted my phone couple days ago. My device is SM-G935T (US T-mobile) I removed some of the system applications with out a back up file. And now I tried to unroot the phone I did everything as the webside shown. I have the latest Odin, but when I try to start flash the firmware it didn’t complete it keep failing. Now the root checker said the device is unroot, but I couldn’t get the Smartswitch to work. I don’t know what else I have to do.

    • Gabe says:

      I encountered this same problem, here’s what I did different to get a PASS
      Used Odin 3.12.3 Prince Comsy
      Downloaded firmware from another site (G935TUVU3APG1 instead of G935TUVU2APC8)
      While it did not get rid of the Android Custom logo, it did get my phone out of a soft brick after 3+ hours of research and failure.

  21. Daniel says:

  22. Ben Jones says:

    Do I need to uninstall twrp or anything else before doing this? If so, how do I do that please? Thanks.

  23. Brett Jacobsen says:

    Where can I get the stock firmware for model SM-G935A? Not having much luck finding that version.

  24. Martin says:

    Will unrooting with this method remove the customized android boot screen notification that shows when booting up the phone? I’m planning on unrooting to sell my phone experiencing extreme heat on my phone. I use my phone for driving Uber and it heats up in the middle of a drive and just stops working. Thank you.

  25. Alvin says:

    Please, can someone help me find the oficial rom for the Sprint Galaxy S7. I rooted the phone but is not working properly. I want to get it unroot.. I found some online, but when I try to unzip it, it always gives an error.

  26. Trent says:

    I’ve done everything step by step. Lastest version of Odin latest USB Drivers and Stock firmware. It just keeps failing. I don’t know what could possibly be wrong.

  27. Jimmy says:

    for those that fet “Failed” message using Odin, did you check ‘OEM Unlock’ ? and turn on USB Debugging in ‘Developer Options?
