Follow this Galaxy S7 unroot tutorial if you want to restore the AT&T, T-Mobile, Verizon Wireless, Sprint, or US Cellular Galaxy S7 and Galaxy S7 Edge back to stock.
Early last week I detailed the step by step process to explain how to root the Galaxy S7 and S7 Edge from any of the major wireless networks in the United States (AT&T, T-Mobile, Verizon Wireless and Sprint). As with all major root modifications for Android, it’s always nice to have a backup plan in case something goes wrong, or if you simply do not like the changes that have been made to the device.
At the time, there wasn’t a collection of firmware files for these models but now there is. So for today’s tutorial, I will be going through this very Galaxy S7 unroot tutorial on my own Verizon Wireless Galaxy S7.
In the guide, I will also be including links for the Verizon Galaxy S7 Edge, along with download links for the AT&T, Sprint, T-Mobile and US Cellular Galaxy S7 and S7 Edge devices. So, you’ll just need to follow the tutorial as I do it, but just be sure to download the firmware files that match the specific Galaxy S7 or Galaxy S7 Edge that you currently own. If you get confused along the way, be sure to check the video as I will be doing the Galaxy S7 unroot right on camera.
Note – This will wipe all of the data you have on the Galaxy S7 and S7 Edge since it is completely reinstalling the software onto your device. Be sure to backup your important data with Samsung’s own Smart Switch PC software before you proceed.
Note – Some Galaxy S7 and Galaxy S7 Edge users report issues (a failed message within Odin) using the modified Odin file listed below (not all do though, so it’s likely best to try the modified version first). If this is the case for you, some people report that this version of Odin works for them, while others are saying this one works for them. The best idea is to try a different one if the one before it didn’t work for you (my Verizon S7 worked with the one linked in guide below but it doesn’t work for everyone).

Explanation
You probably already have the Samsung USB drivers installed (if you have previously rooted your device), so you won’t need to install them again if that is the case. You will need to download Odin (some people say they had to use the modified version, others, like myself, did this tutorial just fine with the regular v3.11 version of Odin that’s linked in the Note section above) to the PC and then extract its contents so you can launch the software and use it.
You’ll then need to download the Galaxy S7 or Galaxy S7 Edge firmware to your PC and then extract that as well. I have included both versions of the firmware (for the S7 and S7 Edge) in the guide above and for all major wireless carriers in the United States. If you have a different model, let me know in the comments below and I’ll do what I can to point you in the right direction. With those all downloaded, you can then boot the Galaxy S7 into Download Mode
Once you have the Galaxy S7 in Download Mode, you can then connect it to the PC with a micro USB cable. Now you’ll want to launch Odin and then load the individual files that you extracted from the firmware in step 6. There should be 5 files in here, but we only need 3 of them (AP, CP, CSC). You’ll see three files that start with the letters mentioned and that’s what we need to load into the AP, CP, and CSC section of Odin.
It can take a while for Odin to verify the MD5 has of the AP file because it’s so big (mine was 5GB). Simply wait through the process just like I did in the video above. With all three files loaded, you can then press the Start button in Odin and wait for the Galaxy S7 Unroot process to be completed, and then reinstall the Android software onto your device. You’ll notice your device rebooting twice after Odin is finished doing its thing.
The first reboot will take you into the Galaxy S7 Recovery Mode while the second reboot will take you back into the regular Android OS. From here, you’ll just need to set the Galaxy S7 or Galaxy S7 Edge back up and then connect to your Google/Samsung account so you can restore the data you previously backed up (or just start installing your apps).
Greetings. I loved the video and website. It’s clean and clear. Unfortunately though I could not finish the root. I tried both versions of Odin in the tutorial but no luck. I’m positive this is just what I need to fix my phone. but the following is from the LOG after failing:
Odin engine v(ID:3.1101)..
File analysis..
SetupConnection..
Complete(Write) operation failed.
All threads completed. (succeed 0 / failed 1)
any ideas or tips would be greatly appreciated!
I’m not sure what would cause this. Some have suggested to keep trying (that it’s a connection issue). Others have said to redownload the firmware and try again. Then some more people have suggested to try a different USB cable
AFter several fails I read this post and tried the original USB cable from Samsung. SUCCESS!!! Used original modified ODIN for US Cellular S7 with above firmware file.
That’s great to hear 🙂
I got the same thing
youre probably using the wrong version of the rom to flash. the version in this video is old, find the latest one
hey when i downloaded the firmware for the galaxy s7 edge verizon version it was only 2 gb and it only had the bl md5 file…
Did you extract the downloaded file like I mentioned in step 6?
I just downloaded the file for your device that is linked the tutorial and this was the contents. . .

I would suggest downloading it again
I get this and i am using the AT&T files with a AT&T s7 sm-g930a
I just added a 3rd version of Odin to the tutorial. If you had previously tried the other two that was linked, definitely check out the third one
i can only find two and im having the same thing wrong with my gs7e sm-G935A
I also have the same exact issue as ryan. Where is the 3rd version odin link?
The 1st version is in the numbered instructions, the 2nd & 3rd are in the paragraphed “Note” section just above that.
ok, i understand. I downloaded all 3 versions 3.12prince, 3.12.3, and 3.11.1 and they all don’t work for my att s7. I downloaded all versions of ATT G390A files ending PF2 and PH1. is it just stuck on root until a new update is available?
You could try those again and/or download other versions you find on the internet. In my case, I also enabled the “OEM Unlock” feature and “USB Debugging” in the Developer Options screen. Not sure if that’s necessary, but wouldn’t hurt. Best of luck!
Try using a different cable. i was getting this same error with at&t gs7 edge. I tried a different cable in a different port with odin 3.12 and i had success! 😀
Hey everyone, just to update, I found this link with pretty much the same instructions, but the ODIN version was different. To be safe I did download the stock firmware from this same link but did not do the BL file.

Other than that Thanks Android explain for the knowledge and video on how to do this!
Thanks for the feedback, Jimmy. I have updated the Note above the tutorial to let people know about this 3rd version of Odin.
Hello, i have the AT&T s7 sm-g930a. . .and i see that a firmware update was released on July 27, 2016. Can anyone confirm this process will still work? I read somewhere that Samsung devices prevent a “downgrade” in firmware, which seems to be what i ran into when trying this process with a firmware version i downloaded from another website.
Love the clarity of this article though, great job!
K. I downloaded the files to unroot my AT&T sm-g930a … but when I load it into Odin, both versions, Odin becomes unresponsive. This is only when I try to load the AP_G930AUCS2APF2_CL7617530_QB9897892_REV02_user_low_ship_MULTI_CERT.tar file. ALL the other files work. Help please. I don’t want to root my phone without having a for sure back up plan. Thank you
just give it a minute and it should load up the file
Please help!!! I tried to root my sprint s7 and it worked but I wanted to go back to stock. Ive tried 3 dirfferent versions of Odin and not a single one works. I keep getting “Complete(write) operation failed”
Please read all the comments, I believe all known resolutions are already posted. My recommendation to @len in the comments below was to: 1.) Enable the “OEM Unlock” feature and “USB Debugging” in the Developer Options screen, 2.) Try all three versions of Odin again, 3) Try other versions of Odin you find on the Internet.
Otherwise, find a wizard and pay them to help you – Best of Luck!!
hi I followed your steps above and when I clicked start on odin, it says FAIL model dismatch fail…. can you please help?
dismatch, or mismatch?
Hi-
I have a Sprint S7 Version G930PVPS4BQE1. Can you please direct me to where I can download the firmware? I rooted my phone to scrub some deleted photos and want to revert back to stock (battery life is terrible rooted) Thank you.
This is for the Sprint S7 – http://dl.psouza4.com/android/SMG930/SPT_G930PVPU2APF2.zip
Hi Doug,
My s7 edge is unlocked SM-G935F. Can you help me find the software to unroot my phone. I did not root it. I used a web site to restore some deleted text messages and it now has the device status as Custom.
Hi John,
It will depend on your location and carrier. You can find a database to search for here…

Thanks for the quick response. I’m in the USA. I bought the phone from B&H Photo. No idea what country it came from.
Found out that it came from Vietnam but this country is not listed on the link provided.
I want to try this, but I noticed that the firmware you have is a pretty old one. Do you recommend going with the one you have or downloading a more current firmware?
