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).

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).
