How To Unroot Samsung Galaxy S6

Galaxy S6 is on the roll now. Its mighty specifications, cool design, a solid build and mesmerising features make it worth having. If you are planning to get your hands on this device, I’m pretty sure that you won’t be able to resist yourself from going out of the boundaries and checkout what your device has got or what’s its potential. To pave a way for doing all this and to allow Android power users to unleash the real power of their new Samsung  S6, Chainfire, the famous XDA Elite Recognised Developer who is behind CF-Autoroot, SuperSU has already added support to his Autoroot script for the Galaxy S6. At the moment, CF-Autoroot supports 3 different variants, but it will be making its way to all the variants pretty soon. It’s pretty hard for some Android Enthusiasts to stay on the stock state of their device and they keep experimenting, and rooting the device is an essential part of performing experiments on your device.

If you’ve already got your device rooted or you are planning to root it after you get it, you may want to unroot it at a later stage. Unrooting your device is pretty easy, you can simply do so by flashing a stock firmware on your device. Loading a stock firmware will wipe the root access and bring back your device to the complete factory state, but it won’t reset the binary counter and knox counter of your Galaxy S6, that you’ve probably tripped while rooting your device in the very first place. While you’re going to unroot your device, do not expect your device to gain its warranty back, as this guide’s purpose is to bring your device back to the original stock state only. Let’s go through some early preparations and then unroot your Galaxy S6 [all variants].

 

Early Preparations

1. This guide is only for Samsung Galaxy S6 (All Variants)

Make sure that your device is exactly as mentioned above. To check out what device you have, go to Settings > More/General > About Device or Settings > About Device and match the model number. Be careful about the device model number, flashing a file on a device not listed here might result in bricking it up. In that case, we may not be held responsible.

2. Battery should be charged at least 60%!

Your device’s battery should not be weak. In case your device goes dead during the flashing process, your device may get soft bricked and you might be in need of flashing stock firmware and that will ultimately result in wiping up your data as well. So, make sure that you charge your device before you start the flashing process.

3. Use the OEM data cable to establish connection!

Always use the original data cable to establish connection between your Android device and your computer / laptop. Using ordinary data cables might interrupt the flashing process, so to avoid any mishap, you need to meet this requirement as well.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. Also, clean install is always recommended, that means you will probably have to wipe your device to install the new firmware. So, you may backup everything as listed below.

Backup SMS Messages
Backup Call Logs
Backup Contacts
Backup Media – Copy your files manually to your PC or Laptop.
Backup EFS – If rooted, otherwise skip this step.

5. Install Samsung USB drivers

In order to be able to establish connection between your PC and your Galaxy S4, you need to have the Samsung USB drivers installed on your PC. You can find all Android USB drivers here on our site.

6. Turn off Samsung Kies and other softwares while using Odin3!

Make sure that you turn off Samsung Kies while using Odin3 flashtool. Samsung Kies will interrupt Odin3 and will result in causing errors and may not let you flash your desired firwmrae. Also, make sure that you turn off any antivirus software you’ve installed and also disable firewall to avoid any connection and flashing issues.
