TUTORIAL: (Step by Step Guide)

Step 4: Open Odin on your computer and connect your device while in download / Odin mode.

Odin

Step 5: Odin must recognize your phone. If your computer detects the phone correctly, one of the ID:COM boxes will turn yellow with the COM port number. You will see “Added!!” message is appearing in the Log box. This might take some minutes.

Step 6: Load the Firmware into the Odin. You need to select the files that you had extracted in step 1.

  • Click on ‘AP’ and select the extracted file.

Step 7: Check the following options in Odin:

  • Auto Reboot
  • F. Reset Time

Step 8: HIT the Start button in Odin and your installation should start now! Hold on; it will take a couple of minutes to complete.

Step 9: Once the installation is complete, your phone will reboot into recovery mode automatically and install the root package. ID:COM box will turn into green colour. Unplug your device, when you see your home screen and you are done!

NOTE: Sometimes, the phone does not get into recovery mode due to some error in the process. If this happens, do the entire series of steps again, but this time, make sure NOT to check “Auto Reboot” option in the Odin.

Pull out the device battery to turn off the phone forcefully. After that, boot your phone with Power + Volume Up + Bixby buttons and to the recovery mode manually. This will start the package installation process. That’s it!

Hurray! Your Galaxy S8 Plus has been rooted on Android 7.0 Nougat Official Firmware. Check the SuperSU App in your App list to verify.
