How To Unroot Samsung Galaxy M21
The below steps will guide you on how you can completely remove Magisk Root from your Samsung Galaxy M21 smartphone.
- Open Magisk App from your App drawer.
- Now tap on “Uninstall Magisk.”
- You will now be asked to choose two options. Select the second one, which is “Complete Uninstall.”
- Grant all the permissions asked.
- After that Magisk app will automatically download the uninstaller package and reboot the Samsung Galaxy M21 phone.
- Once your device boots up, it will be fully unrooted.
If you want to update to a newer firmware version, you should always pre-patch the AP file and flash it via Odin just like you did before, but this time, you should use the Home CSC and not the CSC file this would preserve the data when doing a firmware update with Odin.
If you’d like to revert to a fully Stock Non-Rooted ROM, you’ll need to simply flash everything from there, including the original AP file and the CSC. In order to make a full wipe, it is mandatory if you want to revert to a Stock ROM after having a rooted one to go through the CSC file, which will wipe the device once again.
