  • There is a section called ID:COM (on the left upper side of the window). The blank space underneath it will turn blue if your device is recognized. (If the phone is not recognized make sure you have installed the USB Drivers).
  • Click on ‘AP’ and add the .tar.md5 file from the firmware archive.
  • IMPORTANT! Do not place anything under the PIT section and make sure that “re-partition” is not checked. (On the left side you will see Re-partition under the Option tab).
  • When the firmware file is loaded you can press START to being the installation.
  • Don’t touch the USB cable while the firmware is being flashed.
  • At the end you will see a message saying ‘PASS” on a green background. This means that the installation is done. The device should reboot and run on the stock ROM.

Be very careful while you go through this process. Make sure you understand all the risks and that you know all the steps before installing a Samsung firmware using Odin.

Note: That after the last reboot your phone might get stuck in a boot loop. For resolving this issue you will have to access recovery mode on your Galaxy S7. From recovery you also have to make a hard reset (select “wipe data factory reset”) and clear cache (pick “wipe cache partition”). Similar, if Odin gets stuck, close it, force restart your phone, reinstall USB drivers on your computer and repeat the unroot process from above.
