  • 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.

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.
