Unrooting the Samsung Galaxy S5 Mini (SM-G800H)

  1. First of all, unzip files from both Odin and Stock Firmware over to your computer by right-clicking on each of them and selecting Extract here.
  2. Launch Odin by double-clicking on its executable that you just extracted to your computer.
  3. When Odin opens, click on the PDA button and select Stock Firmware file that you extracted in the previous steps to your computer. Make sure you do not choose the archived stock firmware or it will not work.
  4. Uncheck the option that says Repartition in the Odin. It may cause issues in the procedure.

  10. Odin should now recognize your phone and show it on its main interface. Now, click the button that says Start to allow Odin to start flashing the stock firmware on your phone.
  11. Wait for the Odin to flash stock firmware on your phone. It should take some good time as you are flashing an entire operating system on your phone.
  12. When the Odin’s done flashing stock firmware, your phone should automatically reboot.
  13. You are done!

Your Samsung Galaxy S5 Mini with model number SM-G800H is now unrooted and is back to the stock firmware.

The first boot should take some time, so please have patience. Once that is done, your phone should run butterly smooth as it now does not have any apps or any modifications which can cause it to slow down.

Enjoy the pure stock version of the Android operating system on your phone!
