Unrooting the Samsung Galaxy Core GT-I8260

  1. Download the firmware stock ROM from the link above for your country.
  2. Unzip the stock ROM and the Odin tool on the desktop so you can use them.
  3. Double-click and open the Odin app.
  4. Completely power off the Samsung Galaxy Core if it’s on at the moment.
  5. Reboot it to the download mode so we can connect it to the PC. Do that by holding the Power + Home + Volume Down buttons for about 5 seconds.
  6. Press the Volume Up button if you if get to a warning screen to finish getting in the download mode.
  7. Now you are ready to connect the device to the Windows PC. Find the USB cable and connect one end of the computer where you have Odin and the stock ROm waiting.
  8. Connect the other end of the USB cable to your device.
  9. Odin should now detect your device and change the color of the ID: COM port if the Samsung driver is working.
  10. Click the PDA or AP button with Odin and browse the desktop/computer for the firmware file/stock ROM. You must have unzipped the stock ROM before you’ll see the firmware file in the folder.
  11. Click the Start button in the Odin app without adjusting any of the default Settings in Odin.
  12. For those who don’t already know, that means making sure the re-partition box is empty; the Auto reboot and F Reset Time options are marked.

After some minutes the stock ROM will be flashed on your device and you’ll have a unrooted Samsung Galaxy Core smartphone.
