  3. You will see a screen with a warning sign after the Samsung logo, press Volume Up to proceed to Download Mode.
  4. Now connect your Galaxy 8 to your PC via USB, and Odin should display “Successful!”.
  5. Now add the firmware files according to the tabs in Odin. BL > BL, AP > AP, CP > CP, CSC > CSC, but do not add HOME_CSC to the CSC tab. Only the regular CSC file.
  6. Make sure that “Auto Reboot” and “F. Reset Time” are the only checkboxes selected under the Options tab in Odin.
  7. Click the Start button in Odin, and it will begin the flashing process. This will take a few minutes.
  8. When the firmware has been successfully flashed, Odin will display “Pass!”
  9. Now you can disconnect your device, and leave it alone until the Android setup screen is ready.
  10. In order to regain carrier specific features, you will need to successfully set up your unlocked firmware on your network.

  12. Then you can use Prince Comsy’s Odin to flash the “USERDATA” file in the UMS box of PC Odin.
