  6. Launch Odin exe on your PC.
  7. Connect the Galaxy C9 Pro device to computer via usb cable.
    Wait for the phone to be added.

  8. In ODIN you now have to load the Nougat 7.1.1 firmware update files, the ones extracted at step 2.
    – click BL and load the C900FDDU1BQK1 file with BL in its name.
    – click CP and load the C900FDDU1BQK1 file with CP in the name.
    – click AP and load C900FDDU1BQK1 AP file.
    – click CSC and load the HOME_CSC C900FDDU1BQK1 file. (don’t load the one with only CSC in its name).

  9. Click START to begin Android 7.1.1 update installation.
    – don’t press any buttons until the update is done flashing.
  10. After the update process is completed successfully you can reboot the device in normal mode.
    The update is completed when the PASS message is shown.
  11. Unplug the phone from PC when the install is done and wait for the boot to complete.

If the FAIL message is shown by ODIN, but your phone enters in a boot loop, then you will have to repeat the whole tutorial more than once. If you repeat installation you have to make sure that your phone meets all requirements and that you won’t skip any steps.

If the PASS alert is shown by ODIN, but the Galaxy C9 Pro phone enters in a boot loop, or it gets stuck at the boot animation screen for more than 20 minutes, then you have to Factory Reset the phone.

The Factory Reset process should be applied in case you have installed the update over a custom ROM, too.

Here’s how to Factory Reset the device from Recovery Mode:

  • power off the phone.
  • boot it in Recovery Mode: press and hold Volume Up+ Home + Power buttons until the boot is complete.
  • select ‘wipe data/ factory reset’.
  • confirm.
  • reboot phone in normal mode and you’re done.
