To successfully unlock the Bootloader of the Tecno Camon C9 or C9 Pro:
  1. Backup your important stuff as unlocking the Bootloader wipes your data
  2. Enable USB Debugging on the Tecno C9 (see https://www.hovatek.com/forum/thread-10109.html)
  3. Enable OEM Unlocking under Settings > Developer options
  4. Setup ADB and Fastboot on the PC (see https://www.hovatek.com/forum/thread-588.html)
  5. Connect the phone to the PC via USB cord (while On)
  6. Launch ADB
  7. In ADB, run the following command (press Enter after the command)

    Code:

    adb devices

  8. ADB should detect the device. If ADB detects other devices but not the Tecno C9 or C9 Pro  then it must be an ADB clash, see https://www.hovatek.com/forum/thread-10111.html
  9. Once the device gets detected, boot it into Fastboot by running the following command (press Enter after the command)

    Code:

    adb reboot-bootloader

  10. The phone should now enter Fastboot (black screen with only fastboot written at the top or bottom)
  11. In Fastboot, run the following command (press Enter after the command)

    Code:

    fastboot oem unlock

  12. You should get a prompt on the device asking you to confirm Bootloader unlock, press the volume up button for Yes
  13. You should now get a success message
  14. Reboot the device by running the command below (press Enter after the command)

    Code:

    fastboot reboot
