To successfully unlock the Bootloader of the Tecno Camon C9 or C9 Pro:

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

Code:

adb devices
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
Once the device gets detected, boot it into Fastboot by running the following command (press Enter after the command)

Code:

adb reboot-bootloader
The phone should now enter Fastboot (black screen with only fastboot written at the top or bottom)
In Fastboot, run the following command (press Enter after the command)

Code:

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

Code:

fastboot reboot
