[Development] How to unlock the Bootloader of a Tecno Camon C9 or Tecno Camon C9 Pro

#1
(This post was last modified: 09-20-2016, 06:19 PM by hovatek. )

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://forum.hovatek.com/thread-10109.html)
* Enable OEM Unlocking under Settings > Developer options
* Setup ADB and Fastboot on the PC (see https://forum.hovatek.com/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://forum.hovatek.com/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

You probably didnt enable OEM unlocking as instructed by the guide
