First, make sure that **OEM unlocking** is enabled under Developer Options and that you are using the latest official Android Platform Tools. Then verify that the phone is in the actual bootloader interface—not recovery or userspace Fastboot—with:
`fastboot devices`
You can also try:
`fastboot flashing get_unlock_ability`
If that command, `fastboot flashing unlock`, and `fastboot oem unlock` all return “unknown command,” the KL4 firmware probably does not support the standard Fastboot unlocking method. I have not found an official TECNO unlocking procedure specifically for this model, so I would contact TECNO support before trying unofficial tools or files intended for another device.
Please back up everything first, because a supported bootloader unlock normally performs a complete factory reset. Avoid random “unlock” utilities, modified bootloaders, or firmware for similar models, as they could permanently brick the phone.

(21-08-2026, 06:09 PM)jd1234wh I did enabled oem unlocking . I thought as much maybe Unisoc doesn’t allow bootloader unlocking for this device
Please if found a way please let me know
The OEM unlock command (as is) won't work because it requires a token (which you can't generate because this model likely uses private keys).
Download the bootloader unlock file @ https://www.hovatek.com/archive/download...-9-kl4.218 and extract.
Power off the phone then run unlock_autopatch_9230.bat and connect the phone while holding both Volume buttons; follow the prompt.

I successfully unlocked my Tecno Pop 8 BG6 using your `unlock_autopatch_9230.bat` procedure, but I found an issue with the `spl-unlock.bin` step.
The original command in the BAT is:
`spd_dump exec_addr 0x65015f08 fdl spl-unlock.bin 0x65000800`
When I ran the BAT, this step failed with USB/Baud communication errors.
I then ran the commands manually, and the unlock succeeded when I changed that command to:
`spd_dump --wait 60 exec_addr 0x65015f08 fdl spl-unlock.bin 0x65000800`
The phone subsequently booted and reported that the **lock flag was unlocked**.
Would it be possible to update the BAT to include `--wait 60` on the `spl-unlock.bin` command? It appears the additional wait time is important for this device/BG6.
Thanks — your procedure ultimately worked perfectly once that timing issue was accounted for.
