[Request] unlock CM6330_CM6630_CM6730_CM6830 [OEM] / asus P8P67-M PRO


I’ve been trying to unlock my oem motherboard so I can get asus AI tweaker. I’ve tried various tools and don’t seem to have any luck. I do have a spi usb programmer and I did try flashing it that way but my screen boots blank. I also try replacing my info like mei and other stuffy and still have no luck. Any advice would be appreciated. Thank you.
