If you have an OPPO phone with a MediaTek processor and the bootloader is locked, this tool can help you unlock it in a simple way. I personally tested this tool in my repair shop on many OPPO MTK devices, and it works very well. It patches the preloader file so fastboot unlock becomes possible. If you do phone software work or repair flashing issues, this tool can save you a lot of time.
