Many modern MediaTek devices (such as MT6765, MT6762, MT6873) utilize Secure Boot Enforcement (SLA/DAA). If your device has this protection, SP Flash Tool will drop the connection during buffer allocation unless the security layer is bypassed. To fix this:
When you load a scatter file into SP Flash Tool, the software calculates a 16-bit checksum for the image files (like boot.img , system.img , or recovery.img ).
