Why QueenUnlock builds internal repair firmware

Official Meizu distribution focuses on OTA and recovery packages. Once the device loses a valid boot path, those packages are no longer sufficient.

QueenUnlock develops internal fastboot-based repair solutions to handle real-world recovery scenarios where standard update methods fail.
