A multi-stage exploit chain in Qualcomm's GBL (Generic Bootloader Library) on Android 16 Snapdragon 8 Elite Gen 5 devices allows bootloader unlocking by exploiting unsigned code loading in the efisp partition, combined with a fastboot command sanitization bypass to set SELinux to Permissive mode. The chain is further leveraged via Xiaomi's Hyper OS MQSAS service to bypass strict OEM bootloader unlock restrictions on Chinese-market devices.
