MI Firmware Pangu demonstrates that even modern locked bootloaders remain vulnerable to protocol-level flaws and legacy trust anchors. By chaining a BROM overflow, seccfg injection, and RPMB replay, full firmware control can be achieved without hardware modification. The name Pangu fittingly represents splitting apart the artificial heaven of "secure boot" from the earth of user freedom.

In Mi firmware, is the secure engine driving in-display fingerprint sensors. It is a black box to the Android OS, living in the TrustZone. If you are a developer, your interaction is limited to ensuring the kernel driver matches the hardware and that the binary blobs in the vendor partition are intact and correctly signed for the device's TrustZone version.

If you are diving into this because fingerprint isn't working on a custom ROM or after a firmware flash, here is the deep dive into why:

mfp status > Bootloader: UNLOCKED > Verified boot: orange state
