Report Date: 2024-05-24 Subject: mtkclient (Open-source MediaTek USB flashing & exploitation tool) Author: Security Research Team 1. Executive Summary mtkclient is a Python-based utility designed to interact with MediaTek's proprietary bootROM and preloader protocols over USB. It exploits a critical vulnerability (dubbed "DA Injection") that allows unauthorized code execution on the device's Application Processor before the operating system loads. The tool effectively bypasses factory protections, enabling full read/write access to flash memory (including NAND and eMMC), resetting of security locks, and recovery of bricked devices.

| Operation | Command | | :--- | :--- | | Read partition table | mtk rpt | | Dump bootloader | mtk r boot1 boot1.img | | Write recovery | mtk w recovery custom_recovery.img | | Unlock bootloader | mtk da seccfg unlock | | Full flash backup | mtk rf flash_dump.bin | | Enter BROM mode | mtk reset (then connect USB with volume down) | mtkclient

mtkclient is the gold standard for understanding MediaTek’s boot security. Its source code provides an invaluable reference for BROM reverse engineering. git clone https://github
