The MediaTek MT6789, commercially known as the , is a popular 4G chipset used in many mid-range smartphones. Why Authentication Exists Security: Prevents unauthorized firmware flashing.
The MT6789 utilizes , SLA (Serial Link Authentication) , and DAA (Download Agent Authentication) .

As of 2026, several tools are used to exploit the MT6789 chipset, categorized into open-source scripts and commercial tools. A. Open-Source: mtkclient
The , also known as the Helio G99 , is a modern 6nm chipset found in many mid-range smartphones released around 2022 and later. Because it uses MediaTek's V6 security protocol , traditional BROM-level exploits (like the famous Kamakiri exploit used for older MTK chips) generally do not work on it. The MediaTek MT6789, commercially known as the ,
MTKClient is the primary tool for this chipset. It uses exploits like or Carbonara to bypass the SLA requirement if a valid DA is provided. Step 1 : Open a terminal in the MTKClient folder.
Installing stock or custom ROMs when the official flashing tool requires authentication.
Several well-known tools have been attempted. For example, the popular MTKClient project on GitHub has been a standard solution for older MediaTek chips, but its maintainers have publicly stated that they are unable to support the MT6789. The primary reason is that the BootROM is patched, and the device uses the new V6 protocol. As the documentation states: "For all devices with DAA, SLA and Remote-Auth activated no public solution currently exists" . A Windows PC (Windows 10 or 11 preferred) or a Linux machine
To attempt an auth bypass on the MT6789, you typically need the following environment set up on a Windows or Linux PC: : Ensure it is added to your system PATH.
The script sends the exploit payload, corrupts the stack, disables the watchdog timer, and patches the authentication routine in the chip's internal RAM. 2. Specialized Service Software
