Mt6789 Auth — Bypass
However, for millions of MT6789 devices already in circulation, the vulnerability is permanent. From a forensics perspective, this chipset has become the "golden bullet" – enabling full physical extraction on budget and mid-range Android phones previously considered secure.
In extreme cases for devices where software bypasses are blocked by the latest security patches, some technicians use a hardware-level "CPU Drill" to physically disable the security strap, though this is high-risk and can destroy the phone. Basic Setup Requirements (for DIY)
"I tried shorting all resistors one by one with ground (phone connected to pc with mtk bypass tool). in my case i was unable to found test point so i scratched carefully last wire on pcb below chip A from right corner. i shorted this point to ground and the port was detected and mtk auth bypass was ok. then i flashed device using sp flash tool" .

If you are currently struggling with an MT6789 device, here is a step-by-step guide to approaching your problem: mt6789 auth bypass
A class of "MT6789 auth bypass" reports refers to an authentication bypass issue affecting devices using MediaTek's MT6789 (Dimensity 700 series) SoC or related firmware components. Exploitation typically lets an attacker bypass secure-boot or trusted execution environment (TEE) protections, enabling access to sensitive operations (e.g., unlocking bootloader, installing unsigned firmware, or accessing secure keys). Impact ranges from device compromise and persistent root to extraction of credentials and rollback of security controls.
By sending malformed packets or unexpected sequences of commands, researchers can trigger memory corruption or logic flaws.
MediaTek uses signed DA files to verify that the software being flashed is official. What is Auth Bypass?
Forensic specialists use it to dump the raw Userdata partition from physically damaged but functional mainboards. However, for millions of MT6789 devices already in
The MT6789 stands out as the last widely deployed MediaTek chip with a permanently exploitable BootROM bypass.
Extracting partition images for digital forensics. ⚙️ How MT6789 Auth Bypass Works
: Uses a "Bypass Auth" option for BROM mode and an "Advanced Auth" option for Preloader mode. The "CPU Drill" Method
Follow these steps carefully to trigger the BootROM state and apply the bypass. Step 1: Prepare the Software Basic Setup Requirements (for DIY) "I tried shorting
Modifying device firmware at the BootROM level carries significant risks.
: Currently the most reliable for MT6789. It supports unlocking the bootloader and reading/writing RPMB for MT6789 V6 devices. Scorpion Tool
The MT6789 auth bypass highlights the ongoing battle between hardware-level security and security research. By finding flaws in the immutable boot ROM code, researchers can bypass manufacturer restrictions to repair, analyze, and modify Helio G99 devices. However, because modern encryption keeps user data secure even when the bootloader path is compromised, the exploit remains primarily a tool for device maintenance, custom development, and hardware forensics rather than a unilateral data breach vector.
