The authentication mechanism on MTK devices often involves a handshake that verifies the integrity and authorization of any software trying to communicate with the hardware. A failure in this process, known as an "authentication bypass," can grant an entity with physical access to the device a significant level of control, potentially circumventing the operating system's security layers.
Launch your service software and navigate to the .
dev = usb.core.find(idVendor=0x0e8d, idProduct=0x2000) # MTK Preloader if dev is None: raise ValueError("Device not found")
Most "one-click" free tools that worked on older MTK chips (like the G80 or G85) will fail on the MT6789. Question: Is the security enabled mt6789 problem solved #86
Unlike the old days, you no longer need to hold volume keys for specific durations or perform complex cable tricks. The tool exploits the vulnerability instantly upon detection.
MediaTek's MT6789 chipset (marketed widely as the Helio G99 ) implements the enhanced MediaTek V6 security protocol , which permanently patches older kamakiri2 hardware vulnerabilities. mt6789 auth bypass better
: Because the bootrom is locked down, all successful MT6789 auth bypass techniques must now leverage the Preloader mode . The Preloader executes immediately after BROM and contains specific memory vulnerabilities that can still be exploited under the right conditions. Comparison of Modern MT6789 Auth Bypass Frameworks
If you are accustomed to the old "Click, Pray, Flash" method, the new workflow is refreshingly streamlined.
: Recent updates in 2024 and 2025 have shifted focus to Preloader mode . By targeting this second stage of the boot process, tools like UnlockTool and Hydra Tool have successfully bypassed security on the MT6789 for brands like Oppo, Realme, and Infinix. The Eternal Struggle
A critical authentication bypass vulnerability exists in the boot chain of the MediaTek MT6789 chipset. By interrupting the preloader's USB handshake during a specific timing window, an attacker with physical USB access can bypass and Download Agent Authentication (DAA) . This grants unauthorized access to the device's flash memory (UFS/eMMC), allowing full firmware extraction, permanent malware installation, or device bricking.
Using MTKClient GitHub Repository is the best free method to interface with an MT6789 chip. It bypasses SLA by leveraging and carbonara memory injection vulnerabilities using a valid Download Agent (DA) file. Prerequisites A Windows or Linux PC A high-quality USB-C data cable Python 3 installed with dependencies ( pyusb , json5 ) The authentication mechanism on MTK devices often involves
⚠️ : When loading a firmware scatter package inside SP Flash Tool, always manually deselect the preloader.bin partition checkbox . Writing an incompatible preloader image over secure v6 architecture can cause a hard hardware brick. 🛠️ Alternative Commercial Solutions

The most effective current methods involve using with specific loaders or specialized professional servicing tools. Top Methods for MT6789 Auth Bypass
The cleanest method uses a known vulnerability in the preloader's USB vendor request handler. This is the "better" way because it requires no hardware modification. dev = usb
Messing with the BROM of an MT6789 device carries risks. Always ensure your device battery is charged to at least 50%. If the device becomes unresponsive during the bypass, a (or holding all buttons for 15 seconds) is usually required to reset the preloader. The Bottom Line
While famous for older chips, newer versions (like v13) claim compatibility with V6 devices, though success rates vary compared to MTKClient . Why Bypass is Considered "Better" for Users Question: Is the security enabled mt6789 problem solved #86
: Install Python and the necessary drivers (LibUSB-Win32 or UsbDk).
Open your command terminal and execute the following command to install the necessary modules for low-level cryptographic handshakes: pip install pyusb pyserial json5 Use code with caution. Step-by-Step Guide: Executing a Stable MT6789 Auth Bypass
