Once the bypass is active, open your flashing tool. In the settings, ensure "Check LIB" or "Verify Authentication" is unchecked .
Once the tool reports "Protection disabled," open your choice of flashing software, such as SP Flash Tool, over the established UART connection port.
Before connecting the phone, initiate the payload listener in your terminal: python mtk xflash boot Use code with caution.
Step-by-Step Guide: Implementing the Best Free Method via MTKClient
: Once authenticated, the script opens a secure pipeline to read partitions, bypass factory reset protections, or unlock the bootloader structure. Method 2: The Automated Commercial Solution (UnlockTool) mt6789 auth bypass better
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
These utilities host server-side OEM-signed DA files and custom exploits explicitly mapped out for MediaTek v6 architecture.
To safely bypass the secure bootloader authentication on a MediaTek (Helio G99) device, you must use modern Preloader-level exploits because older Bootrom (BROM) exploits are permanently patched on this chipset.
A valid file specific to your OEM (e.g., Oppo, Realme, Infinix). Once the bypass is active, open your flashing tool
Monitor the terminal output log. The script will initialize heap exploitation routines across the Preloader connection. The handshake is successful when the console prints:
The chipset uses MediaTek’s V6 security protocol , which features a patched BootROM that effectively blocks older exploits like kamakiri . Bypassing the authentication (SLA/DAA) on these devices requires updated methods that target the preloader or use specific DA (Download Agent) loaders. Key Methods for MT6789 Auth Bypass
Installing libusb or UsbDk filter drivers to intercept the USB connection.
Open-source projects like mtkclient are frequently updated to provide a "better" and more transparent bypass mechanism, offering full control over partitions. The Risks and Ethical Considerations Before connecting the phone, initiate the payload listener
: You must use the --loader flag and point to a proper loader from the Loaders/V6 directory.
Exploits specific overflows in the second-stage Download Agent parsing logic to side-channel authentication checks. Comprehensive Tool Comparison for MT6789 Best Suited For Key Advantages MTKClient (v2.0+) Command-Line Python Framework Free / Open-Source Developers, Advanced Linux/Windows users
Insert the USB cable directly into a rear motherboard port (avoid USB hubs).
: 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
Kamakiri exploits target older MediaTek V5 architecture chipsets by sending custom payload injections directly during the BROM handshaking phase over USB.
