While holding the volume buttons (or sometimes no buttons), connect the USB cable.

If you are developing a feature to automate this bypass, focus on the following:
Open-source tools like the MTK Bypass Utility (originally developed by Kamakiri/Exploits authors) or updated Python-based scripts. mt6789 auth bypass
Unless a new, undisclosed, and highly complex hardware-level vulnerability is discovered (a "unicorn" in the security world), the MT6789 will remain locked down.
If the device won't stay in the correct mode, try connecting it without pressing any hardware buttons. ADB Force:
Understanding MT6789 Auth Bypass: Mechanics, Risks, and Security Implications While holding the volume buttons (or sometimes no
The MT6789 authentication bypass landscape represents a microcosm of modern mobile device security. While multiple CVEs—CVE-2025-20658, CVE-2025-20730, CVE-2024-20104, CVE-2026-20435, CVE-2026-20432—expose genuine vulnerabilities, the practical ability to exploit them has been significantly curtailed by MediaTek's server-side authentication evolution. For users facing bricked devices, the situation is frustrating; for attackers, the attack surface continues shrinking with each security bulletin.
: The BootROM on these newer chips is patched against standard overflow exploits.
The cat-and-mouse game between exploit developers and MediaTek's security team continues. Recent trends indicate: Install MediaTek USB VCOM drivers
is the process of exploiting a vulnerability in this authentication routine to disable security checks, allowing the device to accept custom DA loaders, read partitions, or flash custom ROMs/recovery.
For the chipset, "auth bypass" is a critical feature used to service modern smartphones from brands like Tecno, Infinix, and Xiaomi. Because this chip often has DAA (Download Agent Authentication) enabled , standard tools cannot communicate with the device without a cryptographically signed payload. Key Tools & Features for MT6789
: Ensure you are using updated MTK drivers that support both BROM and Preloader modes to avoid connection failures seen in older versions .
