MediaTek devices use a secure boot process where low-level flashing (in Download Mode) requires a signed Download Agent authorized by the OEM. An "auth bypass" allows users to: Flash Custom Firmware

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 device must be forced into its lowest-level boot state. This is usually achieved by holding down specific hardware keys (like Volume Up + Volume Down) while plugging in the USB cable, or by shorting a physical on the device's motherboard to ground. 2. Exploitation of the USB Stack

The consensus from developers, forum experts, and the open-source community is bleak.
