Traditional "bypasses" involved shorting specific capacitors (CLK, EMMC_DATA, or CMD lines) to ground to glitch the bootrom into skipping this check. This works on older chips like MT65xx or MT67xx. However, the MT6789 implements rigorous anti-rollback and secure boot 2.0. Shorting often results in a dead device or a complete BROM panic.
An exploits vulnerabilities in the BROM to disable this requirement, allowing you to: Unbrick "dead" devices. Bypass FRP (Factory Reset Protection). mt6789 auth bypass better
On most MT6789 devices, this involves holding Volume Up + Volume Down while plugging in the USB cable. mt6789 auth bypass better
