Power off the device, press and hold the Volume Up + Power button (or Volume Down on some models), and connect the USB cable to the PC to enter BROM mode.

To understand "auth bypass," one must first grasp MediaTek's multi-layered security framework. The chipset implements a defense-in-depth approach spanning the boot chain, hardware security modules, and network-based verification. MediaTek chipsets incorporate several security mechanisms that collectively protect the device from unauthorized access: Before diving into the bypass methods, it is

Historically, MediaTek BootROM exploits (such as Kamakiri or SLA/DAA bypasses) leverage vulnerabilities in the USB stack handling commands.

This is a last-resort, high-risk hardware intervention that some users have reported as a workaround, although it is not a guaranteed solution and should be approached with extreme caution. The method involves opening the phone, identifying a specific test point on the printed circuit board (PCB), and shorting it to ground. This forces the device into a special mode where the authentication is momentarily bypassed. If you share with third parties, their policies apply

These procedures immediately void manufacturer warranties.
