Find a verified hardware testpoint diagram specifically matching your device model.
Similarly, there has been community-driven work to exploit MediaTek BROM, with projects like . However, the eFuse security directly counters these public exploits. The error "Brom disabled by Efuse[0x102]" was noted to disable these public tools on some devices.
This involves opening the device and briefly grounding the CLK (Clock) pin of the eMMC/UFS memory chip to the shield or ground while connecting the USB cable.
Ensure the device has at least a 50% charge before attempting any Preloader or META mode interactions to avoid data corruption midway through. brom disabled by efuse 0x146 best
To secure their chipsets against popular software exploits (like the infamous Kamakiri BROM bypass), manufacturers utilize an —a microscopic fuse inside the MediaTek SoC.
Since the hardware BROM is disabled, you must leverage the phone's . The Preloader is the secondary bootloader stage stored in the device's flash storage. Professional servicing platforms like UnlockTool , DFT Pro , and Pandora Box can force communication using model-specific preloader authentication files.
Use fine-tipped metal tweezers to bridge the designated test point pad to the nearest copper grounding shield. The error "Brom disabled by Efuse[0x102]" was noted

: Alternative professional suites that support "Force Brom Fail" solutions. Are you working on a specific model
This works best on pre-2023 chips (MT6765, Helio G85). Newer Dimensity chips have patched this bypass. To secure their chipsets against popular software exploits
Miracle Box (Thunder Edition)
: This is a hexadecimal value. In this context, it likely refers to a specific efuse address or value that controls the BROM.
eFuses are physical components that can be changed from 0 to 1 but never reversed. The 0x146 value specifically signals that the emergency BROM port is disabled.
