An eFuse is a microscopic fuse etched onto the silicon chip. During production or via a secure software update, the manufacturer can pass a high current through specific fuses to break ("blow") them. This permanently changes the state of a register from 0 to 1 .

: The unchangeable code embedded inside the MediaTek processor during factory manufacturing. It executes first when a phone turns on and handles initial USB communications for firmware recovery.

The "best" fix is not a single magic button—it's a combination of the right tool, the right bypass payload, and deep understanding of MediaTek’s security architecture. Do not throw the phone away. But do not waste hours with the same broken DA file. brom disabled by efuse 0x146 best

If the software-level Preloader has been heavily patched by a recent security update, the only definitive way to bypass efuse 0x146 is by using a physical .

The error is a security sentinel that signals your MediaTek device has been permanently locked against unauthorized flashing. However, "permanent" in the world of hardware hacking is rarely absolute.

Once fuse 0x146 is blown, the CPU is hard-wired to ignore commands from BROM mode. Software tools like SP Flash Tool, UnlockTool, or MTK Client will fail because the hardware itself is no longer listening. 📖 The "Informative Story" of Security Patching Phase 1: The Golden Age of Exploits

The Test Point interrupts the standard execution flow, forcing the chip to accept authorization commands before the eFuse check locks out communication entirely. This permanently changes the state of a register from 0 to 1

: Use updated versions of servicing toolkits (such as Pandora Box, UnlockTool, or Chimera Tool). Select the exact model profile and force the tool into "Preloader Mode" rather than "BROM Mode." Ensure you hold down the specific hardware key configurations (usually Volume Up + Volume Down or Volume Down + Power) while connecting the USB cable to land directly in Preloader processing. 2. Utilize Hardware Test Points (ISP / EMMC / UFS)

Download the original factory stock ROM along with the dedicated proprietary flashing tool (e.g., Mi Flash Tool for Xiaomi).
