Dealing with the error can be a major roadblock when trying to flash or unbrick MediaTek (MTK) devices. This error specifically indicates that the device's Boot ROM (BROM) has been permanently locked via an electronic fuse (efuse), preventing standard low-level flashing tools from communicating with the processor . What Does This Error Mean?

Here are the proven methods ranked from most effective (but hardest) to simplest (but limited). brom disabled by efuse 0x146 best

To understand the weight of eFuse 0x146, one must first appreciate the role of the BROM. The BROM is the "root of trust" or the genesis point of a device’s operational life. It checks the integrity of the bootloader, initializes essential hardware, and often provides an emergency recovery mode (usually via UART or USB) if the primary software is corrupted. For developers, repair technicians, and unfortunately, malicious actors, the BROM is the ultimate backdoor. It allows for unbricking devices, flashing unauthorized firmware, or extracting data regardless of the state of the operating system. It is the master key to the hardware. Dealing with the error can be a major

Since the hardware-level eFuse cannot be "re-enabled," you must use methods that work around the blocked BROM port: Test Point Method (Hardware) Here are the proven methods ranked from most
