Let us parse the error message piece by piece:
"BROM disabled by efuse 0x146" indicates a permanent hardware-level lockout on MediaTek (MTK) chipsets
cannot be easily wiped or have their security locks removed using generic bypass tools. brom disabled by efuse 0x146
Confirm irreversible nature
BROM is the most fundamental level of a MediaTek device's boot process. Historically, technicians used it to unbrick phones or bypass screen locks because it could communicate with a computer before the operating system or security layers loaded. Why the 0x146 Error Occurs Let us parse the error message piece by
. This requires a device-specific, authorized "signed preloader" or a specialized service tool that supports "Auth" (Authentication) for that specific model. Potential Solutions Authorized Service Tools : Use professional tools like UnlockTool Pandora Box
On some devices, shorting specific test points on the motherboard (e.g., KCOL0 to KROW0 or CMD to CLK on eMMC) can force the SoC to bypass the eFuse check temporarily. This is advanced and requires disassembly. Even then, success is not guaranteed for error 0x146 . Why the 0x146 Error Occurs
Because eFuse is a physical, one-time programmable memory, you once the fuse is blown. However, you do not necessarily need full BROM access. The error means the BROM refuses the standard handshake. You have three possible avenues:
