By Efuse 0x146: Brom Disabled

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: Option 1: Use an Auth File (Signed DA) MediaTek provides authorized download agents (auth DA files) to OEMs. These files contain cryptographic keys that match the eFuse values. If you obtain the correct auth file for your exact device model and CPU, you can load it in SP Flash Tool and bypass the error.

If you must work on such devices, invest in supported commercial tools, collect auth files for your target models, and always treat the first boot as a point of no return. brom disabled by efuse 0x146, MediaTek BROM error, SP Flash Tool 0x146, eFuse debug disabled, bypass BROM security, auth file MediaTek. brom disabled by efuse 0x146
