Before diving into the error, it is essential to understand the . The BROM is the very first code that executes on a MediaTek or similar system-on-chip (SoC) when the device powers on. It is a small, read-only memory embedded inside the processor itself. The BROM cannot be modified or erased by the user or standard firmware updates. It is the "root of trust" for the boot process.
If you encounter 0x146, accept that the device is fully hardware-locked. Your options are: brom disabled by efuse 0x146

On some models, physically shorting the CLK (Clock) or VCORE pin to Ground (GND) on the motherboard can sometimes bypass the software-level block, though this is increasingly rare on the newest security patches. The BROM cannot be modified or erased by
Since BROM is dead, you must now rely on Preloader Mode for any modifications. This usually requires a highly specific, authorized Download Agent (DA) or a "patched" preloader file that matches your exact firmware version. Potential Workarounds
