Standard "BROM Bypass" tools will not work because the entry point is dead.
The device hardware is hard-coded to reject BROM instructions unless a specific RSA signature is provided.
Dev teams behind major multi-brand flashing suites constantly update their software to handle newer eFuse configurations. Specialized tools can often bypass modern security restrictions by using custom, proprietary download agents (DA files) or leveraging newly discovered exploits within specific Preloader versions. brom disabled by efuse 0x146
These are microscopic electronic fuses inside the processor. Once they are "blown" (set to a specific value) during the manufacturing process, they cannot be unblown.

The error indicates that your MediaTek (MTK) device has a permanent hardware-level lock that prevents traditional "BROM mode" exploits.
: Some technicians attempt "test point" methods to force the device into a different state, though the 0x146 lock is designed to be resilient even against these physical interventions. Do you have the of the device you're
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.
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.
