To counter this, manufacturers (specifically on MT6765, MT6833, and newer chips) began blowing the . This forces the device to only communicate via the Preloader , which is much easier for manufacturers to secure via digital signatures. Can You Fix "BROM Disabled by efuse 0x146"?

On older devices, shorting a test point (like CLK or GND ) on the motherboard would force BROM mode. If the 0x146 fuse is blown, hardware test points no longer work.
