Brom Disabled By Efuse 0x146

Rarely, eFuse only affects USB BROM, not JTAG. But on modern MTK, both are fused.

Sometimes, if the preloader region is partially overwritten but the system remains locked, the BROM may still attempt to boot, find a mismatch, and then report 0x146 as a generic security violation. brom disabled by efuse 0x146

brom disabled by efuse 0x146 is a powerful defensive mechanism, but also a single point of failure: Rarely, eFuse only affects USB BROM, not JTAG

Researchers have found that on some chips, eFuse 0x146 is shadowed – meaning a soft fuse bit can override the hard fuse if the boot ROM has a bug. This has led to a few successful bypasses on older MediaTek platforms. Researchers have found that on some chips, eFuse
