However, the transition enabled by eFuse 0x146 is not without significant trade-offs, primarily concerning the repairability and longevity of the device. Once the BROM is disabled, the standard mechanisms for unbricking a device are rendered inert. If a user attempts to flash a firmware update and it fails—or if the bootloader becomes corrupted due to power loss—the device becomes a permanent "paperweight." There is no recovery mode to fall back on because the mechanism to access that mode has been physically severed from the silicon. This places a high premium on the robustness of the firmware; a failure in the field becomes a total loss rather than a repairable software issue. It looks like you have encountered a specific

Permanent Lock: Unlike software locks, an efuse is a physical hardware change. Once blown, it cannot be "unblown." This disables the standard BROM entry via volume buttons or test points that most flashing tools rely on. The Challenge with Modern Security (KG/MDM) If a user attempts to flash a firmware
