Most modern tools require a specific device "Auth" file or a "Download Agent" to bypass the hardware restriction.
Dealing with BROM and eFuse requires caution. Incorrectly modifying these can lead to a device that is unusable or difficult to repair. Here are some recommendations: brom disabled by efuse 0x146
To understand why this error occurs, it is helpful to break down the underlying hardware mechanisms: Most modern tools require a specific device "Auth"
A medical IoT device intentionally used 0x146 to permanently lock the BROM after first boot. This was a security feature: if an attacker tried to dump firmware via UART, they would only see the disable message. Field failures required a full board swap. Here are some recommendations: To understand why this
