Select your model, click "Disable Auth" or "BROM," and follow the prompt to hold Volume Up + Volume Down while plugging in. 3. Use the "Preloader" Port Instead
The eFuse 0x146 is typically blown under these scenarios: brom disabled by efuse 0x146 best
The "disabling" of this BROM is achieved through an eFuse. Unlike software configurations that can be flipped or reset, an eFuse (electronic fuse) is a physical alteration of the silicon. Sending a specific high current through a microscopic wire physically breaks it, changing the electrical state from a logical 0 to a logical 1 permanently. In this context, bit 0x146 is a kill switch. When this bit is "blown" (programmed), the SoC hardware logic is altered to bypass or ignore the BROM’s interactive modes. Specifically, it disables the ability to enter the download or rescue mode via standard hardware interrupts (like holding a reset button during boot).

This article provides the technical breakdown and practical solutions for the "BROM disabled by efuse 0x146" error. We will explore what BROM and eFuse are, why 0x146 specifically appears, and the most effective strategies to bypass or resolve it. Unlike software configurations that can be flipped or
