The error message specifies a particular efuse address: 0x146. This address corresponds to a specific security control bit in MediaTek chipsets (commonly seen on MT6765, MT6785, MT6833, MT6893, and newer Dimensity series).
When the BROM checks this efuse at boot, it finds that the bit is burned (logic 1). The configuration at 0x146 tells the BROM: "Do not allow any unauthorized or unauthenticated download agent (DA) to run. Disable DMA access. Force a secure handshake only."
Consequently, the BROM stops execution and returns the error code 0xC001000E or a plain text string: BROM disabled by efuse 0x146 (or similar, depending on the tool). brom disabled by efuse 0x146 best
The best solution is prevention. Follow these rules:
The only correct way to bypass the 0x146 restriction is to use an authenticated Download Agent (DA) signed with a key that matches the efuse configuration. Unauthorized DAs (like the generic MTK_AllInOne_DA.bin) will fail immediately. The error message specifies a particular efuse address:
Imagine this: You’ve just tried to flash a custom recovery, unbrick your Android device, or bypass the factory reset protection. You connect your phone to the PC, load up the SP Flash Tool or Miracle Box, hit "Download," and instead of a success message, you are greeted with a cryptic red text:
"BROM disabled by efuse 0x146"
Your heart sinks. The process stops. The device refuses to communicate. If you are a technician, a developer, or an enthusiastic tinkerer, this error is one of the most frustrating roadblocks you can encounter. It signals that the manufacturer has locked down the device tighter than Fort Knox.
This article provides the best 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. Success rate: 95% (if the bootloader is still intact)
