Brom Disabled By Efuse 0x146 ^new^ Jun 2026

When a chip returns this error, it heavily restricts standard recovery and repair workflows. Because the block occurs inside the CPU architecture before the storage drive (UFS or eMMC) even initializes, .

BROM stands for . It is a read-only memory chip embedded directly into the MediaTek processor. It contains the very first code that executes when the phone powers on. BROM mode is highly sought after by technicians because it allows low-level flashing and unlocking bypassing the operating system entirely. 2. What is an eFuse?

The security and integrity of modern mobile hardware often depend on one-way hardware switches known as electronic fuses (eFuses). Understanding the eFuse Mechanism brom disabled by efuse 0x146

Traditional MTK bypass utilities (which exploit USB stack vulnerabilities) fail instantly because the chip drops the connection before executing the vulnerability exploit.

BROM Disabled by eFuse 0x146: What It Means and How to Fix It When a chip returns this error, it heavily

The error message "BROM disabled by efuse 0x146" indicates a specific security state where the hardware-level entry point for low-level flashing has been permanently locked. The hex code

The “Brom disabled by Efuse[0x146]” error is a milestone in the ongoing tug‑of‑war between device manufacturers and the repair community. It represents the effective closure of one of the last low‑level hardware backdoors on MediaTek platforms. It is a read-only memory chip embedded directly

For many, this cryptic line means the end of the road—at least for a simple fix. This article explains exactly what “eFuse 0x146” is, why manufacturers are deploying it, which devices are affected, and whether there is any practical workaround today.
