If using Windows 10 or 11, you may need to disable via the Advanced Startup menu before installing the drivers to ensure they load correctly. 5. Execute the "Fastboot Devices" Check

Modern USB 3.0 (blue) and USB 3.1/3.2 (red or teal) ports transfer data too fast for the standard Fastboot protocol, leading to connection drops and timeout errors.

To understand the frustration of the timeout error, one must first appreciate the mechanics of the flashing process. When a Xiaomi device is placed in "EDL Mode" (Emergency Download Mode), it enters a state of raw vulnerability. It is essentially waiting for a computer to feed it the necessary code to wake up. The Mi Flash Tool initiates this data transfer via the Qualcomm HS-USB QDLoader interface. The timeout error usually occurs when this stream of data is interrupted or when the computer and phone lose their synchronization. The tool waits for a response, the clock ticks down, and eventually, the process aborts, leaving the user staring at a red line of failure.

The status column displays messages like ping target failed or ACK count mismatch .

Go to the directory where you installed the Mi Flash Tool. Right-click, select New > Folder , and name it exactly log . 5. Check Bootloader Status Flashing a fastboot ROM requires an unlocked bootloader.

Do blindly try fixes. Run these checks:

Note: If your phone has a Snapdragon 680 or newer, an EDL timeout means you need an authorized Xiaomi service center account. No software fix exists.
