Imagine you're trying to pass a massive book (the ROM firmware) to a friend (your Xiaomi phone) through a narrow tube (the USB cable). You start sliding pages through, but suddenly, the person on the other end stops responding. You wait for a signal, but after a certain number of seconds, you give up and shout, "Timeout!"
If the error persists, the log tells you exactly where the timeout is happening. Navigate to: C:\MiFlash\Log Open the most recent log.txt . Look for these phrases: mi flash tool timeout error top
