Raspberry Pi Pico W Device is busy problem ultimate solution

foreword

Raspberry Pi Pico WI ran into this problem when using :

Device is busy or does not respond. Your options:
wait until it completes current work;
use Ctrl+C to interrupt current work;
use Stop/Restart to interrupt more and enter REPL.

The core reason is that I created one main.py, but I wrote some logic while True:, which causes it to run continuously when it is powered on, even if the firmware code is reflashed, it still runs in the flash memory.

I searched a lot on Google and couldn't find it. If I didn't see this sentence in the official document

There is no way to brick the board through software.

Maybe I'll just give up on finding the way,

solution
