you can visit Raspberry Pi RP2040 Getting Started Guide > About Raspberry Pi Pico tab, scroll down to Resetting Flash memory section to download the flash_nuke.uf2. And flash it on your Pico.

RPi Pico BOOTSEL button broken! How to enter BOOTLOADER mode using Python code; without BOOTSEL button and un-plug/re-plug USB.

The BOOTSEL button on my Raspberry Pi Pico broken! Here is how to reset Pico and enter BOOTLOADER mode using Python (MicroPython/CircuitPython) code; such that no need touch BOOTSEL button and un-plug/re-plug USB.

 

In case the Raspberry Pi Pico is flashed MicroPython:

import machine
machine.bootloader()

In case of CircuitPython:

import microcontroller
microcontroller.on_next_reset(microcontroller.RunMode.BOOTLOADER)
microcontroller.reset()
