• Hi @jm,

    Looks like you were following the advice for 'advanced flashing': https://www.espruino.com/Pico#advanced-r­eflashing

    That is for very low-level flashing that overwrites everything on the device, and is used to recover if something has gone very wrong! For all normal firmware updates, all you need to do is press the button while plugging the board in - no connection to any pads or pins on the board is required.

    I bet if you follow @allObjects' advice above, the update will work great.

  • Hi Gordon,
    If I press the button on the top of the pcb during plug in, nothing happens. The blinking led not changing. It's the same, when I insert the pico without pressing a button.
    How can I insert a image in the post so that I can show you the messages. If I write a link to the image a picture is not to be seen.
