• Even if you keep D0 pulled up all the time it should boot into espruino after ~3 seconds so if it does not start at all then maybe you are shorting something.

    If it is too annoying I'd suggest workaround mentioned in post #2, clearing validity flag forces it into DFU after reboot. If you want to update it anyway you probably don't care about keeping current version.
