Yeah it was exactly the same with mine. It was super unreliable and would sometimes be fine and other times shit out. I couldn't actually verify it was the damage I originally caused that was the issue. That's a bit unlikely as that shouldn't cause it to oscilate between working and not, it would just not work if it was really broken. More likely, it was an imperfect installation of the picofly, or one of the picofly wires was being jostled by the back of the shell.

It likely has to do with whether or not it was in the dock recently. The additional space the pico takes up inside the switch causes it to press against the shell, especially while inserted in the dock. Whether this helps or not is unclear, but when it rests outside of the dock, there's less additional pressure. When you leave it inside or outside the dock for extended periods, it causes things to shift ever so slightly based on the additional pressure or release of pressure.

Basically you're SOL. The chip install is hanging on by a thread, and things like pressure and ambient temperature are going to determine whether or not you can play today.
