Make my arduino pro micro programmable again, or is a junk now ?

Hi. So I installed firmware for ps4 controller as a test but what I need is a ps3 controller. But now when I plug to my serial port I board is not recognized at all. So my question here is how to revert it the original state where board can be programmable again ? Or if it easier how to change isntalled firmware, but I'm afraid that this might not work because to make first flush I had to reset plug/unlug arduino programmable port but now is unrecognizable, when pluging/unluging uart I got avrdude: butterfly_recv(): programmer is not responding.

It should still be programmable. PS4 firmware cannot damage the arduino to the point it becomes unflashable. Make sure you're replugging both cables.

So when having uart plugged in it shows com9 in IDE but its always hanging on uploading and after unpluging it shows also
avrdude: butterfly_recv(): programmer is not respondin

I can confim that either you or avr dude has some bug, because after succesful firmware upload doing it twice it removes programmable serial port and then i can't even upload config. I've managed to flush memory by using reset pin following https://learn.sparkfun.com/tutorials/pr ... ng-and-faq.

I'm using those parts

The issue with uploading config was related with that my pins weren't inverted. But programmable port is still not accessible I don't know if thats by design, if so I think it should be written in docs how to reflash again by resetting arduino.

As far as I remember the port is available for several seconds after you connect device to the PC. Then it switches to different mode.
