Arduino Pro Micro bricked? I have a Pro Micro board at which tried to upload a sketch with sparkfun's Pro Micro 3.3v processor selected. 

After the upload completed successfully the board did not run again and is not even detected from the arduino ide anymore. 

When I uploaded sketches with the leonardo 5.5v board selected everything went well and I had no problem. Now I can not burn the bootloader because of the arduino ide not detecting the board. 

What can i do?
Problem solved! By taping twice the reset and holding it the second time I managed to program my board and now the arduino ide detectes it and it works as expected. 

Taping and releasing the button twice did not work but holding it the second time worked for me. I am a almost complete noob in electronics for now so to me is black magic that not releasing the button did the job instead of what everyone else is suggesting.

I hope this helps a newbie sometime in the future that is frustrated with his/er bricked board
