PlacaFromHell:
Yeah, It goes well with "normal" methods
So you're saying if you follow my instructions in the previous reply the upload is successful?
PlacaFromHell:
but I can't upload my already compiled .hex with IDE.
I realize that but knowing whether the upload is successful with the Arduino IDE is very valuable information. That tells us that your Pro Micro is not damaged. It tells us that COM4 is the correct port. It tells us that the problem is with Arduino Builder. As I said before, I have no experience with Arduino Builder so I will not be able to provide further assistance with that program but the additional information may help someone else here to provide you a solution.
