Amy way or any flux I can make it soldering.pin again or is it damage be on repair or can. A new U2 reball fix that problem I can still see the pin 3 of it is dark color will it still work any flux and copper paste or 60 40 solder with copper fix this problem

Could you give a little history of the issue and rephrase the question? I have read several times and can’t understand the question. Thank you
