Now I have succeeded in one Carprog unit(CARPROG FULL V9.31), with help of a sewing needle. It will go wrong because I get up two pin, and then I can not solder back the faulty pin.
Now I have managed to get another one ready for easy flash with J-Link adapter.
But I will make another one to experiment with, and rebuild to full function or better.
Below is some useful tips from forum bros. Wish this helps

… find scrap electronics board and practice on that. I use thin syringe needle and magnifying glass.. No point practicing on your working CarProgs….
Use thin solder tip or hot air off course…forgot to say… but I don’t think you would be doing it without applying heat…

needle under leg needed lifting and heat with hot air, then very carefully lift only a little just so it separates from pcb solder
Soldering iron you have to use very thin tip and just touch very end of leg to remove ( solder at very end so not actually touching leg) then you can lift with needle
And always use solder flux
Flux is the main key to easy working
