thank you

Take microscope and some wires and solder. It is really simple job, you can see where should be soldered. There is only one possibility fit connector to board.

thanko you Arvika and Mr. Zabkar for quick replay
I'm asking, because there is no coper on data + and data - to solder and also one trace nerar data + 242 is in the air

where to solder data+ and data-

thank you

Follow what remains from the traces in Data+ and Data-, see where they go, and solder in that place.
It seems they go to the other side of the 242 resistors, but you need to inspect it with a good microscope.

Just lift that capacitor to see where the traces go and solder to it. Yeah, a microscope of even high powered magnifier will be helpful.

Larry means lift the crystal oscillator. I wouldnt, though, as the metal wires that go inside pull out easy. the blue marks are where the circuit traces are. You should magnify around 5x or 10x better and scrape off the green PCB coating with a hobby knife. you then solder 4 thin wires between the USB header and the circuit board. Do not solder to the middle resistors unless you confirm under magnification that the data traces go there.

It is pretty easy to do, but you must be extremely careful if you dont have much experience. If you dont magnify it, you probably will get solder where it doesnt belong and hinder recovery.
