WOW, well that looks bad. If you can find the schematics for this then you will be able to fix it no problem but first you should see if the device even works. You will have to manually give it power via the correct pins and see if it charges etc and you can buy an old board off eBay and try to track down traces. But when you look at it, you have to ask yourself if its worth the time or maybe can be a challenge you want to take on. As for me, I would try to get another working board off eBay .
