I was trying to find the plate and screen numbers so I could download firmware, but when I was putting the screws back in, I realized the black wire on the battery was no longer attached to the board

There's a picture at the bottom; can anyone tell me where I'm supposed to reattach the black wire? It's somewhere at the bottom around the red wire I think...
It's a fake iPod Nano 3G, it didn't even turn on for a few days and just a couple hours ago I was able to get it to show me an hourglass. If it's not too much trouble can anyone tell me what firmware I need, too?
