I managed to solder all the points to the PS Vita using the link you sent me. I stripped an old Iphone 4/Ipod charger and soldered the wires directly to the points. I am still getting this message on my macbook pro: "because a usb device was drawing too much power...."
I put some hot glue to secure the wires to the vita. could that have done anything? I have not hooked up the mother board to a screen and full shell yet, all I have is the power button left daughter board with the power LED and the mother board and battery.
I'm going to take a vita apart and see if it works. until then, does anyone know what I could be doing wrong?
