I have a DNA75 mod that powers up fine, but unfortunately a wire has came loose that connects to the 510 pin. I accidentally pulled it loose when I took the mod apart as the battery spring mechanism was not working, which I managed to sort.
I loved the mod when it worked, it was a firm favourite, but am not handy with a soldering iron myself.
Are you still offering this service, and if so could you PM me so I know where to send it?
I would be so grateful to get it working again as I know it is an easy fix, just not one I am capable of doing.
