Problem with battery board data cable.

I made it most of the way through a battery replacement. Unfortunately, my battery board data connector is messed up.

Note that there is no locking flap.

Compare this with the other end

And look! I can open it! ;)

And looking at the battery board from my old battery:

You can see that the flap is there.

I don't know how to proceed from here.

I think that the connector was defective before it went in. The scratches are me scrabbling around looking for the flap. It's simply not there.

Help? Can I swap this board for the old one or will that trigger some draconian drm?
