A600 Keyboard Acting Strange...

If you remove the edge part of the cable then you should create a new connector edge by peeling of the insulator layer. I suggest to use adhesive tape.

Apply adhesive tape to the egge. Press firmly. Then remove it. Insulator layer will come of with the tape.

I tried that earlier, but the wrong side came un-done...

...in other words the side with the contacts would not peel back.

When I tried it was worked for me.
