I've been working on a Xbox controller to make it a dual controller, a normal controller, and a arcade stick.

the soldering is based in the directions found here

All of the buttons were working fine, till today, it was magically jammed...

All solder spots are ok, very clean job.

Can I cut a trace and solder somewhere else ????? I used the little spots close to the resistors at the back of the controller.

witch button is jammed o_O

the "A" button, sorry, i wasn't very clear and can be confusing.

in the diagram if u pull of that black pad there should be contacts for the axyb buttons

already tried that, lifted the pad and everything is exactly the same
I soldered everything really carefully, but suddenly, A is always active (checking with XBCD Setup utility, tried other controllers in case it was driver issue, non xbox1 where to tried.
