I just replaced the keyboard with all those pesky screws. But all is working again. I missed the part in replacing the keyboard itself in the first place. You need to have the sheets in the right order and in the right orientation. Also does it need removal of the stiffening bar that run along the keyboard. I forgot when I removed it, so I was a bit puzzeld when to put it back. Would be nice to add those steps also to this otherwise perfect guide!
While reassembling make sure the small metal ring attached to the longest antenna cable goes under the left 'red' screw.
