RE your solder repair... My option would be to try and trace where that track goes from that test point... if it runs to an IC then solder there as it will be a lot stronger.
How thick is the wire you soldered on?
Glue might be ok but then if it doesn't stick it ain't going to do anything... Plus you might run the risk of IF the glue came off youd pull the track and pad up.
Obviously im just speculating here as I cant physically see the track etc etc.. just trying to cover all your options.
On a side note if you cant get anyone to repair it send it to me and il do iit in a few mins and send it back to ya... offers there if you want it
