Missing solder pads where the LCD connector sits

I was cleaning the pads in order to solder the new LCD connector to the board but i overheated while cleaning with the iron and lifted them.

So what would be the best approach to fix it?

The missing pads 13 and 17 are connected to L2044 , L2042.

I think i could do some bridging.

You’ll need to run a thin jumper wire from the closest (or most direct) connection point to the hole where the pad was. Ideally, you’ll want to loop the jumper in the pad hole and then fill it with solder so that it has a good contact patch. UV-Curable solder mask will help you fix the jumper in place so it doesn’t move when you solder the replacement FPC connector.

Here’s an example (minus the solder in the loop):

Okay so i need to make a jumper with thin wire to the coil that the pad was initially connected to and i need to make a loop with the wire and fix it with solder on the place of the missing pad, so then i would just solder the other end of the jumper to one of the FPC connector's legs, right? But at the moment i don't have UV-Curable mask, i have silver conductive paint, but the place is too tiny to proportionately place it there because the paste is thick.

And the these coils have three legs, so do i need to de-solder them then place the wire there and solder the coil back again, i basically think i need to sandwich the wire between the board and the leg of the coil?

Just find the easiest way to make the connection, I can't see the board so I can't say for certain. You can try without UV-Curable mask but what usually happens is the jumper moves around in the molten solder and given it's size, it tends to either get blown away, move away on it's own or not stay connected.

I updated the thread with photo from the microscope.

And okay i will try to fix the wire first with something, i might put from the conductive silver paste and let it dry.
