It can be fixed but not easily and takes time.

I'm guessing some pads that hold the soldered pins for the ZIF connectors have gone missing after being ripped off.

It can be fixed but sometimes it requires jumper wiring some of the pins if the pads / traces on the board are missing to those pins.

I recommend taking it to a person that does micro soldering / board repairs for iPad.

Not an easy or cheap fix as the connector would need to be replaced using a soldering iron / hot air rework station / microscope and etc.
