Giovanni Riva, looking at the images and checking where you said you applied glue, it appears as if your connector came off the board. Yes, it looks like you have enough of the original contacts left that you can solder it. Leave it the way you have it right now and apply solder bridges with a very fine-tipped soldering iron. The glue may not support the points making contact. Hope this helps, good luck.
The connector is CN904 : Upper FPCB Conn1.
- no Power on
- no USB
- no Receiver
The schematic may be what you are looking for to determine which pin does what. It is not as easy as just positive and negative connection :-)
I would definitely suggest to purchase a fine soldering iron and get the connector resoldered. It'll be a 5 minute job for someone :-)
