Hi10X keyboard not working

The keyboard on my Chuwi Hi10X was not activating when connected to the tablet using magnetic hinge with 5 pin connector. I had to open the keyboard and tighten up the screws on 5 pin connector and it helped (didnt do a proper testing but it did connect after I tightened up the screws that hold the 5 pin connecto small pcb.
Included are the photos of screws that need to be taken out to open the plastic clips that hold the outer covers.
If tightening screws will not help then check if the mini cable from 5 pin connector is not crushed on the hinge or something like that.

Thank you so much for sharing it
