On the bottom there is a square and on the psp there is a stick, so make sure the shap e of the stick matches the shape of the hole, if the whole is wierd you can buy a nub and put it on but if its the stick your best chance is sending it to sony and getting it back but it will be 3.52 Official Firmware

If it goes onto the peg but simply falls off after it does that you could use a TINY drop of super glue to hold it there.

the analog nub keeps falling off everytime i swing the psp, its not the stick, any ideas on how to fix this other then superglue? why does it fall off anyways?
