**FIX FOR MP CONNECTION ISSUES AND SPINNING RING by NFS-P-s-n-**
Go to game data utility, delete patch 1.17,
- HOLD power long as it takes to fully switch off PS3.
- Release power button.
- Once it's off, hold power button again until it turns on and auto off itself.
- Release again.
- Now this time Hold it until you hear not the first but the second beep that is quickly followed by another beep and release, this will bring you to a secret menu in low resolution.
- On secret menu; Go to rebuild system database. (THIS WILL DELETE MESSAGES AND PLAYLISTS ONLY) It will not delete any DLC, however, deleting patch 1.17 will delete DLC which can be re-installed FREE by going to PS Store / My downloads/ and re-install them free there in your download history.
Once it's rebuilded database, redownloaded patch 1.17 and then download MP pass and DLC's again from PS Store FREE as mentioned above.
This has worked for every single one of my friends and atleast literally 20+ people all who have the Disc Version of Uncharted 3.
You'll have to check your download history, not the store. Your download history lists down previous purchases by date, and redownloading is free.
