All of my data is gone and I Did do the restoring stuff
If all your game data is gone then it Sound like you chose the option not NOT TO SELECT: "RESTORE PS3 SYSTEM"
Now this is important, "DO NOT CLICK ON 'RESTORE PS3". That will wipe the hard drive clean. You don't want that.
A) "Rebuild PS3 Database" (this might take a little time be patient).
B) "Restore PS3 File System" (your bootup code, restoring is almost instant).
These two options will not delete any content on your HDD, but it will nuke all your sent and received messages as well as music playlists you have, and if you edited track information on any mp3s, say you renamed them all to something less ambiguous than "track 01", the names and other altered data will revert. (seriously, get a keyboard) For any messages you want to save, I would suggest sending them to another account you have, then send them back later.
I'm stuck on the preparing screen can anyone help?
Well I'll try. My best advice is just to keep waiting. It can take a long time depending on how much data you have on the drive.
