a whyle ago when the fat ps3s fucked up i hadnt gon online for 3weeks and in that 3 weeks i did most the mw2 trophies, but when the ps3 thing was fixed i tryed getting my trophies back and they didnt come back as i hadnt been online to synck them to the ps3 surfa thingy.
so now when i go on the game it shows iv completed campain on the hardest mode but my trophys dont show it
is there a way i can get them back

no, don't think so

Delete game data (THAT IS NOT THE SAVE DATA) install again then resync trophies, worked for me

I've got no idea buddy, hope you get it sorted !

Have you contacted sony?

i wouldnt know what to say to sony

Did my way work mouse?

I remember they were talking about the trophies and think there gone mate i lost a few as well just one of those things mate its not like they really mean anything at the end of the day

Just bragging rights

Cant help here mate :/ Sorry, hope you get it working.
