Exactly same problem... my 355kmea runs unsigned code like PSN games and packages, but none of the backups work any longer... I actually still have an old machine that has 3.41 FW with dongle that works, but my slim was a 3.42 upgraded to 3.55 and then CFW but acts just as you described and I have redone it several times and can't get it to run backups.
I backed up original disks and they still won't run whether backed up by gaia or multiman on CFW 3.55.

I just installed kmeaw and multiman with the BDEMU-355KM pkg. I started multiman and it loaded all my backups. Now this is where the problem starts, I did permission for one game and tried to load it. I got a black screen so I restarted the ps3.
When I loaded multiman again, all my backups were gone. Now I know that they're still in the hd, but is there a way for me to load it on multiman? Do I have to reinstall kmeaw by installing 3.55 ofw again?
