Ok i ran into some trouble with my test... after a long time figuring where to put the naruto demo PKG file so that the ps3 can recognize it (which proved me retarded cause i should have simply put it in the root directory) i tried installing it, only to be met by error number 80029567.

After a quick google search i found out it's a common error in retail PS3 when someone tries to install a PKG and the PS3 needs to activate it...
Anyway, i started thinking it's bizzare since i got a real TEST console.
I Downloaded CJCE TEST PKG from PS3NEWS and tried it and it installed fine.

So after thinking a bit i came to the conclusion the only reason why the demo shouldn't work is that it came off the offical PS STORE (downloaded from PC cause there's no PS store in debug)...
Just to prove my concerns, i tried downloading MGS4 DB and anoter demo only to be met by the same error...

Anyway, anyone has an idea why the hell can't i install the PKG? i thought i could install ANYTHING, but it seems i can install someones lame PKG but a real and valid PKG is out of the question... any ideas? maybe reconstrucing the PKG?
