For decrypt them we need to use spkg keyset (for 3.56+ firmwares)


To decrypt it you need to use spkg keyset.
=== History ===
The very first(early) 4.xx cfw were only installable over 3.55 because they were not having new spkg.


== History ==
spkg is suppose to be created newly.


The very first (early) 4.xx CFWs were only installable over 3.55 because they were not having new spkg.
the most easiest way for now is that you get metadata of your new pkg and decryp, then encrypt with spkg keys.


spkg is supposed to be created newly.
the reason for cfw not installable over any ofw is that we dont have spkg private keys.


The easiest way for now is that you get Certification of your new spkg and decrypt it, then encrypt with spkg keys.
ps3 verifies it on both, xmb and recovery mode.even if xmb makes it good, it will fail when installation screens pops up.


The reason why CFW is not installable over any OFW is that we dont have spkg private keys.
more info on what and how to decrypt metainfo, refer here: http://www.psdevwiki.com/ps3/SELF_File_Format_and_Decryption
