So.. what’s this about “your IDPS”? yes, the backup has two sets of files, some can be decrypted right away and some can’t because they are encrypted with your IDPS (your unique ps3 device id) which is why they can’t be restored on a different ps3. If you have a CFW, you can easily get your IDPS (I’ve written a small tool to do that, released on
github, but apparently MM and Webman will also give you that information) and that will give you total control over your backup data as you would be able to decrypt and reencrypt it. If you have OFW and can’t get your IDPS, then you will not be able to dump/decode all the files from your backup, but you will still be able to create a backup that can be restored on your PS3 with no limitations (this means for example that you can restore a backup from a CFW into an OFW without any issues). I was told however that someone can get IDPS from OFW consoles and in light of this release, they might release their method soon, I can’t say more than that though, but be patient and good things come to those who wait
