(Based on a discussion in the Evilnat thread)
I have a CECHL04, sporting Evilnat 4.88.2. I love it, and love that used games actually exist for it and are incredibly cheap, so I bought a lot of discs over the course of the past year since I bought it. In general, most of my games work, some work with damaged sectors... and then there's those discs:
You could argue that this particular disc is scuffed or damaged enough to throw this error, but when you look at the data side, its pristine.
I returned this copy of Infamous and swapped it with something else that works, and all was fine, but I kept running into even more of these discs. Off the top of my head: Uncharted, Bakugan Battle Brawlers, MotorStorm, Brothers in Arms Hell's Highway, Battlefield Bad Company 2, and Fear 2.
I first thought the discs were super badly damaged and that's the end of it, but it kept bothering me and internet search results were super vague about it (like HDD issues, but my HDD works fine), so I did what I did best: overthink about it.
It's always weird that Multiman can dump these discs 100% without issues, but Managunz's IRD check would give me like 4 or 5 inconsequential files as Valid (XMB stuff) but everything else modified. When I do a decrypted dump with Managunz, it throws these messages in the first second before giving up:
The dump itself wouldn't run (and throws a different error)...I also remember that PS3 disc encryption covers all but a few files, yep, the XMB stuff from earlier. Could the dump be encrypted? I turn to the VGPC discord server next thing and talk it out with the cool people there; on their instructions I made an encrypted dump of Bakugan and MotorStorm with Managunz, and moved them over to my PC. Before decrypting Bakugan, I compared its checksums with Redump's, and they all matched. In other words, the disc the console was struggling to read is Redump quality.
Then, I decrypted them with the disc keys listed on Redump and PS3Dec, and copied them back to the console, and ran them with WebMAN. They worked.
I even did a Managunz IRD check. This speaks for itself.
I'd understand if my console is obviously struggling with games, refusing to launch half my library, etc. But it boots and plays physical games just fine, I played The Last of Us like three days ago, no issues. Just yesterday my brother played a bit of Spiderman Web of Shadows off-disc. I also dumped a whole other bunch of discs successfully today.
I've really no idea why my PS3 would fail the decryption of these discs, but at the same time I don't know of anyone else with a PS3 to test these discs. Is it possible to hack the PS3 to use a user-provided decryption key to then run the games as intended? I don't know what to make of this situation, so I could use some help.
I will consider downgrading to Rebug 4.84 REX per bguerville's suggestion to rule out software shenanigans some time soon.
