    Hello! I've heard from a friend of mine that you can downgrade the PS3 through formating it? Is it true?

    Oh ok! The only way is through chips right? And those which exist are only E3 and Nor flashers right?

    Depending on your model.

    You can use Progskeet / TEENSY++ 2.0 / InFeCtuS for NAND PS3s and Teensy++ / Progskeet / E3 Flasher for NOR PS3s.

    Or you can downgrade via CFW.

    The downgrader works, I've used it. I've even used my PSP to downgrade from 3.55 to 3.15 OFW, no hardware flasher required. So don't assume information you haven't heard of is automatically false.

    I'm not sure what you're talking about, as you're being a bit vague. You cannot downgrade a PS3 with OFW higher than 3.55 without a downgrader. The 999 downgrader is for people on CFW to downgrade to 3.55. The thread starter was told he could downgrade his PS3 by formatting it. Which is false, and since he wants to downgrade I am willing to bet does not own a PS3 that is on CFW. Therefore telling him that the 999 downgrader downgrades won't help him at all. If the downgrader was able to downgrade any PS3, then I'm sure that E3 Flashers would be out of business.

    mschumacher69 is quite knowledgeable in the PS3, so call him a what was it. "newfag" is extremely poor judgement on your part.

    You shouldn't be spreading information when you don't know what you're talking about mate...

    As @Devin said, the downgrader PUP can only downgrade 4.xx CFW to 3.55 CFW, but it cannot downgrade 3.56+ OFW to 3.55.

    Regarding the PSP, that's right, you can use it to downgrade OFW 3.55 to any lower OFW if you use it as an FSM JIG, but you won't be able to use it to downgrade 3.56+ OFW to 3.55.

    The only way to downgrade 3.56+ OFW PS3s is by using a hardware flasher, this is only if the PS3 model is old enough to be downgradable. Newer models which come pre-installed with OFW higher than 3.56 cannot be downgraded at all, even with a hardware flasher.

    the factory mode trigged on the PSP helps to boot the PS3 under "emergency" situations, but you won't be able to downgrade 3.56+ as firmware keys were updated. (3.55 and below suffered the same "glitch" so you could sign a custom firmware using the same formula)

    I've always wondered, what IS IT that prevents an older firmware from being installed than what came pre-installed? I never understood that, and nobody can give me a straight-up answer.

    Drivers for the newer hardware. Pre-installed firmware usually comes with a small hardware revision, it's normally nothing a normal user would even notice, but it is there, and the software does need to be able to handle it.

    In the PSP scene (other then in-6.x), they actually had to add a motherboard check to the downgraders because people would ignore the warnings, install a lower firmware than the base that added support for their model's hardware, and then the PSP would never boot again (since all the downgrades were on post-cIPL models).

    It's the hardware, the hardware doesn't support firmware older than what came pre-installed.

    Also, with PS3s that ship with OFW higher than 3.56, they changed metldr to metldr2 so that it doesn't support firmware lower than 3.60. Firmwares lower than 3.60 would have metldr instead of metldr2 and a PS3 that ships with OFW higher than 3.56 would have metldr2, so installing a firmware with metldr on a PS3 with metldr2 wouldn't work and a firmware cannot be signed with metldr2 because Sony changed the encryption keys and no one has them.

    If Sony didn't introduce metldr2 with 3.60+ PS3s, then it would have been possible to directly flash a 4.xx CFW using a hardware flasher without having to downgrade back to 3.55 which would have been impossible given that the PS3 ships with OFW higher than 3.55. This is what is done with PS3s that come shipped with OFW 3.56, it's impossible to downgrade them to 3.55 but they can be patched and flashed directly with 4.xx CFW using a hardware flasher because they don't have metldr2.
