Can i downgrade PS3 3.56 to 3.55 FW for CFW

Alright guys, I’m not a hacker myself, but I do (did) love that 3.55 CFW. In fact, I didn’t realize how much I did until I accidentally upgraded to 3.56 when attempting to download a game update. I’ve done plenty of searching, and it sounds like I’m out of luck in regards to downgrading the firmware from 3.56 back to OFW/CFW 3.55.

Is there any even remotely successful way to downgrade the firmware back to OFW 3.55, especially one that doesn’t involve me intentionally bricking my console?

 Firmware is stored on the NAND flash on the motherboard , no way to downgrade from 3.56 or install CFW ,  PS3 Custom Firmware would recommend that if you get a new system to ensure you also install 3.6 spoofer which can be found on the forums, this won’t allow psn play however will prevent accidental and automatic upgrades whilst ofw is 3.6.

There are a couple emulators out if i’m correct, if you want to call it that but there is a way to play ps2 backups just use the search, also back to subject is it possible to just insert a new hard drive in a ps3 that you had old firmware on for instance I have 6 backwards compatible ps3 phats, i upgraded the hdd’s to 1,00 gigs, 750 gig, and so forth.

So isn’t it possible just to take the older hdd’s and put them in a ps3 you accidentally upgraded ? If so I’ll sell off my old 60gig hard drives to everyone who wants to make an offer or..? Does the ps3 remain on firmware no matter what hard drive is in it, removed or not?
