Post: 3.56 Service Mode Downgrade

(adsbygoogle = window.adsbygoogle || []).push({}); Before you spam that this is impossible, please read what I have to say.

All I really want is to get my PS3 on 3.41 OFW (but if I have to, I'll update to a 3.60 CFW)

---------------------VVV INFO ABOUT ME VVV---------------------
I have 2 PS3s:
1 - the old original "PHAT" PS3 that CAN play PS2 games
(Running 3.60 OFW completely updated and online)

1 - the old "PHAT" one that CAN'T play PS2 games
(Running 3.56 OFW in Factory/Service Mode)

I have a decent amount of experience.

I run Ubuntu (Linux) on VirtualBox for the PS3.
---------------------^^^INFO ABOUT ME ^^^---------------------

I've heard many people say that it is impossible to get a PS3 out of Factory/Service Mode for these reasons (which are all true):
- the lv2 (self) key has been blocked (and no longer works)
- Recovery Mode has been taken out

I've experimented with the PS3 Internal HDD. I still can't seem to crack the encryption and access its files. Supposedly Graf_Chukolo has been able to crack the encryption using certain offsets.

Is it possible that I could decrypt my Internal HDD and/or flash a lower FW version onto it? If so, how?
(You flash FW onto NAND for Phat PS3s, and flash FW onto NOR for Slim PS3s)

I briefly looked at Graf_Chukolo's list of offsets, but I still don't know how or where to use them. (Or even if they would work).

Any other thoughts on how I might be able to downgrade this PS3? Or get it out of Service Mode?

Another thought I had was if I updated to a 3.60 CFW. Would that work? or would I get the Red Screen of Death?

If you feel like you deserve credits for anything on here, just message me.

And yeah I heard about that but forgot to add it. Do you have any idea if I could flash a 3.41 or 3.55 FW onto my Internal HDD? Would that work?


Nope lol. The hdd does not contain, and does not load, and will not load the firmware.

Correct me if I am wrong, but from looking online, I've heard of people using these "Offsets" to re-activate the lv2 key. Is this true or possible? Graf_Chokolo has a whole list of offsets, but I don't know where or how to use them. I installed his linux 2.6 tree but I still don't know what to do from there.

How sure are you? I've heard rumors of a guy that has done it with the help of Graf_Chukolo. I've also heard that you can play dumb, send it into Sony, and they will get it out of Service Mode for you.

You can decrypt you hard drive now that is possible once again using homebrew.
