February 11, 2014 // 7:34 pm - Following up on their previous release and RetroA 4.55 DB OFW, today PlayStation 3 developer Habib (aka smhabib) with the assistance of Team ZER0 have released ZER0 DB (Dual-Boot) OFW 4.55 for PS3 Custom Firmware (CFW) with details below.

Download: ZER0 4.55 DB OFW.PUP (194.91 MB) / ZER0 4.55 DB OFW.PUP (Mirror) / ZER0 4.55 DB OFW.PUP (Mirror #2) / ZER0 4.55 DB OFW.PUP (Mirror #3)

MD5 Hash: 39573CD7854F4BFF73CB9D8C78596DDD

HEY GUYS! As promised, here it is.


1. Matches ofw structure
2. Same size as ofw
3. Same metadata used for encrypting modules from which ecdsa checks removed (lv0's isoldr and spu_pkg_rvk_verifier)
4. Disabled 2 ecdsa checks to allow installation of cfw over (tested with my 4.55 but any should work if syscon set to 4.55)

This db ofw is EVEN MORE STEALTHED!!! So its probably the highest approach what people can get!

Finally, from igor242 (via The syscall hash check is only 1 of many sony is capable of doing. I have decided to preemptivly post just a part of relevent logs:

And a little bit more:

As for respect and love from you, I don't need either of that from you, I need you to follow our requirements in order to post your stuff here. One of those requirements being you not make unfounded claims of stealth. No such thing exists and it never did. It's that simple.

your console needs to be at a base firmware of 3.55 or less or use a hardware flasher.

you cant update this over an original firmware above 3.55

No you can't there will be no possible way unless something magically happens as of now you can only install CFW if you are in another CFW or in 3.55 OFW

I have Rogero 4.50 v1.01 running with multiman... will this CFW work with my current multiman setup?
