This thread might help you!

You will need -
A Jailbroken PS3 (Preferably on DEX)
A brain :dumb: :3
A flash drive (preferably more than 400mb)

FOLLOW THE TUTORIAL SLOWLY AND CAREFULLY. TAKE YOUR TIME BECAUSE IF YOU MAKE ONE MISTAKE, YOUR PS3 COULD BE BRICKED!

IF YOUR PS3 GET BRICKED IT IS NOT MY PROBLEM! DO THIS ON YOUR OWN RISK!
BUT THIS SHOULD WORK 97% OF THE TIME!

Tuto by Brenza :

Hi, i'm glad to introduce myself to the PS3 scene with this little tutorial! This works for everybody, even for those who didn't set QA Flag before converting to DEX and does not require Factory Service Mode Downgrade so the hdd will not be formatted!!

Notes:

I built a 3.55 DEX CFW with Retail CoreOS this allow you to easily dump the per_console_key_1 (aka eEID Rootkey) by using the flatz's eEID Root Key Dumper.pkg for 3.55 CEX. The CFW also has SS Patches to let you set the Glevand's qa_extra.pkg from DEX

How to create a valid CEX dump (optional, if needed)

If you lost your original CEX dump you can create a new one:

1) Install the "CFW 3.55 DEX With Retail Patched CoreOS" inside the archive
2) Install and run the homebrew eEID Root Key Dumper.pkg
3) Copy your key from /dev_hdd0/tmp/eid_root_key to c2d_WithNandSupport folder in the archive
4) Create a dump of your DEX flash (use MultiMAN, memdump, preloader.. etc)
5) Copy the dump to c2d_WithNandSupport folder in the archive
6) Use c2d to create your CEX dump (see c2d readme for help)

How to Convert from DEX to CEX

1) Install the "CFW 3.55 DEX With Retail Patched CoreOS" inside the archive
2) Install the last version of Deank's MultiMAN for CEX (min ver 4.10.00) <--- DEX version won't work
3) Install also rebook.pkg and qa_flag_extra.pkg
4) Run MultiMAN and open the filemanager (SELECT+START)
5) Rename your FLASH-CEX dump properly (if you don't have one read below how to create one)
If 16 MB dumo rename it in FLASH-CEX.EID0.NORBIN
If 239/256 MB dump rename it in FLASH-CEX.EID0.NANDBIN
6) "Open" the dump pressing "X" twice and say "yes" to all questions
7) Close MultiMAN by pressing PS, do NOT power off the PS3 until i say it
Run the homebrew reboot.pkg
9) Run the homebrew qa_flag_extra.pkg <--- If you don't hear 3 beeps try again or you'll brick
10) Power off the PS3
11) Enter in the Recovery Menu and install the original 3.55 CEX <--- Don't install it from XBM or you'll brick!

Successfully tested on my Slim without qa-flag but it should works on NAND too

Special thanks to Sguerrini97 who did half of the job. Thanks to Deank, glevand, flatz, euss and all the other guys behind ps3mfw builder! Oh, sorry my bad english!
