DEX 2 CEX: Easy Way - This simply works for sure, always. NO BRICK!!!
 

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
8) 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 :rock:


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! :P

i wouldnt use this with a nand ps3 . also u never tried with a nand ps3 ,so how do u know if ppl wil brick or not on nand .

i would say your more like to brick doing following this

Can i follow this tut from a rogero 4.21 Partial DEX/CEX?

I'm interested to see the success rate of this tutorial for NOR consoles before I risk a move.

don't worry, as you follow the guide it works even on NAND ;)

well... you need to instal my DEX MFW so yes, it can be used from everyone on dex

This is the only tutorial that allow you to convert not qa-flagged back to CEX without formatting the hard drive.
If you don't have a CEX dump it explains how to create one, once you obtained cex dump you don't need anything else but reading the guide, as i sed it works for every possible situation! :)

but have u tried with nand ? cos dex to cex nand is more likely to brick , if not done right
i dont need the tutorial

no more "dex to cex brick" threads? that would be good. glad for those ppl

I never QA flagged when I went to DEX.
The only time I QA flagged was after I went back to CEX to de-hash.

I was on DEX 4.21 and now on Rebug REX 4.21 and I never had to format my drive either.

i didnt even think qa_flag_extra.pkg worked on dex

@carldenning

I suppose I should reword it as "before I went" rather than "when I went".
