just like you , i learned about " eid_root_key " after i aready installed 4.21.2 rebug ... and honestly some tutorials iv read about cex/dex are more confusing than helpfull , for some are not even telling about about the root_key thing and/or need to get it while in 3.55 ... and worst they dont offer some safety mesures such as dumps hash check " jumper " suggested .

Be aware that even though i was successful this is still a risky thing to do to your console, also this tutorial is not complete such as it doesn't tell you how to back up your flash so do your research, fret about every tiny detail and when you are confident that you know all you need to know, have done all the things you need to do, then do some more research, after this if you are still willing to lose your console should this fail, then and only then proceed with the final step, good luck
Final note before you start: i am not responsible for any bricked consoles you were warned above that this could brick your console and should take that very seriously!
CEX to DEX tutorial
If your firmware version is 3.55 then start at step 2.
you can backup your flash before downgrading or after upgrading back to 4.21 personally i backed it up before i downgraded
1) if you have QA'd your console downgrade to Rebug 3.55.4 (from XMB)
if your console is not QA'd then downgrade using Rebugs 999 downgrader and then install Rebug 3.55.4 over it
(get Rebug cfw and/or 999 Downgrader download link(s) from www.Rebug.me)
Rebug 3.55.4 and Rebug 999 Downgrader are the same firmware (at the time this tutorial was written) except the downgrader was modified specially for downgrading but after using the 999 Downgrader there will be a mismatch in the PS3's system files and installing 3.55.4 should fix this mismatch
to check if you're QA'd goto the settings column and highlight Network Settings then on your controller press L1+L2+L3+R1+R2+dpad down then scroll to the bottom of the settings column if you are QA'd and did the button combo correctly then there will be an entry named Debug
2) download eEID_RKDumper
-- download link (i am hotlinking from ps3scenefiles.com, they made me register but i have logged out and this link still works)
3) place eEID_RKDumper.pkg
install it, run it (be prepared for a black screen, restart, bleeps and improper shutdown warning)
4) use a file browser (i used Multiman's MMos) to go to dev_hdd0/tmp/
and copy the file named eid_root_key
(which should be only 48 bytes
in length) to usb
5) --vv FOR NOR CONSOLES ONLY vv----
follow this tutorial c2d-easy-cex-dex-method-16mb-nor-consoles
check the new DEX firmware in a hex editor at offset 0x2F075 you should see a value of 0x82, this is your TargetID and 0x82 means DEX
----^^ FOR NOR CONSOLES ONLY ^^----
6) this step is for both NAND and NOR consoles...
go back to Rebug 4.21.2 and follow this mini tutorial
REWRITE TARGET ID IN FLASH: (finally convert to DEX)
This option requires you have a valid NOR/NAND dump named correctly on dev_usb000. --snipped out unneeded part because to have gotten this far you would have already performed this snipped part--
Rename your original CEX dump to CEX-FLASH.EID0.NORBIN (16mb) or CEX-FLASH.EID0.NANDBIN (239mb or 256mb)
Rename your converted DEX dump to DEX-FLASH.EID0.NORBIN (16mb) or DEX-FLASH.EID0.NANDBIN (239mb or 256mb)
Once you have prepared your NOR/NAND dumps place them on a USB device and connect it to dev_usb000 (port on the right, closest to BD drive).
Now that you have your valid dumps named properly and connected to dev_usb000 it is a simple as selecting the option and following the onscreen prompts. Takes less than 10secs once you have your dumps prepared.
if you spot any errors or are unsure about any steps in this tutorial then stop and do some research, ask some questions, tell me of the error, then continue if you still want to.

Wakin up to a warning kewl! Best o luck son.
I've been bouncing between firmwares lately and when I decided to go for DEX I had to downgrade from 4.21.1 rebug. Every time I have downgraded I do this:

Seeing as I'm not the only one that will be playing with DEX, does anyone else think a seperate topic for debug discussion would be a good idea (to reduce the load on this thread maybe)?
I've started experimenting with sending over a new update.img while in game and I'm getting mixed results (mostly crashes).
yes a debugging topic would be good

I think my tut would work for you, you just need an alternative to step 5
Anyone thought about trying to reverse engineer the GTA EBOOT using IDA? I've been getting into that kinda stuff myself lately. Its my new hobby for now Been working on hitman and now ac3.
I wouldn't mind looking into GTA's eboot myself. Just wondering if you had anything specific you where trying to do? I'll try and help if so.
BTW be careful going to dex Make sure your super paranoid (in this case it does help) so when you back up your flash you do it multiple times and compare them using the proper methods. ps3devwiki is down atm but heres the cache of a page that can help: Validating flash dumps - PS3 Development Wiki
yes, definitely do be super paranoid, i was and i won lol...

3 i'm guessing you have DEX'd your console? or is it something you are considering?
