{| class="wikitable sortable"
|-
! Function !! 3.55 !! 3.56 !! 3.60+ !! Remarks
|-
| Using the features of a debug console || {{Yes}} || {{Yes}} || {{Yes}} || To effectively use features, need to use SDK related files, e.g. TargetManager etc
|-
| Using FSELFs || {{Yes}} || {{Yes}} || {{Yes}} || To create fselfs, you must have the decrypted binary first
|-
| Downgrading || {{Yes}} || {{Yes}} || {{Yes}} || Restricted to minver of that SKU/type (either metldr minver locked, or because of drivers - same limitations as Retail/CEX, but without hardware flasher)

COUNTERPRODUCTIVE EDIT WARRING: to people persistantly editing this away, please provide realworld data, not your basic 'it happens to all FAT' (this mention is about the _added_ risk, not the basic riskfactor that is common for all all 90nm RSX), as that does _not_ explain why consoles that are converted back work normaly //-->

| Backups (via Manager) : &lt;=3.56 keyed || {{Yes}}<br />(same as Retail, would need lv1.self : mmap114 and lv2.self : peek/poke patches + Manager with DEX detection/payload) || {{Yes}}<br />(see 3.55) || {{No}} ||

| HDCP off || {{No}} || {{No}} || {{No}} || Hardware limitations in the HDMI out chip (OTP ?) prevent from switching hdcp off even by forcing the setting <small>(see note below)</small>, HDCP would then appear off in the system settings but would actually still be on
<small>Note:<br />
Can use [[QA Flagging#Debug Menu settings not in Retail/CEX QA|QA debug]] (&lt;=3.56) or setmonitor.self (ProDG Target Manager - Monitor Settings Utility). See also [[XRegistry.sys#Common Settings|"XRegistry.sys /setting/display/0/hdcp"]] to enforce it to "off" setting.</small>
|-
| Burned Master Discs || {{No}} || {{No}} || {{No}} || Hardware limitations in the Drive Id's (OTP not set to 0xFFFFFFFFFFFFFFFF) prevent from using burned ps3 and ps2 masterdiscs (they are recognized as data discs), this is a check performed by the drive's firmware.

Note about FW 3.56: one would need to use custom generated keys for signing, as the random fail is fixed since that version, thus no private keys can be acquired with scekrit).

= Alternative method of writing back flash (jaicrab / bad idea) =

Put these, including your target NOR file, named rflash.bin on a stick:
* [https://dl.dropbox.com/u/35197530/Lv2diag.self Lv2diag.self]
* [https://dl.dropbox.com/u/35197530/advance.cfg advance.cfg]

Either use PSgrade/JIG and let the lv2diag.self be executed by lv1.self automatically, or use MultiMAN self loader. It will take a LONG time (35 minutes) until console stops blinking and shutdowns with red led.

Tested working on CECHG fat (256MB NAND). I suspect the reason for people bricking was they were flashing dumps of different lenghts and offsets (such as from memdump) and not the one provided by dumping with ?this?. -sk1080

== Prerequisites ==

* <strike>[https://www.psdevwiki.com/ps3/files/devtools/Cex2Dex/eEID_RKDumper/eEID_RKDumper.pkg eEID_RKDumper]</strike>
* [http://store.brewology.com/get/homebrew.php?id=24&fid=385 Multiman] or MMOS anything above 4.0.3 will work

== NOR guide ==

# Put above mentioned 3 packages in root of USB stick and install them on the PS3 using *Install Packages*
# With the USB stick still inserted, run Memdump v 0.01 and select the option "Dump Flash Storage"
# Run eEID_RKDumper. It should give 5-10 seconds black screen, beep and shutdown the console.
# Reboot the console, start MultiMan and use the filemanager to navigate to /dev_hdd0/tmp/eid_root_key and copy this file to the root of your USB stick.
# Now you should have the PCK1 (eid_root_key) and complete flash dump (flash_stor_35500.bin) of that console. Backup these 2 files for safe keeping/debricking. If you have multiple consoles, mark them as needed (e.g. serial from white sticker) to avoid confusion.

<!--// 7. download Cex2Dex.exe and place it on your desktop load the flash_stor_35500.bin for the top and rename eid_root_key to dump and load that for the bottom, next click on cex to dex.
8. If all went to plan then it will ask you to save your converted flash as my-DEX-flash.EID0.NORBIN
9. place that file on your usb (I suggest removing other files to avoid accidental flash) so you have my-DEX-flash.EID0.NORBIN on the usb.
10.Open multiman file manager and locate the my-DEX-flash.EID0.NORBIN on your usb and click it it will go through 3 pages of verification just press x on each page
Note: you must start Multiman in debug mode by holding the triggers as you start or restart MM and then update MM. Running the NORBIN file now brings up the prompts about overwriting your flash and not the HEX viewer
11. Reboot ps3, and you will be able to install any Dex Firmware //-->

= Trophy errors =

If you are getting trophy errors preventing you to play backups then make sure you perform the following steps:
# Go to recovery menu and restore default settings.
# Rebuild ps3 database from recovery menu.
# If you had a playstation id then add the playstation id/password in the playstation network settings. Try to connect once. It will ask you to upgrade your console. DO NOT upgrade! Keep the playstation id/password saved in the psn settings.

= Trivia =

Neither the [[SC_EEPROM#EEPROM Offset Table - Flags and Tokens|FSELF Control Flag nor the Debug Support Flag]] is changed, nevertheless, no functions of the DEX firmware are restricted, it behaves like a original one. Sony could just add checks in the upcoming DEX firmwares and patch this CEX2DEX conversion method. Also this isn't a full CEX-DEX conversion, seeing as the IDPS is changed only in EID0 and not also in EID5.

= DEX2CEX safe way / debricking =

<ol><li>Take that console DEX dump and convert it to the [[Product Code]] of that CEX console region (with targetID changer and that console eidrootkey)<br />
&nbsp; ''or'' <br />
Take that console CEX dump.</li></ol>

The next steps are same as [[Downgrading_with_Hardware_flasher#Patch the dump & reflash it to the console|Downgrading with Hardware flasher]]. See there for more in depth information.

# make sure byteorder is correct, if needed use Flowrebuilder to bytereverse
# take Rogero NOR patcher or Flowrebuilder+downgraderpatches and prepatch that CEX converted dump with downgrader. Flash it.
# use Recover or Factory Service Mode to install Rogero 3.55 V7 PUP (the basic downgrader that is always used to downgrade consoles)
# on install success, activate QA and do buttoncombo to check QA-debug menu comes up. then goto Recovery and install OFW 3.55 CEX /twice/ in a row, to make sure both banks are dehashed

== Debrick DEX back to DEX ==

Flash must already contain valid DEX [[Product Code]] in EID!

Use NOR patches only on NOR consoles, not on NAND!
