Sony PS3 Debug / Test (DEX) Firmware 4.20 Update & More Arrive

Sponsored Links
136w ago - Following up on the recent Sony PS3 Debug / Test (DEX) Firmware 4.11 update leak, today version 4.20 alongside some DEX to CEX Switcher and Downgrade PUPs for PS3 CEX to DEX conversions have arrived from an anonymous user on the PlayStation 3 Dev Wiki.

Download: PS3 Debug / Test Firmware 4.20 (178.02MB) / PS3 Debug / Test Firmware 4.20 (Mirror) / PS3 Debug / Test Firmware 4.20 (Mirror #2) / PS3 Debug / Test Firmware 4.20 (Mirror #3) / PS3 Debug / Test Firmware 4.20 (Mirror #4) / PS3 DEX to CEX Switcher PUP's (327.35MB) / PS3 4.20 DEX Downgrader (8.83MB) / Rogero PS3 3.55 DEX with Peek & Poke (162.16MB / 162.23MB) / Rogero 3.55 DEX V2 / PS3 3.55 DEX with Peek & Poke (156.76MB) / DEX to Kiosk Switcher PUP's (326.96MB) / PS3 Generator Tools 3.30 (5.67MB) / Increase the Number of Games in PS3Gen Guide / ProDG for PlayStation 3 v4.00.1.0 (59.10MB) / ProDG for PlayStation 3 v4.20.1.0 (65.89MB) / ProDG Documentation v400.1 English (19.60 MB) / PS3 Core EBOOT Dump / Rebug 3.55.2 PS3UPDAT.PUP Modded for DEX To Allow ProDG Support (178.81 MB) by Sonic-Iso / Add ReActPSN Support on DEX 3.55 Task (TCL) by haxxxen / Showtime (Older) EBOOT for DEX 4.11 and Showtime 3.4 EBOOT for DEX 4.11 and Showtime 3.5.54 EBOOT for DEX 4.11 by carldenning / PS3 DEX / Debug PS3 Updatelist

As always, keep in mind these PUP updates will currently NOT install on a retail PS3, and so they are intended for examination and comparison purposes only.

We have 100% confirmed that running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported. (8002F029)

PS3 DEX to CEX Switcher PUP's: Proudly presenting these special pups here for DEX users... got a DEX but can't get tools to use the thing? For example newer BD emu tools and such. Well don't fret. I included a set of firmwares here that will take away the pain. Once you run the first PUP it will convert your box to a "retail" box. you can then install Rebug, Kmeaw etc etc. If you ever want to go back to DEX (Debug) then just run the second PUP that came with it and viola back to Debug. Also this all only works on 3.55. kthnxbai.

PS3 4.20 DEX Downgrader: For those running DEX higher then v3.55, you might also need this special downgrade DEX pup to re-enable the feature on your converted DEX machine to go back to any lower version of firmware file. It only needs to be run once, and then you can install the normal 3.55 DEX PUP afterwards.

Description: This file enables you to downgrade again from 4.20 DEX to a lower firmware version.


1. Create a PS3 folder on a FAT32 formatted USB stick
2. In that folder create a "UPDATE" folder
3. Copy this PUP inside that "UPDATE" folder
4. Insert the USB stick in your PS3
5. Go to system and update your PS3 through "Update via Storage Media"

PS3 4.20 DEX Firmware PUP: For those wishing to upgrade to the latest in DEX firmware, here is the 4.20 PUP, but remember it still will not give you access to PSN side of the PS3 world.

Rogero 3.55 DEX with Peek & Poke: Here is Rogero's Peek & Poke DEX.

Rogero 3.55 DEX V2: Here is Rogero's DEX V2 with the features outlined HERE.

PS3 3.55 DEX with Peek and Poke: Here is the original 3.55 DEX with Peek & Poke enabled, but it's suggested using the Rogero one as it has the downgrader built-in. Another release from 3.55 DEX with Peek and Poke.

DEX to Kiosk Switcher PUP's: Proudly presenting these special pups here for DEX users... got a DEX but can't get tools to use the thing? for example newer BD emu tools and such. Well don't fret. I included a set of firmwares here that will take away the pain. once you run the first pup it will convert your box to a "kiosk" box. If you ever want to go back to DEX (Debug) then just run the second pup that came with it and viola back to Debug. Also this all only works on 3.55. kthnxbai.

PS3 Generator Tools 3.30 & ProDG for PlayStation 3 v4.00.1.0 and PlayStation 3 v4.20.1.0: I'm giving out the latest version of PS3 Gen (the Disk creation tool to be used with the DEX emulator) and PRODG (Includes debugging software and the latest version of Target Manager).

  • PS3 Gen (the Disk creation tool to be used with the DEX emulator) NOTE: Only works on DEX consoles!
  • ProDG (Includes debugging software and the latest version of Target Manager) NOTE: For usage only on DEX consoles!

From Sonic-Iso: Afaik... the reason behind the kiosk one is this. Some people can get their hands on the kiosk unit discs from retailers. These usually have nice betas. How these install is you put the disc in and restart the kiosk machine and it does this wipe and installs the betas. What i did was rip all my SHOPINSTALL folders from each disc (these are the actual betas and such) then replaced the official pup with the hacked pup and burned it to a bluray. Then i ran that puppy and got all my betaz oh and after that I run the back to DEX pup.. and rip using target manager ftw

From doggie721: Here is Ghost Recon Future Soldier (BLUS30521) update PKG Retail to Debug PKG: http://www.mediafire.com/?sml3noby1jxqoca

He has updated PKG ContentID to version 1.2 in PS3Tools as well which allows you to highlight a retail update.pkg in Windows explorer and press Ctrl+Shift+Enter to directly convert it to a DEX compatible package. You need to put psn_package_npdrm.exe in the same folder as PKG ContentID.

In related news, Itskamel has made available a NewDEXKamel.PUP (Mirror) which he states is a patched 3.55 DEX with peek and poke and also used to install retail PKGs thanking eussNL for the patch.

To quote: Ok so you converted from CEX to DEX and you have not been able to install retail pkg’s? well now you can with this firmware. 3.55 DEX ofw patched with mfw builder for peek and poke and EussNL's patch. Enjoy. Use at your own risk!

I have installed and ran Comgenie Awesome File Manager.. please post if you are running other homebrew successfully.

PSN game Mortal Kombat Arcade Collection installed and ran fine with the Duplex fix. (He owns that only one, so he tested only MK) So all PSN games should install and work. Just tested Rebug coldboot installer, and it works flawless. enjoy your coldboots. Rebug PKG installer working also! Installed Showtime 3.61 and it ran fine.

Note: You must change the filename from “NewDEXKamel.PUP” to “PS3UPDAT.PUP”

In related news from Asure: I put together the code from the different pasties, and fixed a few includes Dump_rootkey's main.cpp is a good example of how the second exploit should look.

It now compiles and runs over RPC just like the original eid0 dumper. However, by default, the actual dumping code is commented out. I uncommented it, but nothing happens, the program just sits there. This might be because of two things:

1. There are provisions for a 'isoldr.patched' in ./data/ folder, also commented. Uncommenting and using the file from PS3 Dev wiki didn't help.

2. I tried with an original 'isoldr' file from an unpacked 3.41 pup. Could be we need an unencrypted copy? Not sure at this point.

I have posted the modified source for others to peruse. This is not my work. I'm no C expert!

LSpwn: Runs like a charm on 3.41 CEX and dumps out the local storage (256kb) Could someone on DEX 4.x confirm if the lspwn PKG runs on it?

Below is a DEX to CEX video from BestHelpingsonic for those interested:

Also a PS3 4.20 DEX confirmation video from garrettcorn as follows:

Although untested (be careful if you try it!) 3ps3l0n has made available what he calls PS3 CFW 3.55 Debug 3ps3l0n (CFW355DEX.PUP) alongside a video of it in action below.

PS3 CFW 3.55 Debug 3ps3l0n Specs:

  • Allow installation/run of Pseudo-retail PKGs
  • (Of course) allows installation of Debug PKGs
  • Allows mapping of any memory area (Needed for LV2 Poke)
  • Peek/poke support
  • Allows extracting for all package types
  • Disables integrity check in System Manager
  • Allows access to all system manager services of gameos
  • Load backups, and a surprise (PSN support) for the future.

Enjoy friends

From zadow28 comes a brief guide on Playing PS3 Backups on DEX 4.20 Firmware, as follows:

Here's an guide to play backups on dex 4.20, tested rachet clank:

1. first locate game
2. in the BCES00511 folder make an folder named app_home
3. drag then the ps3_game folder and all into the app_home folder (so its app_home/PS3_GAME etc in target maneger)
4. in system software or release mode set the app_home folder and choose the one you made.
5. then grab the eboot.bin unself it.
6. then make fself
7. make_fself eboot.elf eboot.bin.
8. copy back to USR dir.
9. now in xmb there is app_home folder the game shows up there.
10. start play

Note: To fix black screen games (tested prince of persia 3d):

1. after decrypting the eboot.bin to .elf, replace /dev_bdvd to /app_home
2. then make_fself

Thanks to Dean and acab for testing.

From romantizma comes some PS3 DEX Game Fixes:

From aries2k comes some direct-boot PKG PS3 DEX 3.6+ Game Fixes: Ok, besides mmDM and targetManager theres still the old school way of playing some of the older games that have fixes. The direct boot method. although a lot of people know about this not much has been said, probably because of the very low compatibilty. There are a few gems in here and if your like me, then you might want to give your hdd some use on DEX 3.6+. I know I seen a couple of people asking about playing games from hdd0.

1. Delete any game data
2. Install the package.
3. Use FTP or file manager and copy all the files (minus the eboot) from your game USRDIR to the USRDIR on your hdd0. Copy the trophy folder if it's not already there. should be in the root folder. the same folder as the USRDIR.
4. Go to XMB and start the game.

If anyone wants to try to make their own direct boot packages:

2. Open a HexEditor and change any references from dev_bdvd to dev_hdd0 and save.
3. Rebuild the EBOOT.ELF to EBOOT.BIN using make_fself_npdrm.exe. There are tools out there that will do this if you don't have the SDK installed. just remember the Eboot(npdrm fself) can't be signed with any keys.
4. Open PARAM.SFO and change "DG" to "HG" and save. Then make a debug pkg with your modified EBOOT and PARAM.sfo

From Nicolas19 comes some more PS3 DEX Game Fixes, as follows:

From dannybest (via docs.google.com/spreadsheet/ccc?key=0Av7ERmjDknOidG9PR2h3bjRzSEdCUnNId0hnQmFleVE#gid=0):

From themanwheel (via ps3iso.com/fixes/156679-play-station-3-dex-patches.html#post696383):

From Lightyear, to quote: How to Make a DEX Update PKG (via ps3iso.com/fixes/138685-patches.html#post638572)

What to include:

1. The game's official title
2. the game's title ID (ie: BLUS69696)
3. make sure the DEX pkg originates from the newest update available so we can install all the game's patches!!

Notes: You don't need DEX EBOOTs. To run games using the built in BDEMU you need to have an official update for the game. You then unpack the update PKG and repack it as a Debug PKG... you don't need to alter the files at all. Also, on DEX you can run any game from the original disc as long as you have the required PS3 Firmware version.

PS3 DEX FIX Tutorial for Journey_Collectors_Edition_PS3-ZRY by ohnozeibricked

This works with Journey_Collectors_Edition_PS3-ZRY

A bit long winded but definitely works (tested on 4.20 DEX)

1.Go to the folder PS3_EXTRA \ D002, unpack the DATA000.PKG file with pkgview.

2.Pack the extracted folder NPUA70218 with psn_package_npdrm with this package.conf

[Register or Login to view code]

Then install pkg on PS3.

3. Make the image as you would a normal dex image (there are tutorials for this everywhere so i will not reinvent the wheel) before you click build....

4. Tick the extra contents (new format) > Setup content Root > click File-Open > select PARAM.SFO file from PS3_EXTRA folder.

5. Go to Content Information Tab, and drag and drop all files (not folders) from PS3_Extra (delete greyed out ones) then click ok.

6. Go to Volume tab click Setup Content Items, then drag and drop pkg files from each of the D00X folders one by one (as you do each one right click and edit param. Then enter the General Parameter - Title (Default) which you can get from param.sfx in each folder ie in D000

[Register or Login to view code]

So you would enter flOw in the Title (Default), drag and drop ICON2.PNG into Content Information Files Tab.. do this with each of the folders pkg's.

7. Click build and make image as usual.

You can make a seperate pkg for the other content ie flow, flower etc just do the same as in step 1 with the other folders and modify the content id. have fun

shame this wasn't a week ago when i had to go through the hassle of reverting to cex to install rebug 4.21 rex and then flip back to dex.

the zip file is passworded ? a password would be great.

Today Italian PlayStation 3 developers PS3ITA have made available what they call PS3ITA CFW 4.21 DEX which includes Change IDPS All Region 4.21 followed by version 2 containing a bug fix with details below.

Download: PS3ITA CFW 4.21 v0.9 DEX (Password: gintonic) / Change IDPS All Region 4.21 / Change_IDPS_All_Region_v2-4.21.pkg

PS3ITA_Debug_4_21_v0.9.PUP MD5: abd0aaca504a271c65a10f8122ba96c2

To quote, roughly translated: After noting the creation of "PSoN_DEX V2" and "Change_IDPS-All_Region", you PS3ITA announces the release of CFW 4.21-DEX and Change_IDPS-All_region-4_21.

Finally a good news for all users who have bought a console converted into DEX (debug / test) who want to start their own game backups regularly purchased without having to resort to various patches / fix for cfw 3.55.

The CFW has already been tested on different consoles, and we can confirm that everything works fine without any problems, including their access to the PSN and PS-STORE.

Following are the details:

Disclaimer 1

Attention! PS3ITA assumes no liability resulting from 'use of these procedures and for any damage that the console could suffer.
Use the procedure at your own risk!

Disclaimer 2

Warning! PS3ITA not instigates and does not support piracy in any way, the procedure is posted only to illustrate the operation of the cfw in a console for DEX then start the games legally purchased!


  • First 4.xx installed on PS3 CFW DEX
  • Ability to start all backups that require fw 4.31 or less
  • Access to the PSN through the use of IDPS All Change Region
  • Access to the new PS Store
  • Access to the Playstation Home

  • On some ps3 hd if you connect the external USB port on the front (dev_usb006) and start a backup, you may get a black screen, or return to see the ps3 xmb, to remedy the problem simply change usb port ..


  • Console (NOR \ NAND) with cfw / ofw fw Downgrader 3:55 DEX or DEX

IMPORTANT: If you are on ofw debug than 4.21 (type 4.25) must strictly pass before the fw Downgrader DEX

  • A USB stick formatted in FAT32.
  • CFW 4.21 PS3ITA-DEX to be installed on the console:
  • Download CFW 4.21 PS3ITA-DEX (linked above)
  • Once you have unpacked the zip (password: gintonic) make sure that the md5 fits into this: abd0aaca504a271c65a10f8122ba96c2. To check the md5 you can use this MD5Checker: getmd5checker.com/download/latest/Md5Checker.zip
  • PKG-Change_IDPS All_region-4_21 be installed on the console after cfw:
  • INSTALL CFW 4.21 PS3ITA-DEX and Change_IDPS-All_region-4_21

IMPORTANT: If you are on ofw debug than 4.21 (type 4.25) must strictly pass before the fw Downgrader DEX

  • After downloading the CFW 4.21 PS3ITA-DEX rename it to PS3UPDAT.PUP, copy it to PS3> UPDATE in your usb stick formatted in FAT32
  • Start the console from the XMB and follow the standard procedure to install your CFW 4.21 PS3ITA-DEX from usb stick formatted in FAT32 (just like you would a normal fw):
    XMB-> Settings-> System Update-> .. with USB support
  • Copy the PKG-Change_IDPS All_region-4_21 in the root of your usb stick formatted in FAT32
  • Install from XMB-> Game-> Install Package Files
  • Start-Change_IDPS All_region-4_21 and wait for the refresh of the console


  • Change_IDPS must be started after every reboot of the console before groped access to PSN and PS-STORE (if you do not get an error: 8002A224)
  • Check in the debug menu settings (it's under Network Settings), the NP Environment setting is set as np (not sp-int)
  • L 'IDPS is set in automatic mode (depending on your region (EU, USA, etc.).
  • When the Change_IDPS is functioning properly, the LED will switch on the console from the usual green color to YELLOW

A big thanks to the Team Rebug, the Three Musketeers, PS3 Dev Wiki, Graf_Chokolo, EUSS, naehrwert and especially Rancid (o) who created / the entire project.

Update: From Rancid-o: How to use the pkg: http://www.ps3ita.it/download/homebrew/Fix_Update_4.21+.pkg

1) Run a game from Multiman
2. Returning to the XMB, if you have not already done so, start the game and download the update, at this point if the update is greater than 4.21 will give the usual error 0x80010009 and return to xmb..
3. Run Fix_Update_4.21+
4. Start the game again

Note: The fix for that game is permanent. If you have already downloaded the update just run the game from multiMAN, back to the XMB, run the pkg and run the game. Sorry for the bad English, oh forgot works on all cfw 4.xx

Guys.. use version 2 of the "Change IDPS All Region": http://www.ps3ita.it/download/homebrew/Change_IDPS_All_Region_v2-4.21.pkg

The first version had a stupid "bug" that does not allow you to use the online pass purchased. Sorry for that..

Very True - I am fortunate enough to have come across a CECH2501A (Base FW 3.50), sitting in the backroom of a Radio Shack in Sacramento.. Now workin with 2 CEX and 1 DEX... DEX is hard to get used to at first but its still fun to have one for bragging rights.

Now that the PS3 is blown wide open with the release of updated CFW, the DEX is gonna start to lag behind.. (B.T.W, as you guys first reported Sony 4.30 DEX OFW, WILL BRICK your system, apparently every time, we might be stuck on 4.25 DEX unless some of these A+ Dev's find a way around Sony, again ...)
