October 16, 2012 // 2:55 am - Today the Italian PlayStation 3 developers at PS3ITA have released a PSoN DEX PKG allowing PS3 DEX (Debug) PSN access without the Software Pack nor FckPSN required for those who have converted their console from PS3 CEX to DEX.

Download: PS3ITA_PSoN_DEX.pkg / PS3ITA_PSoN_DEX_V2.pkg / Change_IDPS.pkg / Change_IDPS-All_Region.pkg

From their blog, roughly translated: Fresh news.. now thanks to itskamel you can access the store without FckPSN with a PS3 CEX.

Thanks to his work (and that of the people who helped him) we were able to develop a version for PS3 DEX.

Requirements: PS3 Debug (DEX) upright any CFW 3.55

1) Install "PSoN_DEX" on your PS3 DEX (Update: use "PS3ITA_PSoN_DEX_V2.pkg" on PS3 instead)
2) Start "PSoN_DEX" and wait for the reboot of the console
3) Install "Change_IDPS" on PS3 (Update: use "Change_IDPS-All_Region" on PS3 instead)
4) Run "Change_IDPS"
5) Connect to PSN


  • Change_IDPS must be started after every reboot of the console before groped access to the PSN (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 as European (0 x 85)

Thanks to all the people involved in the implementation of the version for PS3 CEX, without them this would never come out PSoN DEX: itskamel, anonymous person, BobbyBlunt, EUSS, Zecoxao, sandungas.

Note: The article has been updated with Change_IDPS-All_Region.pkg. This new PKG files allow you to set the IDPS according to your region (EU, USA, etc..) Through an automated recognition.

Update: Italian PS3 ccene developer Rancid has been hard at work the last few days, first releasing PSoN and Change_IDPS Applications which allow users on DEX 3.55 access online, and now he's updated both apps again to include automatically setting your region in change_IDPS application and updating PSoN to version 2 which includes access to the PS3 Store and access to the TV section of the XMB.

UK users have an added bonus by getting access to 4OD and ITV Player, (BBC Iplayer not working), all without losing your Debug menus, no messing around with dev_blind or replacing certificates.

I'm on 3.55 supposedly i have my CEX-FLASH-EIDO.NORBIN and my DEX one and i have flashCEX.bin. Whenever i go into multiman and go to copy my CEX flash it says i must be running a 3.55CEX/DEX firmware but im not sure which one i'm currently running thought i'd be running one or the other but it says i need to install a 3.55 firmware which at the moment is not possible any other suggestions and thanks for the reply

Got it working man just now thanks very much man

when dex converted, it always will show you the minimal firmware you can install on it in recovery. nothing wrong on this.

the other thing is now, you only have installed a dex cfw with cex kernel I can imagine. there is no other way to install retail firmware when target id is set to dex.

have you tried to update from pseudo recovery called with toolbox but a dex cfw? if it is 3.55 you can also use a 3.55 dex ofw though. or have you tried any dex cfw at all?

if you have your cex norflash you can also flash eid with multiman if toolbox does not work.

Hi there. About 5 days ago i was running Rebug 4.46.1 and i had made it DEX PS3. That night my PS3 suddenly froze and i had to pull the power plug out to try turn it back on.

When i turn it on it goes straight in recovery menu and says i need to update to a version higher then 2.50 as the system cannot run on this firmware.

My PS3 was running Rebug 4.46.1 REX so I didnt know why it asked me for 2.50. I tried every firmware and cfw and ofw but none worked. Then after spending about 40 hours looking for a solution i found a download that sort of takes your DEX away or something. I installed that and my PS3 restarted and looked fine. It then said i was running firmware 3.55. If i go to system update it says i need to update to a version higher than 2.45.

I installed rebug tool box and it said my LV2 kernal was CEX and my Target ID was DEX. I cant install rebug or any firmware. Every firmware i try install comes up as 3.55 and is grey and i cant select it. I installed multiman and looked at system information and it said i was running firmware 0.00 DEX Please help!! Any solution gratefuul and will be tried

Hello people,

I want to downgrade my ps3 from 4.46 to 3.55 so i can install MLT Dex firmware 4.41. The ps3 has no working bluray or logic board. There is something im worried about. Will i be able to downgrade from 4.46 to 3.55 without either bluray or logic board? i think rogero downgrade is no BT/logic board patched, but i'm wondering about the part where i need to QA Toggle the ps3. Is there a way to enable QA toggle on 4.46 or 4.50?

MLT cfw 4.46 and 4.50 has a way of launching homebrew without bluray or logic board but i dont think i can with cfw 3.55. My plan is to upgrade from 4.46 to 4.50 MLT first to pick up eid_Root_Key that is needed for dex firmware, downgrade to 3.55 then back up to dex 4.41

i really need help with this since i dont have a flasher + its PHAT 60 gb ps3 meaning if i fail then flashing it would be a lot harder/expensive. Much cheers for any replies/comments!
