(adsbygoogle = window.adsbygoogle || []).push({}); I just got word of a newly released method for converting your CEX (retail) PS3 consoles into DEX (dev/test) machines. To the best of my knowledge, the following has yet to be verified; but for those who know what to do with this information, perhaps this may come into handy for those individuals. For now, it is recommended that your average sceners leave this process alone, until someone can confirm it's validity. The following guide may result in a brick, so please use caution and read make sure to read and understand everything before proceeding.


This is an anonymous release, so there is even more reason to take caution before attempting this process. Again, wait until there is some conformation before attempting it yourselves.
Hi Scene Sorry for my bad English. I want to give you info you pls make public. I want be anonymous. I only can say I’m from Hong Kong. I have way to get a dex, it works and is complete nothing missing

Manual to get a dex (here is everything you needed) and you have a full working dex

EID0 Key Seed and EID0 Section Key Seed are hardcoded in the isoldr

EID0 Key Seed
AB CA AD 17 71 EF AB FC 2B 92 12 76 FA C2 13 0C
37 A6 BE 3F EF 82 C7 9F 3B A5 73 3F C3 5A 69 0B
08 B3 58 F9 70 FA 16 A3 D2 FF E2 29 9E 84 1E E4
D3 DB 0E 0C 9B AE B5 1B C7 DF F1 04 67 47 2F 85

EID0 Section Key Seed
2E D7 CE 8D 1D 55 45 45 85 BF 6A 32 81 CD 03 AF

If you dump they isoldr key (EID Root Key) with metldrpwn you got from 0x00 to 0x1F the EID Root Key and from 0x20 to 0x2F the EID Root IV

use AES Encrypt to Encrypt EID0 Key Seed as data with EID Root Key as Key and EID Root IV as IV

the result contains from 0x10 to 0x20 the EID0IV

and contains from 0x20 to 0x40 the EID0Key

use AES Encrypt to Encrypt the EID0 Section Key Seed as data with the EID0Key as Key and no IV

the result will be the first 0x10 bytes of the EID0 First Section Key

the second 0x10 bytes of the EID0 First Section Key are only 0x00 bytes

EID0 is located in NAND at 0x80870 and in NOR at 0x2f070

the first 0x20 bytes of EID0 are not encrypted

at the fifth byte of EID0 (NOR example 0x2f075) your target ID is located change it to 0x82 (Debug Target ID)

use AES Decrypt to decrypt the first EID0 Section (NOR example 0x2f090). The size of the first Section is 0xC0 bytes. Use the EID0 First Section Key as Key and the EID0 IV as IV

Build the CMAC (OMAC1) hash of the decrypted EID0 Section from 0x00 to 0xA8 with EID0 First Section Key as Key. The calculated hash has to be the same as the bytes in the decrypted EID0 Section from 0xA8 to 0xB8.

At 0x5 of the decrypted EID0 Section is your target id again change it to 0x82 again

0xB8-0xC0 of the decrypted EID0 Section should be just 0x00 bytes

after you changed the target ID of the decrypted EID0 Section, create the CMAC hash of the new decrypted EID0 Section and write the new hash to the decrypted EID0 Section

use AES Encrypt to encrypt the EID0 Section and write it back to the NOR (NAND).

Now install dex Firmware with the recovery menu.

HINT: Got Petitboot on emer init go to boot gameos and do emer init again to get to the recovery menu.

You can’t login to the PSN because IDPS is obviously not valid from now on.

THIS CAN BRICK YOUR CONSOLE IF NOT DONE CORRECTLY.

“Where a will, there is way”
“You start something, you have to finish it”

UPDATE:

PS3Hax's zecoxao has confirmed this method working, and has also stated the following about requirements.

btw, you can use flasher, linux or jaicrab's preloader (basically anything that flashes the dump)

jaicrab's preloader only works correctly on NOR's, you'll have problems with NAND's, or so i've tested (thanks to a friend of mine )
But again, I am going to advise users to wait until other developers look into this method before jumping into it. Chances are there may be a user friendly option available one day soon.

Copy and paste from You must login or register to view this content.

quite pointless seeing as you lose PSN access for good

edit: i take that back, with this you could run EVERY backup released regardless of what keys its signed with.
this seems risky tho

DEX machine + PSN access = Instant Platinum EVERY game

I have any Idea what to do. If this was easier I would totally do it for the trophies

i wouldnt mess with it yet lol, i bet theyll just release a firmware soon like a sort of a new cfw i mean your the expert not me right

i really hope they get this to work it would be awesome to platinum some of those games i cant finish

Nice! i hope they get it released and working soon

Definitely Probably going to see a fw or cfw because the DEX Consoles can run , install anything Hit:Homebrew and no need to sign lol this is going to be big like the 1st release of 3.55CFW But does this still require u to be on a 3.55 PS3 or below?

Any FW, but you need E3 Flasher or something because you need to dump your ps3's nand/nor.

E3 Dual boot CEX and DEX on its way fosure
