[PS5 Slim EDM-040 ] Corrupted NOR suspicion

[simkard]

Dear All,

I know there is a tool that allows to verify NOR integrity, but it only works for FAT PS5 at that time (maybe I'm wrong, and if it is the case, please tell me).
I'm having a PS5 Slim which works fine, but acts weird :

• PSN logins fine and games can be downloaded
• Remote Play works to take control of the console
• Disc drive looks not connected even if :
  • It takes/ejects discs and seems to act normal but nothing pops on PS5 menu
  • Trying it on another PS5 works 100%
  • Waking up the console from rest mode shows a notification indicating "Can't use your disc drive. To use it, restart your PS5"
• Refuse to play/run games except Astro's Playground until it crashes systematically at the same location
• SAFE MODE (forced) with option 8 (RESET PS5 + USB-stick) fails at 29% with an strange error

Question is : how do we get a working CFI-2016 NOR/BIOS, modify it to include the necessary serial numbers / MAC addresses / etc ... ?

Thanks

What southbridge (61gg or 69gg) and WFi chip (j20h100/AW-XM601 or j20h104/AW-XM546) are on the board?

Hey ! you again ! You're definitely everywhere down here

Southbridge is a CXD90069GG
WiFi chip is a J20H104
SSD Controller is a CXD90070GG (just in case)

Is there any correlation with these and a potentially corrupted BIOS/NOR ?

 

[stetofix]

No direct correlation to the cause of the issue, but if you need a donor dump, the corret data for wifi and the data for the SB should be the right combination you need. If you transfer S/N, board S/N, MACs over, the donor dump should be ready to use.

Thank you for that !
As the filename includes "FW1100", am I safe to suppose that this BIOS is for v25.02-11.00.00 ?
By side of that, are FAT and SLIM consoles BIOS (NOR) the same ?

On my side I'm working on a Slim console with latest available FW version v25.05-11.60.00.05-00.00.00.0.1 >>> Will the provided BIOS file in your message will fit ?
At first sight, content is definitely not the same ...


By side of that, I do know at which memory location I have to find/replace some values, anyway, is there a formal list somewhere just to to be on the safe side ?

Thanks

The FW version in the filename should help to keep things in order. It is from a PS5 with FW 11.00 (v25.02-11.00.00)
Atm I have no dump from a PS5 slim with FW 11.60.

From my point of view atm there is no check to prevent that the SB is running with lower firmware (<- this is not the OS itself)

But the NOR data parts for the SB and WiFi chip must match the chips models which are on the board.

0x00004000 - 0x000810FF: SB data (slot A)
0x00082000 - 0x0009FFFF: SB data (slot B)
0x00100000 - 0x0010FFFF: WiFi data (slot A)
0x00110000 - 0x0011FFFF: WiFi data (slot B)

0x001C5000 - 001C58FF: UART error codes (first error code string @ 0x001C5100 (little endian)

0x001C7200 (16B): Mainboard S/N (The bold infos should be transfered to a donor dump)
0x001C7210 (17B): Console S/N
0x001C7230 (16B): Model No
0x001C7250 (16B): ? S/N
0x001C73C0 (3x6B): WiFi MACs (1st written on WiFi module, 2nd and 3rd 5Ghz and BT ?)

0x001C73E0 (16B): Package No

0X001C8068 (4B) = FW Versionnr (slot A) (little endian)

Are FAT and SLIM playstation5 BIOS/NOR the same (exception goes to specific values like S/N etc ...) ?

I have a working PS5 Slim with latest version but not same WiFi IC (AW-XM546).
Something on this console's BIOS/NOR is strange as there is nothing at following memory locations :

• 0x001C7210 which should contains "Console S/N" and only contains "FF"
• 0x001C7230 which should contains "Model No" and only contains "FF"
• 0x001C7250 which should contains "S/N" and only contains "FF"
• 0x001C73C0 which should contains "WiFi MACs" and only contains "FF"

Anyway, it is 100% working fine, can connect to PSN, play BluRay games and downloaded contents.

I have made another test on the other problematic PS5 Slim (the one this thread makes reference of) and I can see that these same memory locations falls under the same facts :

• 0x001C7210 which should contains "Console S/N" and only contains "FF"
• 0x001C7230 which should contains "Model No" and only contains "FF"
• 0x001C7250 which should contains "S/N" and only contains "FF"
• 0x001C73C0 which should contains "WiFi MACs" and only contains "FF"

Strange ... any idea ?

 

[stetofix]

That is indeed strange.
Can you post one of the dumps or send me as pm?

Just sent you a PM with a ZIP file

Hi, any update to this ? Have you figure out the problem and made it work ?

Hi, I have 2 cards with the same "problem" for me they are cards that went through the official Sony support and therefore disabled directly by Sony.

 

[JSS]

ok, so they are beyond repair and just for parts. Why would they be disabled by Sony thou ? they are functional units as far as I see ?

 

[simkard]

Yet I don't know why these consoles are mostly working but stuck with a license problem and can't even register a disc drive.

Waiting for the Y2JB to get the system jailbroken and see if I can access system files and find anything wrong inside.
At least if console can be jailbroken, it might be used as a jailbroken system and nothing more.
