@CaptainCPS-X - Appreciate you completing the testing and putting up a guide great effort!

A quick question, so now that you have completed your NAND CEX2DEX conversion, how are you now reverting back to CEX if and when you need to? Is it the same method as @GraVoX959 where by he uses Multiman to flash only the EID ??

Cheers

On NAND it should be possible from DEX FW 3.55, since that version can be put in Service Mode, therefore allowing Jaicrab Preloader Advance v3.1 to Re-Flash the CEX dump backup.

Btw, multiMAN flashes the whole NOR flash dump (16MB). The fact that the file has EID0 written on its file-name doesn't mean is just the EID0. After doing so you must install CEX OFW 3.55, then CEX CFW 3.55 as needed.

I will make a Sub-Guide on how to go back to CEX from DEX, when I get some time to do so.

SeeYa!

I've been thinking about this and wondered what would be the best way to get the cleanest dump of a nor/nand.

Myself, I think it would be better to revert to 3.55OFW and use Preloader to dump. That way, there will be no other flags present which could cause problems later.

Once you have a clean dump, flash 3.55OOS++ and use Linux to get your EID root key and once done, flash back to 3.55 OFW and then use Preloader to flash the DEX.

I know it's extra steps but the dumps would be clean.

What do you guys think?

I recommend 200% to use Factory Service Mode Tool v2 + JaiCrab Preloader Advance v3.1 to dump or re-flash both NOR / NAND PS3 models.

In my personal experience all other methods to acquire the Flash Dump for NAND skip a section from the flash therefore resulting in a incomplete ~239MB dump, instead of the proper 256MB dump.

The ONLY method for NAND to get a valid + complete flash dump (similar to Hardware method) is by using JaiCrab Preloader Advance v3.1.

PS3DevWiki has precise information about this:

http://www.ps3devwiki.com/wiki/Hardw...ND_from_GameOS

Difference between hardware dumps and software dumps ps3vflasha hardware dumps 256 MB (268,435,456 bytes) bootldr is at 0x000000 on NAND (0xFC0000 on NOR) software dumps dump size = 239 MB (251,396,096 bytes) bootldr not at 0x000000 on NAND : 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000010 00 00 00 00 0F AC E0 FF 00 00 00 00 DE AD BE EF .....¬à ÿ....ÞÂ*¾ï reason: addi %r12, %r4, 0x200 # r4 = start sector 256MB NAND consoles have a hidden section of size 0x40000 (0x200 * 512 byte sector = 0x40000) hidden by the hv. The hv hides it at address 002786E8 Original code : 0x39840200f8010090 Change to : 0x39840000f8010090

And here you have my previous post with some information on this matter:

PS: I will include detailed information about this on my guide ASAP, so people don't use bad "software dumps".

EDIT: I will go sleep now its almost 5:00 AM here, when I wake up the package should be done uploading and I will post my guide, I just have to hit "Submit New Thread" xD.

SeeYa!

Agreed, Preloader should be a given as you have stated it gives a 256mb dump.

I think if the dump is done on OFW rather than CFW, the dump should be as clean as you are going to get it.

I dumped with Preloader 1hr ago and it does give a full 256 dump vs using flash dump I did it 7times and all of the dumps have the same MD5 Check and they are 256mb.

Have you figured out why you bricked? You did everyithing according to instruction and bricked? Is it still insecure even using MM for flashing obly 1 sector?

Nah multiMAN only flashes the EID.. that's because it caused bricks flashing the whole NOR.
c2d and mM can actually do NAND.
It doesn't need the full size dump because the EID is dumped anyway and that's all mM flashes.
DO NOT TRY YET THOUGH.. some confirmations needed first then adjustments will be made to the NOR tutorial.

Having said all that.. take a dump with preloader for backup purposes.

Hey Guys :D
I just have to register now, otherwise i will go crazy about some questions ^^

My PS3 is on 3.55 DEX now, but i can't boot some Games, that require <3.55.
So that means, that my FW need P&P, but i can't build them in with MFW Builder.

Maybe someone of you can help me out

@GraVoX959 - I included some information that DeanK sent me regarding the NOR / NAND dumps done via multiMAN and how it flash the EID0.

I would still recommend people to use JaiCrab Preloader for NAND because as you said, is good for backup purposes, in case someone have to do a FULL re-flash using Hardware, they can use that 256MB one, and not the incomplete 239MB one.

SeeYa!
