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:

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 :

Code:
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:

Code:
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!
