Heyz!
first of all let-me present me, i'm new arround here, i'm a user from portugal. anyway, sorry if this is not the right palace to post this how to, but i felt the need of having a post or some how to, that help's us to check our dumps.

After some study and talking with the @p's at #ps3downgrade at Ef.net, i've compiled some of the info and made this tutorial to check and validade our dumps so we can avoid undisered perm bricks.

So Here it goes:

Basic stepes to verify if your bios dump is correct:

What you need:
Your ps3 Bios Backup, extracted via e3 flasher (bkps3.bin)
e3 nor dump checker v1.0 (should be used only as a complement, as it gives false positives)
Flowrebuilder v4.2.2.0
HxD - Hex Editor

Now if you follow this basic stepes, and if everything matches your ps3dump
is OK, if anything fails to macth, use another dump, as the one you're cheking
may lead you to a permanent brick

0 - open e3 nor dump checker, and check if it gives any errors.
WARNING: Don't trust only in dump checker, as it's known for it's false positives.

1 - Statistics analysis

Click here to see full text

1.1 - Open your bkps3.bin in HxD
1.2 - select analysis > statistics > select your file
1.3 - mouse over the blue bars and check if:
00's - between 18.71% - 29.01%
FF's - between 10.42% - 10.48%
rest - Below 0.5%

2 - Make Visual inspection

Click here to see full text

2.1 - Open Flowrebuilder
2.2 - select "byte reverse and EXTRACT a NOR dump File"
2.3 - select the desired bkps3.bin , and then execute operation

2.3.1 - the Dump extraction should've been done without any errors, otherwise it may lead you to a permanent brick.

2.3.2 - after extracting you should have the following output: bkps3.swap.ps3 and bkps3.swap

2.3.3 - inside the folder bkps3.swap you should have the
following items:

asecure_loader (folder)
ros0 (folder)
ros1 (folder)
bootloader_0 (.bin)
cCSD (.bin)
cISD (.bin)
cvtrm (.bin)
eEID (.bin)
trvk_pkg0 (.bin)
trvk_pkg1 (.bin)
trvk_prg0 (.bin)
trvk_prg1 (.bin)

(if you don't have them, please don't proceed! try to extract the dump again, or use an diferent dump, the one you're using will probably lead you to a permanent brick)

2.5 - open the file ...\asecure_loader\metdlr in HxD, then ctrl + a

2.5.1 - look for your s/n in the following table: http://www.ps3devwiki.com/wiki/Valid...Bbootldr_sizes , and check if your lenght field in HxD matches with Size field in the table.

2.6 - repeat the process with Bootloader_0.bin File

2.7 - now open your bkps3.swap.bin with HxD and chek if the next fields matches.

2.7.1 - header (0FACE0FF DEADBEEF), it should match with the following: http://www.ps3devwiki.com/wiki/Flash...CE0FF_DEADBEEF

2.7.2 - From offset 00000400 to 00000600 (search for offset in HxD do ctrl + g) you should have the following http://www.ps3devwiki.com/images/3/3e/HxD.png

2.7.3 - Search now for the following Hex code: 617365637572655F6C6F616465720000

2.7.3.1 -in Hxd, do ctrl+f change the datatype field for HEX, Copy and paste the code, it should be found and looks like the following: http://www.ps3devwiki.com/wiki/Flash#example_3

2.7.4 - verify the entry table trv_prg0

2.7.4.1 - search for SCE in text mode, and it should looks

like: http://www.ps3devwiki.com/wiki/Flash#example_28

2.7.5 - press f3 and several SCE data should be found, and the last one should be SCEI (check: http://www.ps3devwiki.com/wiki/Flash#example_39 (cvtrm))

2.7.6 - verify the HDD info

2.7.6.1 - searcg for your HDD brand ( ctrl+f and in text
mode type the disk brand) or else ctrl + g and it sould be in the 00f20200 offset

2.7.7 - search for your Serial - (http://www.ps3devwiki.com/wiki/Flash#example_20)

2.7.1.1 - it should be in offset 003f090 , you can also look for the 2nd part of your serial number (ex: xx-12345678-xxxxxx-cechxx)

ONCE AGAIN, CHECK EVERYTHING WITH PATIENCE, AND EVEN A THIN DETAIL MISS, DON'T PROCEED, MAKE ANOTHER DUMP!

So these are the basic stepes to check any nor e3 flasher ps3 dump.
Howerver if u still think that's something missing in your dump, you can go further with your analisys by following the info contaide in my sources:

all the credits for this tutorial goes to the @p users of irc channel #ps3downgrade at Ef.net specially to alex07 and eussNL who thoughtme and helped me with the basic how to for cheking the dumps. all i just did was to compile all the info they gave me and wrote everithing down for further use.

after writing everything donw i thought it could be useful for every1.

Hope it helps. and sorry for some bad english.
if any portuguese user, wish the tut in PT just email-me to cfcolaco @gmail.com , i'll be glad to send the TUT in PT-PT
hope it helps.

Note: I'm open tu sugestions for improoving this TUT or for any correction you think that should be made!

Thanks!

where i find Hdd information.?

in which file ?

2.7.6 - verify the HDD info 2.7.6.1 - searcg for your HDD brand ( ctrl+f and in text mode type the disk brand) or else ctrl + g and it sould be in the 00f20200 offset

Hi i have checked the guide for my fat cechj dump it does not mach but it maches the cechh :S will this stil work (Everything else went fine)?

Is your motherboard DIA-001 or DIA-002? It is possible that you have the same mobo as the CECHH, and is why it matches that one and not CECHJ.

[TheSjoeholm]

I don't know :-(
Is there a way to check that :-)
************* [ - Post Merged - ] *************
But if it matches that one so will that be fine because it is not just some strange code?

It is in big letters and numbers on your motherboard.

many ways to verify, one of them is checking metldr/bootldr filesize

so, bytereverse and extract NOR dump(for E3 dumps) using flowrebuilder, go into the extracted dump folder (bkpps3.swap.ext) and note((rightclick-properties) the filesize in bytes e.g

cech2504-datacode 1a
metldr = 59,744 bytes = E960
bootloader_0 = 193,904 bytes = 2F570


check wiki's metldr/bootloader sizes in hex on the list
use window's calculator(progammer mode) to convert from hex size to decimal like example above ^

0B 	CECH-25xx (JSD-001) with 3.56 from factory - datecode 0D
CECH-25xx (JTP-001) with 3.56 from factory - datecode 1A 	E9 60 = size metldr 	2F570 = size bootloader_0 OK

CECHJxxx should be:
EA 60 - 2EE70

and CECHHxxx should be either: (metldr/bootloader_0 size)
E7 B0 - 2F200
E8 C0 - 2EF80
or:
E8 E0 - 2EF80 identical size as ^ but with different metldr/bootloader values at the OFFSETS
E8 E0 0E 8A 2EF80 2E F4 2E F4

I know the size matches cechh but the serial number on the back of the ps3 tells me it is a cechj. What can I do to solve this if it not right?

How did you make the dump? E3 flasher?

I kinda assumed you were trying to use E3 flasher since the guide says check your E3 nor dump. If you did take your ps3 apart to install the flasher, it says the motherboard revision on the motherboard.

Has the console been refurbished? If it has been fixed before, someone could of easily put a mobo from CECHH in it. Or if Sony has refurbished it, they are known for changing the motherboard with a different revision.

My first ps3 did freez so returned it to GameStop so I don't know what then did to it
