Editing Talk:Validating flash dumps

<!--// ==== UserTool ====
[[User:Bluemimmosa]] This application will check the '''nor dump''' for the '''correct size''' and also will check the magical header for repetations. If it finds repetation then it will calculate the difference and also '''tell you which address line is not connected or BAD'''. This program will also extract the files such as '''raw ROS0''' '''raw ROS1''', '''metldr''', '''bootldr''', '''cISD''', '''cCSD''', '''cvtrm''', '''eEID''', '''trvk_prg0''', '''trvk_prg1''', '''trvk_pkg0''', '''trvk_pkg1''', '''cell extnor area''' correctly, and will also check the metldr if the console is downgradable or not. '''CREATED: 2011 dec 25.'''

=== Check metldr+bootldr sizes - Usertool ===
[[User:Bluemimmosa]] ''Based on the metldr and bootldr table i have coded an app that checks the byte at 0xFC0003 and test it weather its 5B or FB and decides if the console is downgradable or not. i think it may help some people.. This program also scans the file if it is of correct size or not.''

== Basic steps to verify if your bios dump is correct: ==


'''What you need:'''<br />
Your ps3 Bios Backup, extracted via e3 flasher (bkps3.bin)<br />
<span style="text-decoration: line-through;">e3 nor dump checker v1.0 (should be used only as a complement, as it gives false positives)</span><br />
Flowrebuilder v4.2.2.0<br />
HxD - Hex Editor<br />
		
Now if you follow this basic steps, and if everything matches your ps3dump is OK, if anything fails to match use another dump, the one you're checking may lead you to a permanent brick<br />

<span style="text-decoration: line-through;">'''0 -''' open e3 nor dump checker, and check if it gives any errors.</span><br />
	
'''WARNING: <span style="text-decoration: line-through;">Don't trust only in dump checker, as it's known for it's false positives.</span>'''

== Statistics analysis ==

'''1.1 -''' Open your bkps3.bin in HxD<br />
'''1.2 -''' select analysis > statistics > select your file<br />
'''1.3 -''' mouse over the blue bars and check if between known good range:<br />

{{Dumpstatistics}}

== Make Visual inspection ==

=== Extracting ===	
# Open Flowrebuilder
# select "byte reverse and EXTRACT a NOR dump File"
# select the desired bkps3.bin , and then execute operation
# the Dump extraction should've been done without any errors, otherwise it may lead you to a permanent brick.
# after extracting you should have the following output: bkps3.swap.bin and bkps3.swap.ext
# inside the folder bkps3.swap.ext you should have the following items:

<div style="float:right">[[File:Bkps3.swap.ext_folder_content.jpg|100px|thumb|left|bkps3.swap.ext folder content]]</div>	
			asecure_loader (folder)<br />
			ros0 (folder)<br />
			ros1 (folder)<br />
			bootloader_0 (.bin)<br />
			cCSD (.bin)<br />
			cISD (.bin)<br />
			cvtrm (.bin)<br />
			eEID (.bin)<br />
			trvk_pkg0 (.bin)<br />
			trvk_pkg1 (.bin)<br />
			trvk_prg0 (.bin)<br />
			trvk_prg1 (.bin)<br />

'''(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)'''<br />

=== Checking seperate files/sections ===

==== Metldr ====
http://www.ps3devwiki.com/wiki/Flash:asecure_loader

open the file \asecure_loader\metdlr in HxD, then ctrl + a<br />

look for your values in the following table:<br />http://www.ps3devwiki.com/wiki/Validating_flash_dumps#Check_metldr.2Bbootldr_sizes , 
and check if your length field in HxD matches with Size field in the table.<br />

Also check the binary is complete, without FFFF or 0000 repetition (there should only be 0000 in header @ 0x0 of binary)

==== Bootldr ====
http://www.ps3devwiki.com/wiki/Flash:bootldr

<div style="float:right">[[File:Bootloader_0_start.jpg|200px|thumb|left|bootloader_0 start]]</div>

repeat the process with Bootloader_0.bin File<br />

make sure your bootloader_0(bin) file starts proper: look at offsets 2 and 12 and compare the values against [[Validating_flash_dumps#Check_metldr.2Bbootldr_sizes]]

Also check the binary is complete, without FFFF or 0000 repetition (there should only be 0000 in header @ 0x0 of binary)

==== Header ====
http://www.ps3devwiki.com/wiki/Flash:0FACE0FF_DEADBEEF

http://www.ps3devwiki.com/wiki/Flash:Flash_Format
	
open your bkps3.swap.bin with HxD and check if the both sections matches.

==== Table ====
http://www.ps3devwiki.com/wiki/Flash:Flashregion_Table

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

==== Flashregion Table ====
http://www.ps3devwiki.com/wiki/Flash:Flashregion_Table + http://www.ps3devwiki.com/wiki/Flash:asecure_loader

Search now for the following Hex code: '''617365637572655F6C6F616465720000''' for it in Hxd, do ctrl+f change the datatype field for HEX, Copy and paste the code, it should be found and looks like sample.

==== eEID ====
http://www.ps3devwiki.com/wiki/Flash:Encrypted_Individual_Data_-_eEID

==== cISD ====
http://www.ps3devwiki.com/wiki/Flash:Individual_System_Data_-_cISD

search for your Serial<br />
it should be in offset 003F090, you can also look for the 2nd part of your serial number (ex: xx-12345678-xxxxxx)

==== cCSD ====
http://www.ps3devwiki.com/wiki/Flash:Common_System_Data_-_cCSD

==== CVTRM ====
http://www.ps3devwiki.com/wiki/Flash:cvtrm (cvtrm))

==== ROS ====
http://www.ps3devwiki.com/wiki/Flash:ROS#ros0

http://www.ps3devwiki.com/wiki/Flash:ROS#ros1

==== RVK ====
http://www.ps3devwiki.com/wiki/Flash:Revoke_Program<br />
http://www.ps3devwiki.com/wiki/Flash:Revoke_Package

==== Second Region ====
http://www.ps3devwiki.com/wiki/Flash:0FACE0FF_DEADFACE

==== CELL_EXTNOR_AREA ====
http://www.ps3devwiki.com/wiki/Flash:CELL_EXTNOR_AREA

search for your HDD brand ( ctrl+f and in text mode type the disk brand) or else ctrl + g and it sould be on the 00F20200 offset



these are the basic steps to check your dump file, however if you wish to go further and check your dump more in dept, please check: <br />
* http://www.ps3devwiki.com/wiki/E3<br />
* http://www.ps3devwiki.com/wiki/Flash<br />

After Checking all those fields, if everything checks, so your dump is OK and you're good to proceed with your flashing process.
always make more than 1 backup of your bios. 


all the credits for this tutorial goes to the @p users of irc channel #ps3downgrade at Ef.net especially to alex07 and eussNL who taught me 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 everything down for further use. after writing everything done i thought it could be useful for everyone.
hope it helps.<br />

Feel free to correct any bad english or any mistaken info in this how to.

best regards cfcolaco

== Would you like me to update my BwE NOR Validator for 2018? ==

Please provide me with the relevant MD5's within ros0/1 etc and I will be happy to do this.

It would take me far too long to do this myself and I am busy with the PS4 NOR Validator.

Here is what is in the latest BwE NOR Validator, as you can see beyond 4.31 is not included:
