Either use PSgrade/JIG and let the lv2diag.self be executed by lv1.self automaticly, or use MultiMAN self loader<br />

Tested working on CECHG fat (256MB NAND). I suspect the reason for people bricking was they were flashing dumps of different lenghts and offsets (such as from memdump) and not the one provided by dumping with ?this?. -sk1080

== NOR guide ==


# Put above mentioned 3 packages in root of USB stick and install them on the PS3 using *Install Packages*
= EID correctness =
# With the USB stick still inserted, run Memdump v 0.01 and select the option "Dump Flash Storage"
# Run eEID_RKDumper. It should give 5-10 seconds black screen, beep and shutdown the console.
# Reboot the console, start MultiMan and use the filemanager to navigate to /dev_hdd0/tmp/eid_root_key and copy this file to the root of your USB stick.
# Now you should have the PCK1 (eid_root_key) and complete flash dump (flash_stor_35500.bin) of that console. Backup these 2 files for safe keeping/debricking. If you have multiple consoles, mark them as needed (e.g. serial from white sticker) to avoid confusion.


<!--// 7. download Cex2Dex.exe and place it on your desktop load the flash_stor_35500.bin for the top and rename eid_root_key to dump and load that for the bottom, next click on cex to dex.
  [8/31/2011 1:41:13 AM] xxxxxxxxxxxxxx: the information on the PS3 dev wiki was intentionally faulty
8. If all went to plan then it will ask you to save your converted flash as my-DEX-flash.EID0.NORBIN
  [8/31/2011 1:41:15 AM] qqqqq: Use the creativity or fail to find it.
9. place that file on your usb (I suggest removing other files to avoid accidental flash) so you have my-DEX-flash.EID0.NORBIN on the usb.
[...]
10.Open multiman file manager and locate the my-DEX-flash.EID0.NORBIN on your usb and click it it will go through 3 pages of verification just press x on each page
  [8/31/2011 1:41:34 AM] xxxxxxxxxxxxxx: so people can't use the 'knowledge'
Note: you must start Multiman in debug mode by holding the triggers as you start or restart MM and then update MM. Running the NORBIN file now brings up the prompts about overwriting your flash and not the HEX viewer
[...]
11. Reboot ps3, and you will be able to install any Dex Firmware //-->
  [8/31/2011 1:41:43 AM] qqqqq: xxxxxx, uuuu has done a very good job at fixing what IS wrong. If you saw something wrong, why didn't you ask uuuu about it to fix it?
  [8/31/2011 1:41:55 AM] xxxxxxxxxxxxxx: that's not what guys like rrrrrrr have told me
  [8/31/2011 1:41:58 AM] xxxxxxxxxxxxxx: it's intentionally faulty
  [8/31/2011 1:42:03 AM] qqqqq: Instead you left it  how it was and bitched about it.
  [8/31/2011 1:42:07 AM] xxxxxxxxxxxxxx: to prevent any meaningful extraction of keys
  [8/31/2011 1:42:11 AM] qqqqq: If it was fault again talk to uuuu
  [8/31/2011 1:42:24 AM] xxxxxxxxxxxxxx: no - uuuu could not have even known about it
  [8/31/2011 1:42:28 AM] xxxxxxxxxxxxxx: it was something only a kkkk could know
  [8/31/2011 1:42:45 AM] qqqqq: You'd be surprised what uuuu knows. he really is a walking encyclopedia of the ps3.
  [8/31/2011 1:42:48 AM] xxxxxxxxxxxxxx: that wiki is compromised with purposeful misinformation
  [8/31/2011 1:42:59 AM] xxxxxxxxxxxxxx: and that's what rrrrrrr actually said and thinks
  [8/31/2011 1:43:17 AM] xxxxxxxxxxxxxx: I'm talking about ps3 dev wiki BTW here
  [8/31/2011 1:43:25 AM] qqqqq: if it's providing false info, then why not make a site to provide the right info? *gasps*
  [8/31/2011 1:43:34 AM] xxxxxxxxxxxxxx: well he did make the suggestion
  [8/31/2011 1:43:38 AM] xxxxxxxxxxxxxx: but it didn't go over well with these people
  [8/31/2011 1:43:45 AM] yyyyyyyy: kkkk wasn't the only one with cex-dex shit
  [8/31/2011 1:43:50 AM] yyyyyyyy: hell he's not even the one who wrote it
  [8/31/2011 1:44:01 AM] yyyyyyyy: so you can stfu about that
  [8/31/2011 1:44:09 AM] xxxxxxxxxxxxxx: hell do I know who the fuck wrote CEX-DEX
  [8/31/2011 1:44:27 AM] xxxxxxxxxxxxxx: all I know is that there are a bunch of connivant shits that want a wiki intentionally 'disinfoed' like that
  [8/31/2011 1:44:35 AM] xxxxxxxxxxxxxx: people in the know
  [8/31/2011 1:44:49 AM] yyyyyyyy: and one conniving shit here trying to save his hide
  [8/31/2011 1:44:57 AM] qqqqq: xxxxxx, again as i said. If there was false info (Which uuuu would never do) Why not fix it
  [8/31/2011 1:45:21 AM] xxxxxxxxxxxxxx: go ask rrrrrrr - I dunno
  [8/31/2011 1:45:26 AM] qqqqq: DO you think he purposesly makes changes so that it's wrong? That'd create an even bigger headache if a noob attempted it and bugged us in the chat
  [8/31/2011 1:45:32 AM] xxxxxxxxxxxxxx: the EID/CEX-DEX info was incomplete
  [8/31/2011 1:45:33 AM] xxxxxxxxxxxxxx: faulty

If you are getting trophy errors preventing you to play backups then make sure you perform the following steps:
# Go to recovery menu and restore default settings.
# Rebuild ps3 database from recovery menu.
# If you had a playstation id then add the playstation id/password in the playstation network settings. Try to connect once. It will ask you to upgrade your console. DO NOT upgrade! Keep the playstation id/password saved in the psn settings.

Neither the [[SC_EEPROM#EEPROM Offset Table - Flags and Tokens|FSELF Control Flag nor the Debug Support Flag]] is changed, nevertheless, no functions of the DEX firmware are restricted, it behaves like a original one. Sony could just add checks in the upcoming DEX firmwares and patch this CEX2DEX conversion method. Also this isn't a full CEX-DEX conversion, seeing as the IDPS is changed only in EID0 and not also in EID5.

# use Recover or Factory Service Mode to install Rogero 3.55 V7 PUP (the basic downgrader that is always used to downgrade consoles)
# on install success, activate QA and do buttoncombo to check QA-debug menu comes up. then goto Recovery and install OFW 3.55 CEX /twice/ in a row, to make sure both banks are dehashed
