Editing Talk:Playstation Update Package (PUP)

= Playstation Update Package (PUP) - Discussion/Talk =

What is the part that defines, what firmware it really is?. I mean, for firmwares below 3.55 we have all the keys so whe can forge any PUP and make it appear as a +3.55, that would be a way to downgrade, without the need of a dongle and recovery mode.

I know there are version strings in pupheader,version.txt, info0, and in vsh.self.. but what is missing? What isn´t correclty set in mfw to make it pass the checks of a legit +3.55 fw? 

We are using recovery mode to downgrade because, we haven´t found a way to create a legit +3.55

==Adding new keys to older firmwares==

 patch the loaders
 add keys to appldr keys index & tables
 there are also npdrm keys inside appldr as well, add the 3.56++ ones
 appldr,. lv2.self and game_ext_plugin need patching for new games support
 vsh.self maybe too
[http://www.ps3hax.net/showpost.php?p=260186&postcount=14 Creating a MFW? (3.41/3.55 with 3.56 keys)]

# Unrar and copy this MinVerChk PUP to your USB stick (/PS3/UPDATE/PS3UPDAT.PUP), the same way as if it was an firmware upgrade.
# Insert the USB stick into the PS3.
# Start a firmware update like normal from XMB (Don’t worry, it will not update!)
# It will shortly fail and display the Firmware Base Value

Note: console needs to run at least FW 2.50? (2.30 didn't work)

==Repositories==

[http://pubrepo.stoker25.com/Consoles/Playstation%203/updates/ stoker25 - specialises in debug/DEX and DECR/TOOL firmwares] (self hosted)

== Remark @ Installation ==

ps3d storage region 3 on the internal harddisk (ps3dc) is used by the PS3 as temp for installing updates. When installing PUP files, the PUP content gets unpacked there, checked - the system flags the update bit and prompts for reboot. After reboot it sees the update bit set and installs the files from ps3dc without rechecking (!) -> possible attack vector for circumventing checks, like down-/crossgrading). edit-note: doesn't seem to be true, it is still checked.

ps3d - 4 possible regions :
 ps3da : whole disk
   ps3db : UFS2 : GameOS
   ps3dc : FAT (2GB) : Update
   ps3dd : EXT3 : OtherOS (in the <=3.15 way)

== old crossgrading Retail/CEX to Debug/DEX ==
'''Note'''<br />
For this to work your system must be below or at 1.80 for the 1.80 debug update and below or on 2.01 for the 2.15 debug update. Just use the next version up from your current firmware version for the retail update.

It's not very usefull, esp. nowadays, added for historic reasons

===How to install debug firmware on retail PS3===
old source: <span style="text-decoration: line-through;">http://www.ps3hax.net/other-misc-tutorials/4808-tutorial-how-install-debug-firmware-retail-ps3-partially-hdd-swap-method.html</span>

====Tools needed====
* 1 PS3 system
* 2 PS3 hard drives that are the same size
* 1 retail firmware upgrade
* 1.80 Or 2.15 debug firmware

====Instructions====

# Format both hard drives on the PS3 system.
# Download a debug PS3 firmware and place it in USB stick, and start the update. This will copy all the debug firmware files to the PS3's HDD-A.
# After copied the PS3 will restart and you will see the normal update menu which prompts you to click the button to start update. Do NOT update your PS3, but power it off.
# Next remove the HDD-A, and place in the second HDD, HDD-B in the PS3.
# Download and copy a retail PS3 firmware to a USB stick.
# Again as before place USB in PS3 and update the PS3 as normal but when you get to the screen where it asks for you to press button, do that but stop when it asks you to AGREE to Terms and Condition Page.
# While the system is still powered on and on the update screen, REMOVE HDD-B, and insert HDD-A.
# After swapping the HDD's continuie to update the PS3 as normal and the PS3 will install the debug PS3 firmware=
# Go to the settings and check firmware version and there you will also see the debugging PS3 options :)
