Sony PS3 Debug / Test (DEX) Firmware 4.21 Update Surfaces


84w ago - Following up on the PS3 Debug Firmware 4.20 and PS3 Test Firmware 1.01 & 1.02 updates, this weekend an anonymous user on the PlayStation 3 Developer Wiki has shared the Sony PS3 Debug / Test (DEX) Firmware 4.21 update for collectors.

Download: PS3 Debug / Test (DEX) Firmware 4.21 / PS3 Debug / Test (DEX) Firmware 4.21 (Mirror) / PS3 DEX 4.21 VSH Dump by tjhooker73 / PS3 DEX 4.21 VSH.self to VSH.elf Decrypted by itskamel / PS3 LV1 4.21 DEX & LV1 4.31 CEX by Rancid-o

As always, keep in mind these PUP updates will currently NOT install on a retail PS3, and so they are intended for examination and comparison purposes only.

We have 100% confirmed that running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported. (8002F029)

To quote: File changes compared to 4.20 - These files have changed since the previous version e.g. by new version string, bug/crash/exploit fixes, ...

PUP Hashes

Pup Information

Finally, in related news below is a PS3 Restore Utility Backup / Restore DEX Console Guide (via ps3ita.it/hack/ripristino-utilita-di-backuprestoresu-console-dex-by-ps3ita/):

After making the conversion of the PS3 console from retail (CEX) in debug (DEX), some may have noticed the lack of utility of backup / restore (accessible from Settings -> System Settings -> Backup Utility) that allowed you to save all content (accounts, photos, music, games, etc. with the exception of trophies) on external media to back recovery in case of failure / change of the internal hard disk.

Therefore PS3ITA, thanks to our mythical Rancid-o, provides a simple method to restore such function by means of easily installable file pkg.

We found a way to restore Backup Utility in DEX:

Just install and start this pkg: http://uploading.com/files/get/5dd48caa/Restore_backup_utility.pkg

There is also a pkg for uninstall: http://uploading.com/files/get/c7ff884f/Uninstall_backup_utility.pkg

This is because if the option backup utility does not uninstall many options are not displayed in "debug settings". Oh I forgot has only been tested on cfw 3.55 DEX.

Lol HeyMan did that rep from the boss go to your head? (Sarcasm)

And if your referring to me "This guy can see in the future," then I do agree it dose seem that way going by some of my posts five month ago when I said how I thought some things will turn out. And they have.

"The people in history who said "never" are rarely, if ever, remembered..." thats why people like me don't ever use their real name, and don't wish to be remembered.

In fact in the 25 years of using the net or computers I have never used my real name or address. lol. so No I don't wish to be remembered. nor found. lol

Tragedy, you say there is a way to downgrade from 3.56 to 3.55. Is this something you have done yourself? or read that someone has done this?

Because as I understand this, its just not passable unless the master base firmware has been leaked or created giving you the option to install the original firmware that said unit was shipped with, then upgrade back up to any ver you like.

The pups that we install are upgrades patches, hence the small size of only 180 megs ish, the full flash can be anything up to 250 odd megs in size depending on what unit it is, and it dose use some of the drive for storage, as you may or may not know.

So if you wanted to downgrade from 3.56 to 3.55 you would have to reinstall right back from the beginning to replace what was removed and locked in 3.55 and 3.56 and above.

Once you go past the 1st release of 3.55 it is game over, because home-brew will not work past 3.55 nor will blue rays on modded firmware. I believe that apples to debug and rebug as well, So backed up games is over if your over 3.55. Sad but true!
