99w 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.

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, ...

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: [Register or Login to view links]

There is also a pkg for uninstall: [Register or Login to view links]

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.

Whenever I try to update to (4.25) I get: An error has occured (8002F827)

I already tried the mirror, gives the same message. Can anyone help me out?

I am on 4.21 DEX right now and wanted to update to 4.25 DEX. I already tried to update from 3.50 and 4.20. Also didn't work

Thanks for that tip, luckily both ps3s already on multiman 04.11.11

I ain't got round to installing it yet. i aint actually turned any of my ps3s on all day. been more interested in seeing if many bans happen over the next 24 hours. (bought a mini model helicopter and i've been playing really i'm only 40)

Also below is a Black Ops 2 - BLES01717 DEX fix 1.02 from beanbaggins stating the following:

I won't try the new DEX CFW yet so I can't confirm that this works online, but it should. I have tested Campaign mode and Zombies first level, and both are working fine on my end.

Also here is a Hitman Absolution Dex patch, tested and working from kittoo:

Ps multiman 4.10.00 or newest version only work proprrly. Upgrade to base or full 4.10 if you use other mm ps3 reboot in red light led

I somewhat agree, but I think the next big thing would be that hard to find exploit for the higher ofw users

Well, I'm stupid - I thought it had something to do with Vita. Otherwise this really isn't too exciting. I guess we've already gotten the "next big thing" anyways.
