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
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.
