PS3 Debug Firmware v3.21 Arrives, Downgrade for OtherOS
Today PS3 Debug Firmware version 3.21 has been added to our PS3 Debug Firmware Archive thanks to an anonymous nice guy, and although it removes OtherOS functionality (like the Retail counterpart did) PlayStation 3 Test unit owners can downgrade to restore OtherOS functionality!
For those who are new to PS3 Debug (DECH) machines or haven't been following our Site News as long, PS3 Test Special Downgrade PUPs were leaked from Sony which allow downgrading the PS3 to version 1.00 or 1.50 (depending on which is used) to restore OtherOS, and then the console can be updated to the PS3 Debug Firmware required to play PS3 game backups.
Perhaps if Sony allowed Retail PS3 systems to downgrade like PS3 Debug/Test machines can there would be fewer lawsuits filed, eh? :p

Below is the official PS3 Debug Firmware v3.21 changelog:
Changes in Release 321.001
Menu of the System Software (GUI)
- The following menu has been deleted.
[Settings] -> [System Settings] -> [Install Other OS]
Check menu in the Game column
- Validation of a media or the file system itself cannot be performed from the Check menu in the Game column. When submitting a master disc, make sure to verify the disc that no error is present using the Disc Image Generator for PlayStation(R)3 or the Disc Image Checker for PlayStation(R)3.
- When performing the check from the Check menu in the Game column, if the number of result files exceeds approximately 80 to 100 depending on each check item, the file entries of the root directory in the USB mass storage run out and the subsequent check result files may no longer be stored. In such case, move the check result files to another directory.
- The system software of the debugging station can be now downgraded to 3.21. Using this update data, you can also downgrade the system software version 3.X0 or later to 3.21.
Note: Please refer to "5 Updating Flash Memory -> Downgrading the Flash Memory" of the "Reference Tool Software Setup Guide" document for more details on downgrading the Flash memory.
Thanks for the quick answer, 700 is reasonable but 1200 is a lot, I guess I got to save up and look for one. Also i know this may seem like a dumb question but how do people get these units? Like does $0ny sell them, or can you apply as a work at home dev and get these units from $0ny.
hmmm... i remember that a user used the hdd-swap method and got a retail-debug-hybride unit...
theoretically we can use this option to downgrade retail units??
Unfortunately using the HDD Swap Method to install Debug Firmware on a Retail PS3 leaves you with just a Retail console with Debug Menu options that don't function. Also, once you do it you are unable to play Blu-ray movies on your Retail PS3 so it's actually worse off in my opinion.
If anyone wants to examine the process, below are links to some guides on it:
They were leaked from Sony long ago to Devs, but more recently the 1.5 Downgrade PUP was also leaked more publically... if memory serves me right, a user in the Debug Forum actually posted on it awhile back.
