25w ago - Nearly two months after the
previous update, today I have posted a guide and video on how to downgrade a PS3 4.31 OFW console (including
CECH-300x slims) to
4.30 Rogero v2.03 CFW using a PS3 Hardware Flasher with no 3.55 needed.
Very easy tutorial. Follow the steps to downgrade a PS3, but when you get to the first step of the USB downgrading part after putting your PS3 into service mode, use Rogero 4.30 CFW v2.03 on the root of the USB with the lv2diag.self to downgrade instead of the 3.55.
So again, no 3.55 ever touches the PS3 during this whole setup! Doing this will also now allow CECH-300x models original slims to be downgraded to 4.30 CFW as long as it never touches 3.55
The whole reason for this was to find out if the E3 fits a CECH-400xx model super slim models, but all I needed was proof that you can downgrade from 4.31 to 4.30 CFW with a flasher.
So if any one out there has an E3 and a new super slim model please test this if it works! You can make back ups of the NOR incase it fails.
Here is proof you can but I still do...

I saw it right after I made the thread, sorry about that.
An offshoot question, does it matter what version is used for the 3.41 JB?...
