New HDD
Downgrade update on USB and in either slot one or two.
Power on the PS3
It says to connect controller with USB
Then it looks for and finds the downgrade update
The counter goes to 100% and the screen goes blank (restarting? I don't touch anything)
When it comes back on it says to connect the controller wirelessly.
As soon as I click the PS button it will be a few seconds and the data corrupt message comes on and it says to press the circle.
And that's as far as it will go.

***right here, pull out the usb, delete that firmware on the drive, and put the rogero cfw 3.55 v3.7 where the other firmware was (USB/PS3/UPDATE/PS3UPDAT.PUP)***

Model №: CECH-2504B
Datacode: 0C
Base FW: 3.40FW
Firmware History: OFW 3.55(Rec)->KMEAW 3.55(Rec)->Rebug 3.55(Rec)->OFW 3.55(XMB)->KMEAW 3.55(XMB)->Rebug 3.55(XMB)->KMEAW 3.55(XMB)->Rogero 4.21(Rec)
Before installation, disabled 4.25 spoofer by SGK, copied back original CA27.cer then I installed Rogero's 4.21CFW to PS3 Through Recovery Mode
CFW Works normally i think. PSN, PShome all works for now.
Important: Backuped my NOR Flash dump to 2 flash drives for safety of my PS3
and now, I got questions about new CFW's on 4.21 that will be in future, we must first to downgrade to 3.55 to install new versions of CFW 4.21, or we can install them over CFW 4.21?
and question about downgrade, did you tested that downgrade method on your ps3 and how it was? dumb question for real but if you can answer, answer please
Thx for CFW again

I had another usb drive with 3.55 cfw on, I've tried swapping them quickly, switching it off after the 100%.
it's not playing at all
