Can't install ofw on my jailbroken ps3 fat CECHA after full factory reset for a jailbreak refresh.

I would like to factory reset and install ofw 4.84 from rebug 4.84 so can rejailbreak it to the latest evilnat 4.91 and play ps3,ps2,ps1 from iso on an external ntfs drive. It's being slow and I think I messed something up so I want to start from scratch again to to see if that works and fix ps2 iso from not booting.

I tried to do a quick and full formatt in the system settings but it keeps going back to rebug 4.84. Can anyone help me with this that would be great.
