PS3 3.56 JFW help

[owen420]

ok guys I am new here and I have followed the ps3 scene for a while but I actually need help

I was on my rebug 3.55 ps3 slim but I upgraded to 3.56 JFW and I loved it so I decided to use the universal MAD downgrader

reason for downgrade: to play psx backups from multiman

3.56 JFW didn't support the latest multiman so I used the the old version that didn't support native psx backups

thing is while I was restoring the R flash back to the ps3 I had a power cut and now everytime I boot the slim it says the firmware can't be run and that I need to upgrade to 3.56 or greater

my question is is there is a software downgrade from 3.56 to 3.55?

I also have a 60GB model on 4.11 kiosk the slim is the 120 GB model released in 2009 not sony's newer model thats meant to be "unjailbreak-able"

any help is welcome

I dont know why you would run that horrible build of firmware lol
