am really sorry but dont understand,i used the link but theres nowt on then page other than the heading.or am i just being dumb.

Click on the real one, to see whats possible.

yes u can mate
all u need is e3 flasher or progskeet or have some1 to do the job for u

ok cheers for that everyone.

if u need any pdf tutorial for e3 or progskeet shoot me PM bro

I have problem with downgrading 4.25. console is 2504B datecode 0C
in first i try downgrade with normal E3 method(1,2,3,4,5 down 6up) but then console brick, so i solder tristate and flash fun original bios and console power on, then patch with FlowRebuilder but black screen again.
any idea?

Just for my own sanity, I have the old 60 gig Fat PS3 (CECHA01). The banner says the firmware that's downgradable is 4.20, there fore if you were silly enough to upgrade (like my dumb ass) to 4.25, you cannot downgrade to CFW 3.55?

Or if you can downgrade, you need the e3 flasher? I just want it to be clarified because, some of the threads on the forum are a bit confusing, as some say you can't and some say you can.

actually it needs updating
the guides it shows you are now out dated.

if he has a 3000 or certain 2500 model then he will brick his ps3 if he follows this advice!!!

did you use minver checker to see if you could downgrade to 3.55 first before you did anything else?

if you didnt then did you atleast verify your dump (not by using e3's checker as that doesnt actually check anything it should)

can you upload your origional dump to get checked?

quote me so i know you have replied pls

you can downgrade from 4.25
as you have a "phat" ps3 your console can downgrade to 3.55
