ok so the fat 40gb ps3 i'm trying to fix has had several ylod's that i've fixed. latest one i done the 12v fan mod/ fans are running 100% now so seems to be fixing the ylod so far/i've came across several new problems tho first one and most worrying is that controllers wifi and ethernet aint working/syncing i get some connection error code.

i've tried reseating the wifi cards ribbon ect still no go/i thought i would try to downgrade back to ofw 3.55 to see if that helps but it gets to 70+% and errors so have to reformat in pc then reupdate to rogero latest any advice on either on these would help.
