If i try to update through recovery mode it tells me that their is no applicable update found. When i try through the ps3 OS they both give me error 80029C55So right now your PS3 is on 4.80 Demo mode, and you tried both of these links and it doesn't bring you back to 4.80 OFW (non-Demo) mode?
What happens when you try running them on the PS3 console?
