What I am going to do here is attempt at creating a listing of known error codes for the PS3 and the PS3 network. The idea is there will be a master list where people can go to see what the code means before they try to talk to Sony support or create threads that have already been discussed. I'm starting off with my first one. If you have others, post them... It you know what they mean or what you did to fix them, post that as well. I will keep this thread updated and hopefully we can start building a knowledge base.
