Most of you should already know this trick, but there are still a lot of newbies out there that still haven’t got a clue to access PSN back on 3.55 firmware after Sony introduced 3.56 just recently. So, this post will serve to help those want their PSN back. First, some introductions to the old DNS trick that was revealed after Sony removed OtherOS last year.
Known as Aaron’s DNS trick, it is actually a custom DNS resolver setup which specifically hijacks and directs any IP address resolution request for *.ps3.update.playstation.net to a local web server. The point is to serves a custom hacked updatelist.txt file for all regions that tells the PS3 it’s up-to-date (by telling them them the firmware version 0.00). PS3 will check the required firmware version against its own, which is always higher, and thus upgrade is not required so that you can connect to PSN for online gaming.
The trick is simple, just go to your PS3 menu and follow this steps outlined by videogamegasm.
