1 - Ditch the donlge is it useless.
2 - Install 3.55 OFW
3 - Go into recovery menu and install Kmeaw CFW 3.55
This way there is no need for a dongle or hacked ebbots that are a pain in the butt and best of all no need to toggle power and you will not lose ANYTHING doing this game data wise, you will lose a crappy lived past it's life dongle. CFW is where it is at now as with it and Multiman there is now a 99.5% successful boot rate and it is as easy a can be. Best of all with this you can get back on PSN. Or if you like 3.41 for some strange reason at least install hermes 3.41 cfw so you can ditch the dongle.
