Apparently, G.I. Joe: Rise of Cobra’s UMD requires the user to update to 5.55. No real word yet on what it updates but surely it blocks the 5 exploits people are working on for 5.50 and 5.51. It’s yet to be confirmed but what we all can agree that this will be bypassed soon as this is a warning that a wave of new updates is coming out.
