Looking to play mw3 again, unfortunately I don't have any old accounts to bypass the connection to servers problem.
I read about XUID tools but I find it super inconvenient to have to use a computer and tool just to get on.
I know BO2 has some sprx with XUID changers built in.. any SPRX fir MW3 with xuid functions that isn't a tool?
No, I've never seen a sprx with the built-in xuid changer on mw3, unless you create it yourself or someone decides to do it. ^^. Otherwise in the meantime there is my tool on github https://github.com/IgrisModz/Mw3-Fix-Online/releases
