How to extract pak file manually [FIGHT NIGHT CHAMPION DLC]

Hi everyone,

is there a chance to extract pak files manually?

There is a problem with the DLC's for Fight Night Champion. The DLC's don't get installed.. Only the update from Ver 1.0 to 1.02 works...

Maybe someone can fix that prolbem.. Another thing is that the update 1.02 sucks.. Maybe there is an opportunity to install the extra boxers that come with the Legendary Heavyweights Pack without update to 1.02? THIS WOULD BE GREAT !!!

There is also a cheat to get the legendary young Foreman.. Anyone knows how to unock him ?

Thanks in advance
