Xbox 360 – Which games can i Play with iextreme 1.6?

Hey everyone.
I haven’t used my xbox (phat) for quite some time and thought i’d try fifa 12 for my console.
It has iextreme 1.6 and i used the activate.iso for games like cod:mw2.
If i get a fifa 12 backup, can i play that? My guess would be yes, as it is neither ap 2.5, nor xgd3.
Any help is appreciated!

Probably not (not 100% sure about Fifa 2012). Most of the games released after Q2 2011 require the Spring 2011 dashboard update to play, but installing that dashboard update flashes your firmware back to the stock one.
