okay ive still yet to flash mine as im having hardware issues,anyway..........
the rumour is(and it seems fairly reliable) that the spring M$ dash update will introduce checks for back up games.supposedly wont see the flashed firmware but will see the back up game and stop it booting.
its unknown as to what M$ will do,on the xbox 1 the console was banned from live but obviously its down to M$ on this and live is a bigger part of the 360 experience than it was on the xbox 1.
so if you have upgraded the firmware sort out the 5.3 version,if oyu paid to get it flashed then its up to you whether you want to pay again or take a gamble
