Well i can play them after some time, but the PES 2017 Demo that just came out for example i can't ,its only for 4.80 for now,if there is another method...
That's incorrect. You don't have to, if you can't install anything for some reason then you would. It's a last resort. Also, it's named "PS3UPDAT.PUP". With folders and all.
You could resign the eboot, or you can update.
