hey guys, haven't messed with my ps3 for awhile and am currently on 4.46. I just want to see if I have to do anything special in order to upgrade to 4.70. Do I have to enable Q & A (I kinda remember if your on rebug it does it already) or anything else like that before putting it on a flash drive and doing the system update process? The main reason I want to update is to use my DS4 controller on it. That's in this update correct? thanks!!
