Brothers, if you have update 13.52, do not update to 14.00, because after a while you will be able to modify the PlayStation, and currently there is a modification for 13.52, but it is not stable, but it works. The method is very easy. Whoever wants to modify the PlayStation must have the update below 14.00, and I will explain to you how to modify it and give me for my effort, contact me privately.
