Since the 3.00 update my friends status has been frozen. It keeps saying the same two people are online constantly playing the same games. My PS3's list still works.
Go into safe mode by holding down the PS BUTTON + RIGHT R BUTTON + START BUTTON until it boots up again. Now you will see five options. Choose the REBUILD DATABASE option. This will clean up the bugs and bad files on your ps vita system software that has been built up for a while. You will not lose your game data. You will need to reset your SETTINGS SUCH AS NEAR, MAPS, WIFI PASSWORD, DATE AND TIME ETC. When you start a game after you rebuild the database the system will say that you are playing the video game for the first time but you will have all your data. THE VITA HAS MANY MANY MANY MANY MANY GLITCHES SO YOU ARE NOT THE ONLY ONE. TRUST ME. Well, I hope that I have assisted you and good luck.
