may sound dumb but make sure u connect the cable to the vita correctly bc i had same issue intill i realize i put the cable in wrong make sure the playstation icon on cable is faceing u
I got the same message. I know how to fix it. When you first plug your vita to the ps3, you will get a message on the ps3. Do not press any button on the ps3. If you do, it will take you to the ps3 home page and you will not be able to connect to the vita. If that happens, just unplug the vita from the ps3 and plug it back. You will get the message again on the ps3 tv screen. Now on the vita go to content manager and now it will connect.
