gilbert, 06 Apr 2015it tells me jar invalid when i want to download games please what can i do to solve the problem*#52828378# is the code to change some java things. go to number 6 put a bigger number than back an try again but everthing will be back to normal after shutting down the phone. if it does not work go to google and search 220*176 games you will have all games suported by your phone.
Connected with PC always appear on my screen can't Make call what do I do?
