Hello, I found some problems in my Nokia C3-00 after updating it into v8.70. I can't open/play any application except those original applications from Nokia like Bounce, etc.. I am not also able to open the Store application. Whenever I try to open it, it says that there is a conflicting application which is itself. I asked here before and someone said that I must try to reinstall the firmware. I tried to reinstall but the same problems happen. What should I do now? Please help me to fix this problem. Happy Valentine's Day to all of you.
