My phone went crazy Heeelp!!!

[Loon]

HI. I just down loaded a game from Mobile9. Now i've done this loads of times before without any problems, but now after down loading this latest game my phone, a 6280, has gone crazy. It will switch on ok but then goes crazy with the screen flashing on and off for a few seconds before the phone switches off again. it now goes through this every time I try to switch the the phone on. Does anyone know whats happend and how I can sort it out please.

If your phone doesn't stay on hardware factory reset is impossible. Try reflashing the firmware or bring to the service center to do it for you.
