  • How are you connected to the internet? It needs to be over a data connection, not Wi-Fi. Oct 24, 2011 at 14:12
  • Seconded - I've tried over a data connection as well as WiFi. Same error. Hoping for an update for India from the current 2.3.3

Galaxy S2 doesn't support OTA updates...so it's unlikely that you will be able to check for updates from your phone. The same "Connection Failed" error comes to me when I try that in my phone.

  • then what are the other ways to update the phone software?

    @emaillenin download Kies for your computer and connect the phone via USB, it should prompt you for updating.
