My mobile, a Karbonn A4, does not update the system. I open Setting System updates, click “Checking Updates and then I get “Network connection failed, retry?”.

I’ve tried, but no updates on my mobile. WiFi will not update. How can I update my mobile phone?

    Besides Micromax(on its selected phone),no other Indian brands provides updates to its phones.

    perhaps it is not possible to update beyond Android 2.3.6 Gingerbread thus not getting 4 or 4.1 android, perhaps you can install a custom rom like CyanogenMod?

    maybe you can search here

    if decided for custom rom and like to get the stock firmware if something goes wrong check here
