Microsoft has officially started rolling out Windows Phone 7.5 Mango update to almost all regions as we write. However, you may not be able to see an update notification for your device, since it takes up to four weeks to to get Mango update on your device. Like, NoDo forced update trick, you can trick Microsoft Zune player to present Windows Phone 7.5 Mango update on your device, even if it is not available in your region (it is not available in India as we write).

Zune can be tricked into providing the Mango update right away. Before you move on to follow the entire procedure make sure you read the given instruction twice. You should also charge your mobile battery to 50% or higher, make sure that you have enough power supply so the process is not interrupted due to power failure. This is a legit method, in the sense that you’re getting an official update from Microsoft instead of illegal custom ROM.

For those who are already on 7392 pre-mango build should not face any problem. Connect your device to Zune player and update your Windows Phone to latest update (pre-Mango update) if you haven’t done already.
