Install Windows Phone 7.5 Mango Build 7712 [Any WP7 phone]

Microsoft released Build 7712 of Mango update for their Windows Phone 7 mobile operating system, it comes with 500 new features, you can now install Windows Phone 7.5 latest build (7712) Mango on any WP7 Phone using this guide.

You need not have a developer account in order to proceed with the installation.

How it works: This methodology fakes necessary parameters to make Microsoft’s update service believe that you’re using a developer phone so that the developer-only Build 7712 update gets pushed to you and your phone.

  • WP7 Phone with NoDo update (copy-paste update)
  • Updating tool
  • 32bit or 64bit support tools.
  • Windows PC (Vista or 7).

How to Install Windows Phone 7.5 Mango on any WP7 Phone

Step 1: Before we begin, make sure Zune software is not running. Extract the “updating tool” you downloaded and run update.bat as an administrator (right click, run as admin).

Step 2: Once finished with fooling stuff, Zune would launch from which you will have to check for updates.

Step 3: Zune might show you Build 7401 download & install, Check for updates again and you will see Windows Phone 7 Build 7661, download and install this too. Once done, your Zune will not recognize your phone, you will need to download and install a beta version of Zune from here.

Step 4: Check for updates the 3rd time and you will get the Windows Phone 7 Build 7712 ( oh yeah that’s how it works) again, download and install.

That’s all, you now have the latest Mango build running on your phone.

Downgrade to WP7 NoDo

If you run into trouble or don’t like Mango for any reasons, run restore.bat as admin and you should go back to NoDo.
