[Guide] How to install Windows Phone 7 on HTC HD 2

Even though the HTC HD2 is a fairly new device, it never got a chance to go beyond Windows Mobile 6.5 update. The hardware keys on the device were blamed for this, even though the internal hardware itself was capable of running Windows Phone 7.

Now we have a guide that will show you how to install Microsoft's Windows Phone 7 on your HTC HD 2.

[NOTE] This process involves installing a custom ROM on hardware that may not have been originally intended for the software. The guide is recommended for advanced users only who understand the implications of installing custom ROMS. This process may result in your device getting bricked and this site or the creators of the port should not be held responsible for it.

[NOTE] When installing WP7 your SD Card will be formatted during the installation process. Please make sure that you have made a backup of your SD Card prior to installing.
