Is It Possible to Upgrade from Windows Mobile?
Around ten Windows Phone 7 devices were launched with the platform back in October 2010, with LG, Samsung, HTC and DELL all joining Microsoft to provide handsets for early adopters.
When the platform was first announced, there were hints made unofficially by Microsoft personnel that no Windows Mobile device would be compatible with Windows Phone 7 Series (as it was then called), except the HTC HD2.
The reason for this was the minimum hardware specification for the new mobile platform (such as the 1 GHz Snapdragon processor) which the HTC HD2 surpassed.
After release of Windows Phone 7 in 2010, and the realization that there would be no upgrade path for HTC HD2 owners, several developers began work on porting the platform to the older handset (which shares various specifications with the HTC HD7).

How to Update Windows Mobile 6 to Windows Phone 7 on an HTC HD2
Initial attempts to port the operating system to the HTC HD2 resulted in problems with accessing the Marketplace and Xbox LIVE, however it seems that these issues are now a thing of the past.
Don’t come into this update procedure thinking that it is simple, however. Various software is required in addition to the device to enable it to boot the Windows Phone 7 ROM.
What you will need to for this process:
- A Windows computer with ActiveSync or Windows Mobile Device Center.
- An HTC HD2 phone.
- MAGLDR 1.13 (which in itself also requires that you install HardSPL 2.08 and 220.127.116.11 Radio update).
- Windows Phone 7 ROM for HTC HD2 (find the links in the References section).
Preparing Your HTC HD2 Hard SPL
The first thing to do is to get hold of the HSPL4 file and save it to your computer. Run the application, and note the warning. Next, switch off your HTC HD2.
Holding the volume-down button, press and hold the power button to switch on your handset, keeping the buttons pressed until you see a distinctive four colour striped screen, and then release the buttons.

- SPL 1.42.0000

- SPL 1.66.0000
- SPL 2.07.0000
- SPL 2.08.0000
- SPL 2.10.0000

If none of the above is listed, you probably have a custom Windows Mobile 6.x ROM installed, and will need to install the original ROM for your device.
On your PC, click next in the HSPL4 window, and connect your HTC HD2 phone to your PC via USB. When the phone is recognised, you will be given a drop-down menu to select which HSPL to choose. Select 2.08.HSPL and then click Next.
