HD2 Windows Phone 7

Things you will need

1. HTC HD2 that is charged to at least 50%.
2. Data sync cable.
3. If you are on Win XP, you must have Active Snyc installed. Vista and Win7 dont need additional software.
4. SD Card (the card will be formatted!).
5. Only some Radio's seem to work. I used 2.15.50.14 (Download from here).
6. Download the WP7 ROM and MAGDLR from here.
7. Make sure you have HardSPL on your HD2. You can read about what it is and download it from XDA Forums.
8. Bottle of Mountain Dew.

Installation Steps

1. Connect your HD2 to your PC. Make sure the Connection Type is set to ActiveSync (these options usually pop up on your phone when connect the cable.
2. To check if its connected via ActiveSnyc, Windows Mobile Device Center should pop up (for Win7 and Vista users) or MS ActiveSync should pop up (for XP users).
3. Open up the folder where you saved the Radio. Double click the CustomRUU.exe
4. Follow the on-screen instructions.
5. After the reboot, open the Win7 ROM file you downloaded above. There should be 2 folders. Open the MAGLDR112 first. Run the ROMUpdateUtility.exe.
6. Follow the on-screen instructions.
7. Once it reboots again, it will go into MAGDLR...after a few seconds, you will see a list of options. Use the Volume rocker to move down to the 5th option (USB Flasher) and select it. It will then say "Waiting for USB"
8. Open up the Win7 ROM rar and open the LEO70_ROM folder. Run DWI.exe
9. Follow the on-screen instructions.
10. If you did all of the above, when the last step is complete, the phone should boot into Windows Phone 7 !!! Enjoy...

Troubleshooting

Here are some of the problems I ran into whilst flashing

1. When it was loading WP7, on the phone it goes through 4 steps...mine failed at step 4...some formatting error. To fix this, you need to re-load your original ROM and start again from step 1 above. Before proceeding, take out your Micro SD and plug it into your PC and format it. That helped me.
