Flashing HD2 : http://forum.xda-developers.com/showthread.php?t=609477

Android on HD2 : How To and Guides :  a MUST read before you try - http://forum.xda-developers.com/showthread.php?t=734335

Android roms  on HD2 : http://forum.xda-developers.com/forumdisplay.php?f=735

This is a quick guide :

First to flash any rom, you must unlock your phone. The process is called HSPL. You can refer here how to do it:
( A) http://forum.xda-developers.com/showthread.php?t=609477

HSPL is the only process where you are likely to brick your phone. These are the few things you must take note: Battery at least 70% charge, SD card and Sim card must be taken out - usually bricking is due to this mistake of not heeding these 3 factors

Once your unit is HSPL, you can proceed to do the Android port

1. You have a choice to keep your Windows rom or change to another . If you want to change the Windows rom - instruction is at above XDA link ( A )

2. The port to Android instructions : ( B)  http://forum.xda-developers.com/showthread.php?t=732380

I always advise all to spend time reading these links - don't jump into it. Have a understanding first.

TIPS :
- Make sure Radio is 2.08 and above ; how to flash radio - link ( A) : Flash radio will not delete your phone data
- SD CARD : Freshly format it using this tool at  http://www.sdcard.org/consumers/formatter/sdfv2000.zip
