Hi there!

You don't need to install any special PC suite software when connecting your HTC HD2 to your computer. Just connect it using a USB cable and you will be ask to choose the type of USB Connection that you want (Active Sync, Disk Drive or Internet Sharing).

To know more about HTC HD2, you can open this FAQ section of HTC's website.

Best regards!

I'm sorry, but I think you will need to contact T-Mobile for support. Call them from another phone at 1-800-T-Mobile.
If you don't care much about the info on the phone, then do a hard reset to factory defaults.

CAUTION - DOING A HARD RESET, YOU WILL LOSE EVERYTHING ON YOUR PHONE. REMOVE THE MEMORY CARD BEFORE DOING A HARD RESET.

Good Luck,

Hello, what sim network in your phones? Are you still used t-mobile sim card? Or you have change that sim card before? it seems you phones unlocked and you need HTC Touch HD2 unlock code so you can access your phones again. Try call T-mobile customer service and requested HTC unlock code for your phones, this process needs 1-2 weeks before you get that unlock code and don't forget to prepare some money to pay charge from t-mobile. If you need that code immediately you also can buy unlock code from third party sites with lower price and just need to wait a couple minutes.
