How To Install Windows Phone 7 On HTC HD2 With MAGLDR

HTC HD2 Windows Phone 7While we have previously covered installing Windows Phone 7 on HTC HD2, we didn’t have a chance to try it out ourselves then but over the past few weeks, we have been playing around with our HD2 quite extensively including Windows Phone 7 installation. That’s why we are bringing you a whole series of guides in a much more organized way to help you make the best out of your HTC HD2. Read on for more details and the complete installation instructions.

The previous guide still contains valuable information as we were amongst the first to cover it when Windows Phone 7 for the HTC HD2 was news. For this reason, we will not be replicating the information about the ROM itself from that guide into this one and you can see it as well as the videos demonstrating it there directly by checking out our previous post on installing Windows Phone 7 on HTC HD2.

However, that post should now just serve as information on the ROM and not as the installation guide, as we are attempting to significantly organize all information on the HTC HD2 and its hacks and that involves splitting guides into multiple ones because a part of them is relevant in other hacks as well, and also because the primary tool used in our old guide i.e. MAGLDR has been updated and the newer version have more to offer that needs to be highlighted.

Once you have checked out that post for the information on Windows Phone 7 for the HTC HD2, you may continue reading here for getting it up and running on your device.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.



  1. Download the ROM and extract its contents to your computer.
  2. Power your HTC HD2 off and boot it into MAGLDR menu by long-pressing the Power button.
  3. Select USB Flasher mode.
  4. Connect your phone to the PC via USB.
  5. Launch DWI.exe from the files extracted in step 1.
  6. Follow any on-screen instructions carefully to flash the ROM to the HD2.
  7. Once the installation is complete, the phone will automatically reboot into Windows Phone 7.

Congratulations! You should now be running Windows Phone 7 on your HTC HD2.

Note: If you want to dual-boot your HD2 with both Windows Phone 7 and Android, you need to configure your SD card first. See how to dual-boot Windows Phone 7 and Android on HTC HD2.

Later on, we will be featuring a complete guide on how unlock and enable app sideloading as well as Marketplace access on your HD2 running Windows Phone 7 and will be updating the links here so stay tuned!


  1. I know this is practically more than two years later but I recently “stumbled” across an HTC HD2 (what a great phone, btw) and wanted to put WinPhone7 on it. It is a T-Mobile branded device with the latest official ROM and the recommended by you radio. I have also installed HSPL v.2.08 and MAGLDR 1.3 with no problem, everything went fine, per your instructions in other articles. However, the link for the WP7 rom is broken and I am stuck at a point where I boot my phone into MAGLDR menu but nothing after that. I wish I could at least be able to boot into the original Windows Mobile 6.5 but that was wiped out after installing MAGLDR. So what can I do now? Can you help? I’d like to try WP7 but if I can’t find it I’ll settle for 6.5. Finally, what is the highest version the HTC HD2 will run without problems? 7 or 7.5 or even 7.8? Can you please help? Thank you!

  2. I am trying to install windows 7 on my HTC HD2. The installation of MAGLDR worked fine, now the installation stops point 4. The program tells me there are some errors and I have to take my battery out to restart the phone. Then it starts with windows 7 but says that there is a problem with my SD card. I am using a SanDisk 2gb micro SD. Can anyone help me?

    • Yes, I know what’s wrong. Before you do step 3: Select USB Flasher mode, boot into MAGLDR and go to 10: Services then select 4: UseLast24NAND.
      Then Step 3, it should work fine now.

    • I have the same problem but when i want to boot from MAGLDR it says booting whp 12345 GO GO !! I dont have the menu from where i can choose 4: Uselast24Nand … Please help me

  3. @facebook-532709722:disqus: How can I format and reinstall WP7 on Internal Memory i.e. to fresh install as default OS? Plz help me.

    • Hey, if you follow the instructions on this blog it’ll install as your default OS (the ONLY OS actually) on your internal memory.

  4. I cant download WinMo 7 Rom. The link given above leads to some Anti-piracy warning page 🙁
    Please help me with a new link to download winmo 7 Rom..

  5. We followed the procedure but only get the white HTC boot up screen. I’d really appreciate any advice on how we can return the phone to a working version of Windows. Many thanks.

    • Just flash a stock 6.5 ROM from the HTC website. 6.5 Market Place is being discontinued you know? What ROM did you flash? It sounds like you’ve done something wrong because I’ve done a few of these and they’ve all worked fine, in fact I’m using one now because I genuinely love it.

      I would say give it another go:
      1. Task29

      2. Install Magldr

      3. When boot to magldr menu, go to:

      * 10. Services, 4. UseLast24NAND

      * 10. Services, 5. ClearSD MDR

      * go to 5. USB Flasher and run DWI.exe to flash ROM

    • Thanks for your help, Jeff.

      We installed the MAGLDR as yesterday but the phone now switches on immediately to the white HTC screen and a long press of the power button doesn’t bring up the boot menu.

      Can you tell me what is Task29 and DWI.exe is,please.

      Your help is greatly appreciated.


    • Did you install HSPL 2.08? You need to install 2.08 for this to work, when you install HSPL there is a dropdown menu and you need to select the correct version. Check which version you installed (make sure it installed properly) by turning the phone off and holding the ‘volume down’ key when you restart until you reach a tri-colour screen.

      It should say:
      SPL-2.08.HSPL on the second line down with some other stuff, if it doesn’t you need to reinstall it and then reinstall MAGLDR.

      Task 29 formats your phone memory (=binfs). It prevents weird error appearance when you flash new ROMS. But you’re not getting as far as flashing the new ROM so I’d not worry about that at the moment.

      DWI.exe is the file that you execute when you flash your new ROM.

  6. Has the unofficial WP7 been purged from everywhere or just within the US? Just wondering because I’m a Norwegian citizen originally, and wondered if it’s still available out there?

  7. Is there a new link to the Windows 7 ROM now Megaupload has been wiped of the face of the planet by the fascists?

  8. oh, it’s ok now ;D i just need to plug the USB cable in AFTER launching DWI.exe, when it’s waiting for it ;D not like this:
    Select USB Flasher mode.Connect your phone to the PC via USB.Launch DWI.exe from the files extracted in step 1.

  9. An error has occurred
    Read below for more information

    Error Description: USB init failed
    Info: .RSPLRSPL.cpp (1198)

  10. I installed and on reboot it goes to a DFT splash screen and just sits ther. It did once boot to WinPh7 and I was connecting to my wireless network when it rebooted back to the DFT splash screen. Now stuck there.
    Can anyone help?

    • Well its booting now and tweaking the APN settings got my mobile internet working. But I can’t take pictures or store any data as it says there is no room. Also can’t sync with WMDC or ActiveSync. Device is not recognised. Device Manager shows no driver is installed and can’t get one. I would like to roll back but beecause WMDC wont connect, I can’t update the ROM. Is there another way? Help….

  11. Error Description: USB init failed

  18. I just ran across your article on installing Win 7 Mobile. I got the courage up to do it yesterday. Well, I follow your instructions to the “T” and everything came out just fine. The only problem I had was I needed to add the APN to the Cellular section. I have T-Mobile also so it just picked it right up and Internet Explorer is working just fine. The process was pretty easy actually.

  35. GREAT Build!

    I’ve had HD2 since it was released and I have to say I never enjoyed it more than I do now with the WM7 build.
    I have ported it to Android 2.1 and 2.2 along with WM6.5 but WM7 is so far the best!

    Everything is functioning correctly except for a small annoyance which is LED notifications! I haven’t been able to find a fix for it to make LED notification appear for missed calls, SMS, emails etc… It is not a big deal but I will definitely be coming back to check any updates you post on here.

    Again great job on this and thanks.

    Here is some links that I found very helpful after installing WM7 on my HD2.

  36. I did this and my interent explorer is not working –

    It reads:

    Action Was Canceled

    We couldn’t open the page. It may be temporarily unavailable,

    My location is turned on
    Active Netowork reads: T-Mobile
    Data Connection: ON
    3G Connection: ON
    Network Selection: Automatic.

    Is there a way I can set the internet to operate on windows 7 for my HD2?
