Force Windows Phone 7.5 Mango Update

Last week I was pleasantly surprised to be notified by my phone (HTC HD7) that the Windows Phone 7.5 Mango update was available. Of course being a cautious, patient end-user, I rushed to my desktop to sync my phone and installed the update. I've been impressed with Windows Phone 7 since I switched from the iPhone in February - it didn't have certain features I had grown accustomed to on my iPhone, but I reminded myself that the iPhone didn't have those features when I switched to it either. And sure enough, over time, Microsoft has made consistent improvements to the OS and has made it a real contender in the Mobile market. Now, I knew that I was going to be pleased with the features added by Mango, but I didn't think it was going to be a 100% improvement over an already decent platform. Somewhere during my raving about the added features and improved performance I realized that my wife's HD7 had yet to notify her of an available update. Hmm . . . trouble in K-Town.

After some searching I came upon the unlikely recommendations over at

  1. Connect your Windows Phone to a PC and launch the Zune client
  2. Click on Phone/Settings/Update. Allow the software to tell you whether an update is available. If so, skip this guide. If not continue to the next step.
  3. Click the update button again, and this time immediately disconnect your computer from the internet (some people have better luck waiting 1-2 seconds). Do this by pulling the Ethernet cable, disabling Wi-Fi and ensuring there is no Internet connection.
  4. After around 30 seconds or so you should receive a notification that an update is available. This is 7392, a post-NoDo security update.
  5. Connect your machine back to the internet and continue with the update process through the Zune client
  6. After 7392 is fully installed, you may receive a notification that another update is available. If so, install Mango now. If not, proceed to the next step.
  7. If the second update isn’t popping up on its own, repeat steps 3-5, causing the 7403 update to appear.
  8. Install 7403
  9. After 7403 is installed, Zune should automatically start installing 7720, Mango. If it doesn’t happen automatically, force it using steps 3-5 once again
  10. Windows Phone 7.5 “Mango” installed
It worked on the first try for me - my wife's phone is updated and my marriage is left intact. Now I'm just waiting for T-Mobile to release that firmware update to enable wifi sharing . . .
