Windows Phone – Force Windows Phone v7.8 to the Nokia Lumia 800

I successfully updated my phone to Windows Phone v7.8 (see this blog post), but on another Nokia Lumia 800 I wasn’t able to with Zune. Therefore I needed to crack this to force an update of the files from the Nokia update server.

Below are the steps to follow to force the download of Windows Phone v7.8 (v7.10.8858.136) to your Nokia Lumia 800. I found the steps I have created to be a bit ‘fiddly’, but it does work eventually. Make sure you have Zune installed first!

  1. Turn on Flight Mode on your Nokia Lumia 800 (Settings > Flight Mode > ON)
  2. Connect you mobile to your PC via USB cable. Zune should start automatically
  3. Sign into your hotmail/live account you used to setup your Nokia Lumia 800
  4. Make sure you have an active internet connection, I will be using my WiFi connection for this step-by-step process.
  5. Click Settings. Located at the top of the Zune application.
  6. Click Update. Now this is where the fun starts! When you see the message below, count to 5-6 seconds and DISABLE your WiFi connection i.e. kill your internet connection! (Note: disable your LAN connection if you are on a wired connection.

Checking for updates

  • Now you should see an update is available message. ENABLE your WiFi connection and proceed to install the update. YOU MUST ENABLE YOUR INTERNET! This force process only does the updates 1 by 1 – yea painful! So therefore once the first update is complete, you will need to disconnect your phone and then REPEAT steps 1-6 again.

Zune Update Available

You will find there are 3 updates available to get to v7.10.8858.136:

  • 7.10.8779.8
  • 7.10.8783.12
  • Nokia Update for Windows Phone

Things don’t always work to plan right? Here is what you do if you get one of the messages below instead of the update is available message.

  • “Your phone is up to date” –> You weren’t quick enough disconnecting your WiFi or LAN connection
  • “Zune can’t connect right now try later” –> You were to quick disconnecting your WiFi or LAN connection

Can't check for updates right now

Message you will see for update v7.10.8783.12 (second update)

Zune Update Available -2nd

Message you will see for update v7.10.8858.136 (final update – Windows Phone v7.8!)Zune Update Available -3rd

Not the best process I know, but I hope that helps?

P.S. remember to turn off Flight Mode once your done.

    Any idea if this will work on other WP7 devices such as a HTC Titan
