How to force update Nokia Lumia 800 to Windows Phone 7.8

As you know some of us have had no luck getting the official update. So here is a guide to update.

It does three separate updates. Takes about half hour to do all, just leave it be until it says “All Done”.


Read the instructions. They are easy, but their is a disclaimer as with anything like this. Basically you need to download the program and then the Microsoft updater (it does this for you). Extract the updater, and install the 32/64 bit version depending on your windows, and run the original program.

I was shocked by how much extra screen real estate the update gives. I have to admit I didnt like the look at first, but once you resize some tiles and make it your own, it is a vast improvement. It worked for me using a bought unlocked Nokia Lumia 800 on T-Mobile.
