Ever wondered how to update your beloved Nokia Lumia to Windows 10 Mobile in 2026? This is the right place for you. In this page you will be guided, step by step, into achieving this skill.
Requirements:
A computer running Windows 10/11
A Windows 10 Mobile compatible device with OS version 8.10.14219.341 or newer
Micro USB data cable
DISCLAIMER:
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm
app failed. Please do some research if you have any concerns
about doing this to your device.
YOU are choosing to do so, and if you point the finger at me
for messing up your device, I won't respond.
Back up your data before following this guide.
Step 1:
Obtain the Universal Updater ".zip" from the "requirements" section. Then, extract it into a folder
Step 2: The real magic
Plug your phone into the computer and run "UniversalUpdater.exe"
Once there, press "1" on your keyboard to select the first option
Here it will be asked for you to choose between different builds of Windows 10 Mobile. You need to choose the right one for you. In my case, the 2nd option was the most recent one, so I chose that by hitting "2" on my keyboard.
The update packages will then start to download. Progress can be seen in the title of the terminal window itself. Click on "run" when prompted
Wait for the update packages to be pushed into the phone. You can check progress in the "settings" app of your device, under the updates menu. Do not unplug your phone.
Once it has finished, an informative window will appear, showing you all the possbile error codes. Don't worry becuase none of these errors will hurt the phone. If some of these happen, just try again.
Wait until the phone reboots.
The update process might take a few hours to complete. I suggest keeping the device plugged in while the gears spin.
Once the update has completed, you wil be greeted with a migration data process. Again, all you have to do is wait for it to finish.
Step 3: Enjoy!
