Windows 10: Error Code 0x800703f1, Windows 10 update failure code

Can someone tell me what Error Code 0x800703f1 means and how to fix it. I have not been able to update Windows 10 due to that error: I have been trying since earlier in 2020.

Windows Update (KB3081455) fails. Error code is 0x800703f1.

Hello.

The OS of my PC is Windows 10.

Windows update of KB3081455 fails every time, and the error code is always 0x800703f1.

Does anyone know a solution of this problem?

 

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

 

Lumia 540 upgrade is showing an error code 0x800703f1

Finally, resolved the error code "0x800703f1" and installed Windows 10 in my new branded Lumia 540.

After a lot of searching for this error code, got an idea that error code is related to a registry entry which blocks the upgrade. Referred link: How to fix update Error Code 0x800703f1 on Windows 10?

Suggested solution was to format and install windows 10.

Searching for the answer "How to format Windows mobile" I got a solution that using "Windows Phone Recovery Tool" we can reset and reinstall the OS again in mobile.

So, downloaded "Windows Phone Recovery Tool" from the link: Download Windows Phone Recovery Tool by Microsoft

Install "Windows Phone Recovery Tool" in your machine and connect windows phone to the machine. Recovery tool will automatically identifies the mobile model and starts downloading the OS. (1.66 GB file will be downloaded). Once the download completes, the
tool will ask for confirmation and install the OS to mobile. Believe it will be a fresh install (not equivalent to Hard / Soft Reset). Post that it will show the setup steps to start with the OS. Now the OS is reinstalled.

Now follow the steps in the link that explains Windows 10 upgrade using "Upgrade Advisor" app (Update your older Windows Phone to Windows 10 Mobile)

The above solution worked for me and upgraded my Lumia 540 to Windows 10.

Hope this might work for others.

Windows 10 is awesome.
