UNABLE TO UPDATE WINDOWS FROM VER 1803 TO NEWER

[klithos]

On my SB2 I'm now stuck in an andless loop. Any attempt to update Windows it says "Failed, It is not possible to continue".
I tried a number of times and solutions.
Moreover, the system was formerly giving me the option to update to 1903 version, but now does not give it anymore, although informs me that my version (1803) is now obsolete and has to be updated. Any suggestion ?
I put herebelow the resume of actions performed:

- 200312 - UNINSTALLING MOST RECENT UPDATES
- unistalled KB4346084, KB4486153, KB4523203, KB4537479, KB4537795
- system did re-install all of them but KB4346084, adding the update 2020-02
- applied Windows Update Reset script

Sorry about all this trouble, @klithos .

I suggest one of these things:

- Full "Reset", including erasing all data.
- Wipe (clear) your Surface down to "factory", as if you had just sold it.

You've apparently tried everything else.
