Upgrading jetpack onto nvme without having to wipe out the system

Thanks again

The one and only time I managed using ota with xavier nx I did the following:-

I have never sucessfully executed OTA without errors and nobody hs managed to give me answers. Documentation is fine if it provides answers but mostly it does not.

Nobody has explained to me why upgrading using sdk manager with the operting system up and running orn the orin agx sdk manager does not connect

Re documentation —resources Jestson Linux 35.4.1. Release Notes

PAGE NOT Found.
All I’m asking for is a system for upgrading that works which over the last couple of years I have not found a solution.

I AM NOW GOING TO UPGRADE MY JETSON XAVIER NX FROM 5.1.1 TO 5.1.2 AND LET YOU KNOW ALL THE PROBLEMS I COME UP AGAINST.
THE NX IS A DEV KIT WITH NVME WITH NO eMMc

I have now tried to upgrade xavier nx which got to the end having answered yes to 3 questions. The process got to end to which I rebooted.

It now keeps saying
A:
nvidia-l4t-bootloader Post Install Notification
reboot is required to complete the installation.

When I do the grub the menu says updating … until it gets to 11% then re-starts thus arriving at the Desktop.
GOTO A:

dpkg-query --show nvidia-l4t-core
nvidia-l4t-core 35.4.1-20230801124926
Where do I go from Here as this is another different outcome trying to updagrade?

Sorry to be a pain but your systems seem to be far from perfect.
Cheers
