New Humax Aura during installed tried to update from version 6 to version 7

But display shows Remote control update at 99% and hangs (repeatedly).

If OK key is pressed, it retries from 0% taking about 50 seconds, but ends hung at 99%.

How do I find if the update has actually succeeded? And where are release notes for updates?

And does this indcate a fault?

I believe that it is using IR mode (button flashes red).

Remote control appears to work OK.
