Just saw this now....
I assume you've resolved the issue??
If not, what else have you tried?
If so, were you able to identify the cause?
And to answer your implied question, plugging-in the USB for power will adversely affect the update, it can only make it safer and faster.
Thank you very much for your interest.
Unfortunately, I was not able to solve it.
I kept it another three hours as it were (with 22% success). Then I tried a reset which did not work. Finally, I opened the calculator, took the battery out, and back after a short time. There were little dots on the screen. I took the battery out for a longer period (30 minutes) and took it back. Now it was dead and I was unable to wake it up again.
When I opened it I saw a strange white liquid (see photo). I am absolutely sure that this was not brought in by me. Can this be the reason?
