It didn't work for me. I never tried the factory reset though.
I also tried another thing: changing the date and time settings, restarting, and setting the date time to the correct date time again. I don't have these settings on automatic. Changing date and time didn't work either.
However, today the clock was set to summer time (this always happens automatic, even when the date/ time settings are not on automatic). Somehow this event triggered updates again
