Same for us, we have an 890 model and have done a factory reset, didn't work, unplugged, didn't work. For use it happened between 8 and 8.39pm last night - I recorded Corrie fine at 7.30-8pm then noticed at 8.39pm that it wasn't recoding the second episode of the night. Tragedy. Left it plugged in overnight, came down this morning to find it was stuck in 'update'. We are near Solihull so it seems to be happening all over the country.
