Had the dumb thing on for over an hour, decided to turn it off and on, worked like charm. Redownload and update was done in 12 mins. Made 2 CC calls and both gave me the same answer '3 hours needed for update'. I mean wt*? Imagine if you had to stare at the black update screen for 3 hours. As someone who already had one stb f'ed up by an update 2-3 years ago(and the technician convinced my mom to buy a new stb with adp), I had to wait long enough to be sure, before I do the common 'turn it off and on'.
Thanks guys for your replies.
Tl;dr If updates' stuck better turn the stb off and then on. Its a risk though.Update takes about 12mins in total.
