Hello there. Ever since I got my Surface Pro 3 i7, whenever there is a firmware update, my SP3 gets stuck with a black screen with the message Please wait while we install a system update. The first time this happened I waited 3 hours and then I finally got fed up and used the power button and volume key trick to reboot. Today after the new August firmware the same thing. I've been waiting almost 2 hours now and I'm now going to use the power button and volume up key to reboot. Everything seems fine after I do this, but my question is.... Is there something wrong with my Surface? Why does this keep happening? How can I prevent this from happening again when ever the next firmware update comes out? Thanks!
