Since a few months my tablet is stuck with the 'password changed, wait....' message. I had hoped that I could overcome this with the steps mentioned here. But unfortunately not
I can't start it anymore, so I'm not sure if it is in developers mode or not. Also, plugging the device in my mac didn't let it download the drivers.
Too bad, because when it was working it was a great tablet, now it's just a expensive drawer filler
