I was just wondering if anyone would know of a resolution to an issue I am having. I recently purchased a Nokia Lumia 2520 AT&T branded unlocked from a popular online vendor. I plugged the tablet into the wall to charge for the first time with the Nokia proprietary wall charger that the device came with, and a black screen with the name "Nokia" appeared in the center of the screen. I left it connected to the wall charger for four hours and the name "Nokia" is still there. It hasn't booted to the start screen for the first time yet. No other information has shown on the screen. I tried to turn the tablet off and the "Nokia" name stayed frozen there on the screen. I pressed and held the on/off switch for 10 seconds and the tablet turned off. When it turned back on, the name "Nokia" was still there....frozen. Any suggestions as to how I might be able to boot to the start screen for the first time? Thanks.
