I did the update to version 1.10 of the firmware for the D4 like I have done every other firmware update. this time when it got to 5 bars during the update. the screen went black. I let it sit for 10-15 minutes waiting for it to finish so I could verify the update. nothing happened. I call tech support and they had me do a factory reset. but my screen never came back. any suggestions short of sending it back in.?
