I would highly recommend against upgrading the latest firmware. Everything appeared to be updating successfully until the reboot. After the device rebooted, the lower right notification area mentioned that there was another firmware upgrade available. I clicked on it and BAM, the prime froze. I tried shutting it down by holding the power button. The notification window popped up asking if I wanted to shut down, but I was unable to tab on anything on the screen. The only way out was to hit the reset button. Once I did that the device seemed to be resyarting, but then it totally bricked. Now the screen shows 3 gears with an exclamation point in the middle. I contacted Asus support and they said they are aware of the issue, and will call me back within 24 hours with additional info. This tells me that I'm not the only one. Anyone else have this problem or an idea how to fix?
