My Iconia A1 froze completely. I did a complete factory re-set, which I've done before with no problem. This time, the tablet just kept going thru the factory re-set and giving me the screen to select the various options of "Reboot, Fast reboot, etc.". I couldn't even get it to shut down. Now, when I push the power button, it makes the short "buzz" sound it would make when being turned on, but nothing else. Can anyone give me any options as to how to get it to function again? Thank you very much!!
