I thought my unit was toast. Touch Calibration was off, could not enter password. Copied the files on 16 gb thumb drive and inserted in #1 USB. Booted up to Password Screen and in a couple of seconds, the option screen came up and scrolled to factory reset. After reset, cycled power off then on. Asked if I wanted to set password and I declines. After this, I reformatted thumb drive and unzipped latest firmware onto it. Updated the firmware and everything is operating correctly. A Big Thank You t
