I just tried applying the 07/18 update from an SD card, using the power + volume startup.Something apparently went wrong with my first attempt. Instead of the progress display, I got a graphic of an exclamation point in a triangle with the Android icon.I waited a few minutes, but nothing changed, so I rebooted and tried again. This time I got the progress bar display. It made it to about the 20% point, and then the Novel rebooted itself.Now... The Novel powers up, but when I press or tap the screen, nothing happens for a while, and then the Novel reboots itself.If I hold down the power slide, I get the power off popup, but when I press or tap the screen to power down, nothing happens, again followed by a reboot.Doing a hard reset just powers up into the same state.Ditto with doing an adb shell reboot from my laptop.So... I'm stuck with the power on. Leaving it alone blanks the screen, but it just comes back on when I hit the power slide.If I can't turn the power off, I can't try the upgrade again, so I've got a doorstop right now. No idea what will happen when the battery runs down. I wish I could just pop the battery out like I do when my Droid goes belly up.Anybody else had a similar problem? Any suggestions?If I can't beat this in the next hour or so, I'll have to take the poor thing back to Kohl's and try to get them to make a swap.
