Perhaps a different battery would do the trick, you list that you have tried a hard reset, correct?
I believe so, according to the instructions I've read in other forums. I've held down the volume up and power buttons. A screen came up and told me that the OS would come up in 10 seconds if I didn't make a choice. Well, 3 minutes later, nothing came up. So, I selected the little Android thing and pressed power. It started to boot up, but then continued to do the same thing. It powers on, stays on the "Toshiba Innovations" "home page" for a few seconds (normally, after this, the second screen would appear to show it's booting up. But, after a few seconds, it automatically powers down and resets back to that initial TI screen. Then, shuts down, and comes back on - it's a cycle that doesn't stop.
It does the same exact thing when it's plugged in, too, so the battery may not be the problem (to my very limited understanding of how things work) :-)...
From that screen, you need to make a choice, which is wipe/factory data reset. You should highlight this with the volume keys then select it with the power key
Ok, not a problem - I would be happy with factory reset.
Which of the three icons will do that? I've tried all three that appear. The first one looks like the USB symbol, which did nothing when I selected it. The second is a file folder symbol (which also did nothing when I selected it) and the third is the Android symbol, which, as you guessed, I'm sure - did nothing when I selected it.
Is there another way?
This is the cure all for anything related to the device. Your next step is to proceed with your warranty coverage either through Toshiba or through the store you purchased it from. If it was Best Buy check out their black tie protection plan
