I've been trying for months, (it might be up to a year now) to revive my TP. I tried leaving it on a charger, plugging, unplugging, button presses of every conceivable combination. In all this time the only sign of life was the home button blink exactly once.
I jotted down your instructions, along with another from another thread. I had very little hope this would work. I tired your's first because it was simpler. It took several attempts, but I got the home button blinking left-right! It's charging right now and I think I might be able to revive it! From what I read here, it should be charging when the home button is blinking in this fashion.
I thought I'd killed the golden goose. The first time I got it blinking, I waited a few minutes, then decided to see if it work on the Touchstone. It didn't work (I didn't try too hard) and it took a few tries to get going again on the USB charger. Whew! If you can't get it to work the first time, keep trying. I don't know if it makes a difference, but the two time I got it to work, I released the Vol+ button about one second after plugging the charger into the TP. It did not work if I released the button quicker or slower. To be fair, it didn't work several times releasing it after one second.
The other instructions I didn't try: plug the charger into the wall without a cable. Then connect the TP to a powered USB port on a computer with the HP cable and let it sit a short while. Then move the USB end of the cable from the computer to the plugged-in wall charger as quickly as possible.
I'll report back with an update....
Thanks so much!
Update: At 10:35, after about 6 hrs of charging with a left-right blinking home button, the big battery icon showed. Some hours later, I noticed the home button was blinking two pulses. I hit the power button and opened to the lock screen! Yeah! Back in business! Thanks so much!
