Hi PinkiPad. I got this explanation from the net, (there may be others) but it said this:- "The white triangle with the orange exclamation point indicates that you are at the boot screen. You can try pushing both volume keys at the same time (if you have Android 2.3) or you can try pushing the volume up and power button. One of those should bring you to a menu. Use the volume key to select reboot system now. If that doesn`t work do the same things but select factory reset/data wipe. You will lose all data, but the device may start working again. If it does not, you probably have a hardware problem." You probably just had a temporary error and the reset fixed it. Hope that helps. Good luck!
