my son has a droid x, and when he turned it on the other day, it showed a triangle on the screen with an exclamation point and the little droid guy. Then he messed with it, and it worked for a day. This morning, it showed the same thing. We took it to the verizon store and the manager said they didn't know what was wrong with it. she gave him a new battery and did a system reboot and wiped all the data, and it still is stuck on the screen with the picture of the warning triangle and the droid guy. PLEASE HELP!!! thanks!
