I have a Samsung Galaxy S1 Fascinate.
It's frozen at the recovery screen. I tried to reboot my phone (pressing power + vol up + vol down buttons at the same time), but the screen is still stuck. It has the picture with the little green Android standing there with an opened box next to him (an arrow is coming out of the opened box).
There are no other options on the screen. I've tried pressing other buttons and even pulling the battery out. But everytime I turn my phone on, it just goes back to the screen with the little green Android and the opened box on it.
