Android System Recovery

By powering off your device and then pressing simultaneously the Volume Up key + Home key + Power key, we can boot into "Android System Recovery" screen. Volume key allows you to select among the options on the screen, however, if the screen just stuck at one area, first check if buttons, especially the volume button is ok. Just press the key and release for several times, you can figure it out.

Sometimes, the permanent system unresponsiveness would cause the problem. Press the power button to turn off the phone, take out the battery, after a while put the battery back and power it on again. See if it works eventually.

Press the volume button and select "wipe data/factory reset" option. It's the last attempt to fix the stuck and freezing problem here. And this solution is said to be the most helpful, however, it's kind of risky. We know that factory restore your device will remove all data on it. Will you afford the risk?
