Yes, I've tried pulling the battery multiple times. Hard reset won't work either. I've tried volume down + power button, both volume buttons + power, even the camera button + power, charging with the computer, using different USB cords, and it still won't turn on. I took the battery and SD card out, waited 30 minutes.. put it back in, no luck.
Could it be a battery problem? Will a new battery fix it? Is it a hardware problem? If I need to replace it, could the Sprint store still retrieve my text messages and contacts? I hate not having a working phone and Christmas is coming up.
