I had heard that it was a good idea to discharge new phone batteries and recharge them from zero.... unfortunately mine would not come back on after trying to charge it back up. I used the supplied charger and other micro usb chargers, just in case it was a faulty charger(unlikely). The boot up of the phone stops at the AT&T splash screen logo after the NOKIA logo and will not proceed any farther. A real bummer. I've tried all the soft and hard resets... nothing has worked. I will most likely have to exchange for a new one tomorrow.... the day after the "Launch Day" today... Easter Sunday, as most every AT&T store is closed. Auspicious start. Anyone else possibly brick their new phone? Any other advice to try?
