I'm using the HTC Sync Manager to upgrade the device.  It downloaded the software, then reboots to install it and gets stuck at 12%.  The phone just displays the HTC logo in black and white.

I'm the 2nd owner of this device but I'm on Pageplus.  If I bring the device to a Verizon store, will they help me upgrade it?
