If you have only done this what you have described then i would say, yes, send it back.
Because only a factory reset should not bring your phone in this state.
Have you tried to press and hold the power button for 20 seconds?
Then it should be forced to switch off.
Sure......you have the option to fiddle around yourself.
In that case see the thread Restore Stock Firmware
if above mentioned does not resolve your stuck system
