Phone won't turn on

My zte n290 phone wont turn on. As the power button is pressed the loading bar comes up(loads up by % 1-100) and then the phone turns off.I think it had to do with the Uart 2 settings in the engineer menu when it was set to uart 2.

Can you 'reset the device'?

No I cant, or I don't know how to do it while the phone is turned off.
