Phone Problem after update Alcatel OT 6012

Hello ,
I have the following issue:
Today I recieved a message that i have firmware update . Downloaded it and it started installing. Everything was going well untill the instalation was complete , then the phone restarted and loaded only on the white start screen with "ALCATEL ONE TOUCH" and "SMART MOVE." , and that's it. It cannot be turned off (when i push the power button it only restarts) What can I do ?
