If it is in warranty contact Samsung or your carrier support. Some people have had success with that error after flashing a new ROM to it. Just do a web search for this error and you will see some things about it. I am guessing if you could not do this yourself in the first place, you may not be able to go through the ROM flash instructions, which means bring it to a repair shop or work with warranty repair if you can.
