My nokia 206 doesnt switch on after factory reset.

I recently factory resetted my nokia 206 using security code... ever since, while trying to switch it on, the start up word nokia comes up for a few seconds and the phone never turns on. Ive tried to switch it on without any sim cards or memory cards yet it doesnt help... i tried the hard factory reset method *+power button+call button+3 and yet it doesnt work. Can anyone please help me?
