I got the router(dlink 2750u c1) from my telecom service provider(Etisalat,Dubai,UAE). Recently i have taken my router to India in order to setup with local ISP(BSNL,India). Unfortunetly i was fail to do, due to the limited options. So i thot to update with india dlink firmware and i did copy the updated firmare file to the modem and then restrated, from there onwards there is no indicator lights on the modem are off completely non-reponsive.
Is my router dead?...

Or is there any way to install the firmware to bring back my router?
