you could try but I'm am sorry to say it but, as other said you have an expensive brick, What where you thinking when you did that? Do you have any notions about flashing phone or GDFS, EROM OTP and so on? GDFS is unique to each phone, I guess you didn't know that, the best thing to do is take it to a service center, if it's under warranty say that you can't turn it on, if it's not under waranty be prepeared to pay, or you could buy yourself a new phone and use this as a display model. Good luck!
PS: you got your GDFS backed up before loading the other GDFS from that site or you backed up after you loaded the GDFS? if you did it before you might have a chance if you did it after you might have half a chance at a professional.
