mobile

I was trying to flash recovery and it was done seccessful but when the phone was sent to reboot it didn't turn on again, no logo appear, it is completely dead, but if I connect the phone to PC it recognize the phone as "qualcomm hs usb qdloader 9008"...
Can you help me to fix my phone please? I found some files to restore other phones but I can't find a one for Samsung Exhibit 4G... please!!! :D
