I had the same thing happen. I took it to a Sprint Repair store, and after 2 hours they said Yes the charger port is bad. They replaced it, but told me if I brought it in again with a Custom Rom that they would not service it again. So it's risky. If you can get a hold of a charged battery, or buy one of those charging docks, then download or bluetooth a stock .nbh as stated before and flash it using bootloader!
