<p>My NXT works fine other than that. I got it from a thrift store will so I don't know much about its history and I don't have a USB connector. I don't know what to do.  What should I try next?</p>

I advise that you reboot the brick and even the software itself if necessary. It's likely that the brick is defective. Try using WiFi or USB if that doesn't work.

You cannot update the NXT firmware over Bluetooth, you need a USB cable like the found on most printers.
