If you have USB connectivity, you can use fastboot to flash a custom recovery, put a copy of the SuperSU.apk on the internal memory, then use that recovery to install SuperSU (or Superuser). That'll get you root access on the device, allowing you to use MobileODIN to flash a custom ROM if that's what you want.
