Try booting back into download mode (power device on from an off state using power+home+vol-down) and reflashing the stock MJ4 tar file. Hopefully it will reboot into stock MJ4. Then boot into stock recovery (power on device from an off state using power+home+vol-up) and wipe cache and do a factory reset. Then reboot back into download mode and reflash the stock MJ4 once again.
From that point you should be able to take an OTA update.
Note: when flashing a ROM via Odin.. Wait for Odin to show you how long it took to complete. Your phone may reboot. Pulling the plug early may result in errors.
