latest version of remote firmware?

[Ty S]

I got my inspire last monday and immediately updated the firmware on both the UAV and remote. The craft had the lasted firmware according to the Pilot app and didn't update, the remote however went through the process if should have. I just got my 2nd remote today and went to update the firmware, nothing happened however. I hooked it up to the Pilot app and the firmware says 1.04 on my new remote. as a safety precaution I checked my original remote that had been updated and it says version 1.03. How can I get the 1.04 firmware on the old remote since I have the latest firmware downloaded from the DJI site?
