Firmware update not working with iPhone [FIXED]

Hello! Perhaps this can help someone else avoid a bit of frustration.

I struggled with applying the update using my iPhone. After swapping out cables, adapters, testing the lightning to 1/8 in. adapter, etc., I finally realized that Settings > Sounds & Haptics > Headphone Safety > “Reduce Loud Sounds” needed to be turned off.

It appears that the send volume was not loud enough with this setting enabled and the symptom that I was experiencing when the update wasn’t working was: LED lights would glow / pulse, ready to receive data, but wouldn’t change status after 6 seconds.

Hi there,

Sorry you ran into this and thanks so much for sharing on the forum. I’ll pin a comment at the top of the firmware update video with these findings.
