Take the following steps:
- Power off all LIFX bulbs
- Turn on a single bulb
- Run the updater again
If the bulb updates, repeat the process one bulb at a time.
If you experience issues using the iOS LIFX Updater app, or in app Android updater, please try one of the desktop updaters available here.
If the bulb is still having issues updating, please copy the log in the updater, and contact support with the log, so we can assist further.
