A Fitbit Luxe whose update will not finish, is stuck at a percentage or fails with a message has an interrupted transfer to repair, and the cause is almost always the battery, the connection or the phone. The Luxe is Fitbit's slim, jewelry-style fitness tracker, with a small color AMOLED touchscreen, heart rate, activity and sleep tracking and no built-in GPS, ECG, microphone or speaker. It updates through the Fitbit app over Bluetooth, and the update is a download to the phone and then a transfer to the tracker, which takes several minutes and needs a steady link.
The checks in more detail
Check the basics. The tracker needs enough battery for an update, usually at least 50 percent, and the update fails if it runs low, so put it on its charger and leave it there. Keep the phone and the tracker close together, with the Fitbit app open and the screen on, and do not switch apps or lock the phone during the update. Make sure Bluetooth is on, the app is up to date and the phone has a good internet connection, since the download uses it.
A phone in battery saver mode or with background activity restricted can interrupt the transfer; turn those off for the update. If the update is stuck, restart the tracker using the method in Fitbit's guide for the Luxe, which uses the button on the charging cable, then restart the app and try again. Sync the tracker first, then check for the update again. Turn Bluetooth off and on and forget the Luxe in the phone's Bluetooth settings if it has a stale entry, then reconnect in the app.
Try a different phone or the Fitbit app on a tablet to see whether the problem is the phone. If the update still fails, remove the Luxe from your account in the app and set it up again, which often completes the update as part of setup. Note that a Luxe that has never been updated may have a long update to install in several steps, and that is normal. Contact Fitbit with the serial number if the update still fails.
