Why do all top panel LEDs flash when switched on? Why can the product not be connected or does not function?
The top panel LEDs are flashing because the OTA firmware update is in progress, the product should work after the upgrade is completed. It may have been caused by a previous interruption to an update.
It should be possible to resolve the issue by doing the following:
- Plug in the power cable and wait for at least 5 minutes for the Partybox Ultimate to complete the update.
- If the Partybox Ultimate stops flashing, but cannot power on, then perform a factory reset by pressing the two buttons below for more than 10 seconds: Moment (heart symbol) and Play (or through the JBL One app). After this has been done, press the Power button.
