JBL Flip 5 Service Mode

When the JBL Flip 5 is in service mode, the buttons do not work. So, assuming that all the systems are okay, we’ cover how to end service mode, and restore proper function.

JBL Flip 5 Service Mode: May Be Active

First, when in this (often called ‘weird’ or ‘secret’) mode, the Flip 5 does not power ON without the charger. Thus, it will not run on the internal battery while in Service Mode.  Furthermore, when you do apply outside power, it powers up without you even pressing the Power button.  So it comes ON as soon as you connect the charger.

Further, you cannot turn off the Flip 5 while in this mode. Not without the charger. And then, when you disconnect the charger, the speaker powers off without pressing the Power button.  So when this Service Mode is active, the Power button appears to not work.





Indeed, none of the buttons seem to work, except for the ones you need to exit Service Mode.  E.g. The Flip 5 won’t pair with any devices.

How to Turn On Service Mode

This is what you may have done by accident prior to your speaker freezing… To turn on this mode, power up the Flip 5 first. Then press the Bluetooth and Play-Pause buttons together. Hold them in until the speaker powers OFF. So this usually takes ten seconds or so.

Note that you can enter this mode whenever the Flip 5 is ON. It doesn’t matter whether the charger is present or not. You can also enter it whether the Flip 5 is running on batteries or external power.

JBL Flip 5 Service Mode: How to Exit It

Now you can restore proper operation by deactivating this mode. But note that when Service Mode is ON, then you must connect the charger to turn it OFF. Why?  Because the JBL Flip 5 won’t come on without outside power. Yet you can’t change modes without powering it up first.  So, you need a USB-C power adapter to make this fix.

    1. So, connect your speaker to external power. Next, the speaker comes on.
    2. Then, with the speaker Power button glowing, press the Bluetooth and Play-Pause button combo. Then hold for ten seconds or so, until the Flip 5 powers off.
    3. Finally, normal operation returns the next time you power it on. So Service Mode is over.

Finally, all buttons should now work again, whether or not you connect the AC adapter.
