Antwort auf „My JBL Flip 4 doesn't turn on and charge.”Hi guys I had the same problem. To reduce the bass I tried to push some buttons together and the device shut off. I could not turn it on again, just charging but with no chances to turn it off and on again while charging. SO I tried many combinations and the one that worked for me is: while is charging be sure the led is blinking and the power button led is on. If that is the case holding the triangle/play button and the bluetooth button together should turn it off and since then let you turn it on again. To set the bluetooth on your paired device just push the bluetooth button on the device again and then connect it through your paired device, for me it works.
