Good Day Guys! My borrowed JBL PULSE 4 works fine, adding the use of JBL Portable app to customize lightings etc. But I had a problem after the software update of the JBL Pulse 4 using the app, after the update was completed, the speaker won't turn on anymore, neither is charging, it doesn't respond to anything, completely nothing works. The app JBL Portable, broke my borrowed speaker because of the software update it showed on the app. Please help, is there any ways? 😭😭😭
