JBL wont't turn on and takes no charge after failed to update firmware
So, I have this JBL Flip 4. I opened on the phone the Jbl app, and it showed to update from 3.2 to 4.0 firmware. I agreed, then it showed to plug the device into a charger. I didn’t agreed that, then I made a phone call. After that I plugged the JBL in and agreed the firmware update. So after that the app showed it can not update it. I restarted the app and cleared cache 2 times, and waiting for the firmware update pop-up, it didn’t showed up again, after that I factory reseted the JBL by pressing the shown buttons for 10 seconds. After that the JBL won’t turn on and even it was not able to charge up. I tried to plug it in PC USB too. Notice:I put the JBL on charger after making the phone call and it was charging during the reset. I don’t think this device can be fixed without opening it, but I rly don’t want to lose its waterproofness.
The battery is fine I think, it charged up to 3 LED out of 5, maybe something with the logic board. I tried all the button combinations and it doesn’t show anything.
The question is:
- Can I fix it by not dismantling it ?
# Can I fix it by dismantling it ? (The waterproofness is not a problem then anymore)
# How could I fix it, if I can or trow out the logic board
# Or can I find a reset button on the logic board ?
Thanks all of you guys and please ignore the why you did that answers/questions.
I just try to make sure if I can fix it or I need to throw it out. Yep, the warranty is expired half a year ago if you ask.
