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.
I experienced the same problem after firmware update for my JBL charge 3. Has anyone figured how to fix this problem. My JBL charge does not not charge or turn on at this point.

Same thing happened to my JBL charge 3. Was working great, updated the software with the JBL connect app...update finished. Speaker never turned on after that. No lights showing when plugged in either:(
