JBL Flip 2 Bluetooth Speaker Complete Teardown, Diagnosis, and Rebuild

My friend John moved back to South Africa last year, and he sorta “bequeathed” me his old JBL Flip 2 Bluetooth speaker. It’s got great sound, but a slight problem when charging: the USB port is extremely loose, and you have to wrap the cord around the speaker in a jury-rigged fashion to keep it held in place. After a few weeks, I finally decided to take the thing apart and see if I could fix it.

After a little exploratory surgery, I found that the source of the problem was that the USB connector had essentially come unsoldered from the PCB it was attached to. A little bit of solder and the prodigious use of E6000 later, the JBL Flip 2 Bluetooth speaker is back to operating like new!
