It’s a bit of a pig but the top and back come off as one, but if you’ve got audio 3.5mm socket in storage compartment pop that out and there’s enough on the cable to unclip old usb socket and replace with new one. I’ve tried getting mine to work, but I’ve not succeeded yet!! Let me know how you get on, if your still having problems, I’ll send you a picture or two of how it all comes apart.
