I need to kno how to open my speaker to fix the charging port!
So I opened up my Sharkk because it had water damage, so I was pretty cavalier about it. But it’s actually not that hard if you know how! Remove the back metal grating. This isn’t hard, just use some tweezers and pry it out. Then you’ll have access to six screws. Remove the screws, then the back underpanel comes out. You’ll then have access to the motherboard, the (very rusty, in my case) battery etc. The USB port is right there on the motherboard. I found the OEM website, it has a nice accurate diagram: http://www.hi-fid.com/product/50885070.h… The Sharkk is just a spin on this HFD-869TWS.
