The front speaker grille pries off with a metal spudger (am I spelling that right?). The Torx heads are where the six posts slide into the front plate / speaker mount. They are style only and don’t unscrew.
Remove the ten screws; six across the top, four across the bottom. Two arrows show where to insert your spudger to pry the speaker plate out. Boom! You’re in!
On mine, the back of the micro USB input had come out and the jack’s tab to hold it weakened. I unplugged and removed the speakers, battery pack, & back port assembly. The assembly has two screws and needed some force with the spudger to loosen the adhesive holding it in. But it came apart with no damage.
I put all back in place and applied a blob of hot glue to the back of the micro USB jack to hold it together.
It all went back together just as easy and works fine now.
Cheers
