I just killed mine. And it was all my fault. I had the v2.5 rattle board issue, from dropping it multiple times through out its lifespan. As a bandaid, I wedged a small piece of cardboard up there to keep the board from rattling. I dropped it this morning and dislodged the cardboard. Reaching up in there with needle nose pliers to re adjust the cardboard I ripped the button out on accident, and apparently ripped one of the wires coverings out. after that point I proceeded to pop off the top cap to see if I could re soldier the wire. I can, but at this point, with the button being ripped out, its going back to provape for some much needed love.
