My Dongle worked for almost 2 years I guess and I left it plugged in at all time for the last 8 months. Well it suddenly stopped connecting to my phone.

I work for an electronics manufacturer, and I figured I had nothing to lose by taking it apart. What I found were typical chinese solder joints. Dull gray, fluxy, and mis-shapen.

I decided to run the board through the reflow oven to reflow all of the solder joints.

I reassembled the unit, and now it works again.
