After the 11 screws are loosened use the plastic opening tool and gently pry the protective plate from the back of the device. Once the plate is off, use the same tool to gently remove the 3 ribbon cables located directly above the battery. On the left side of the battery on the phone case, there is a groove where the plastic opening tool can be inserted to pry the battery up and out.

To finish removing the headphone jack the screw in the purple circle fastening the headphone jack to the motherboard will need to be removed. Once slackened, the headphone jack can be pried up using the plastic opening tool, as seen in the picture.

The battery cover of my mx3 had 9 screws visibles. The last 2, the top and bottom middle screws, were hidden under a layer of paint and didn't look like screws. Just push the screw driver in and break the paint layer. I would guess that this is the equivalent of a warranty seal, so if your phone is still under warranty think carefully before you do them.
