Model 9 has a separate LCD display and digitizer.

when selecting a replacement digitizer, check that there is an adhesive applied. If not, one extra sheet will be needed.

because of the finely broken glass, be sure to wear safety glasses (you only have one pair of eyes and they cannot be replaced). Think about protective gloves if you need to.

Additionally: cosmetic sticks and some isopropanol (100ml is enough), tweezers (pincetce), a PH00 star screwdriver, a piece of thin plastic to disconnect the battery pins and a soft guitar pick - it will be perfect.

Small plastic blade will come in handy. The piece of plastic I wrote about above must be really thin but quite stiff. You can use a piece of neatly cut paper from a school notebook (non-conductive).
