Einleitung

The SD/SIM card board houses the SD and SIM cards, and connects them to main circuitry of the phone.

Pry the back cover off of the phone with your fingernail. There is a notch located at the bottom of the phone for improved leverage.

The battery is the large black rectangle towards the bottom half of the phone.
There is a semi-circular notch at the bottom edge of the battery. Press against and up on the battery to pop it out.

Remove 9 screws from the phone. The locations of these screws are circled in the picture.
5.5mm length PH00 screws
4mm length PH00 screws

Using a plastic opening tool, gently pry around the perimeter of the device.
The ribbons behind the buttons and ports are very delicate. Make sure you do not run your plastic opening tool too deep into the bezel, as you could damage them.
The button covers rest under the Mid-Cover Bezel. Remove them and set aside.

I think they want you to refer to the blue tool as the "plastic opening tool."

Using a spudger or plastic opening tool, gently disconnect the ribbon cable attached to the black SIM card board.

Use a hair-dryer on high, or a heat-gun on low to heat the device and loosen the adhesive which holds down the SD/SIM Card Board.
Evenly heat the device in short intervals for about one minute.
Do not heat the device for more than 30 seconds at a time to prevent over-heating.

You could also use the iOpener tool for this step. What is that the adhesive is holding in place?

Gently pry the board up to release it from the now soft adhesive. Make sure you pry up the little tab connected to the camera unit as well.
If the board is too difficult to separate than more heating may be required.

Abschluss

To reassemble your device, follow these instructions in reverse order.
