TIP FOR HOME BUTTON REMOVAL
I found it to be simpler by using the same pry tool shown in the image and pry the tab furthest from the flex cable. Its an easy start knowing that if you damage the cable you can loose Touch ID permanently.
My steps were basically as follows in this specific order:
1. Using a guitar pick, release the cable from the adhesive and SLOWLY lift up the cable and the components with it
2. Once you reach the tabs that hold the home button in place, pry the tab furthest from the flex cable (this requires a little more force)
3. Once the tab furthest from the home button is lifted away, you can hold on to the metal piece (The whole tab) and lift it away safely.
4. Using your finger, press in the home button to release it from the glass and your done.
