Heat up the glass for 3-5 minutes. I chose to do it for 4 minutes.
You only need to use your heatgun on the lowest setting. I wouldn't recommend using a hair drier as it doesn't get very hot.
You must be careful when using the heat gun on this device. If the device is heated up too much then it may melt the digitizer and cause discoloration. If you start to see any discoloration then shut off the gun immediately.
This procedure softens the adhesive that holds the glass to the screen assembly.
I never got any photos, but when taking the glass off be very careful near the two touch keys at the bottom of the phone as it can be easy to damage them. They are stuck to the glass and need to be taken off before lifting off the glass.
With the glass removed, you'll end up like your phone looking like this, with the adhesive residue leftover on the digitizer.
Clean up the digitizer with lint free wipes or a clean microfiber towel. I used some lens cleaner on a microfiber cloth to clean mine up.
I probably did a terrible job of removing the glass and the digitizer appears scratched. If yours does look like this as well it's no problem, when the screen is turned on it's not noticeable.
