It's fairly easy, once it's out you would remove both brackets from either side. Then fours screws holding the top half of the grey fascia on. Then you separate the screen unit from the fascia it's held also by a cable on the top right. Four screws hold the screen casing at the desired angle... when removing from this bit be careful it's half by a cable and really short ribbon cable be careful not to damage it.
Lastly four more screws open the screen casing. To separate the screen from the old digitalizer I used a hairdryer to heat the bonding and a crafting knife. They do smash easy so beware, then bought some double side stick pads and attached the new ribbon cable. Just reverse to put together.
