Removing this and attempting to reconnect the connector ribbon will be really difficult when re-assembling. If you are simply replacing the LCD screen I recommend skipping to Step 13.
Thanks for this! I will just add that there is no need to take off the image sensor and the microSD board. You can simply skip from Step 6 to Step 13 without removing the motherboard. I wasted a lot of effort and almost broke my GoPro doing Steps 6-13.
