So the repair guide is great. However you should not buy the camera from ifixit. You need to go to https://selfservicerepair.com/ and buy the camera there. You can get all the tools and anything you need from ifixit but you need to order the part from the apple selfservicerepair and enter your serial number. Then follow this guide and contact them through your order details to initiate the calibration. The process requires you to contact the service rep and have them connect to your phone and lead you through the calibration. Worked like a charm and wasn't that hard of a repair. Thanks ifixit for all of the info!
