I got to removing the “back” cover. Black cover perhaps? There seem to be silver tabs from the front silver facing that are defeating my attempts to remove the cover.
Thanks for the great guide. Apple definitely made this one more challenging than the 4 or 3!
I was quite surprised though to reach the end and find no help on actually installing the battery. It sure would be nice if you added a section at the end about installing the tape. And reminding people to remove the clear plastic wrapping from around the new battery if such exists. I know it did on my battery from iFixit. Again thanks for the great guide!
