I’d say removing the screen is BS. I realized that I didn’t have to remove my screen cable as I was able to flip the screen vertically while I take the battery out. Removing the screen cables causes more problems- you may end up with white squares on the top of the screen which seem to expand over time. Also it is very easy to bend little metal legs on the socket when prying the connector.
Why do I need to take the battery out? I replaced battery a few weeks ago and it seemed no need to disconnect the screen as well.
They seem recommending taking out connections more than necessary. Anyone let me know why leaving the battery there would make a problem for replacing the screen.
