I think people should be made aware that if you want or need to update the firmware, you are required to agree to Bose's Privacy Policy in order to download the updater app, and I don't think those policies really align with the spirit of "right to repair." Just as an example, by downloading that software (that you need to update the firmware) you grant Bose the right to collect information about "content accessed via your product or software (e.g., sleep tracks, stations, playlists, artists, albums, songs, or podcasts)." (I am a lawyer, but I am NOT your lawyer, and your facts and circumstances may vary from mine, so don't take this as legal advice and there is no attorney-client relationship between us.)

I would only add one additional part (and half of a step). Get so,e Threadlock Blue 242 and apply a little bit to the threads of the screws when re-placing the back case. If you open the back up a lot, this helps keep the screws from coming undone and falling out (for years before I figured this out I used to have patches of gaffer's tape on the bottom side of my computer).
