With the help of a fine opening tool we are unhooking the back shell. We have used a metallic tool, but it would also be worth a plastic as a spike for example.

We disconnected the battery, and pulled the stickers that are on the battery. You have to pull the stickers carefully as there is a possibility that the sticker will break.

Remove the 4 Torx screws (T4) and remove the antenna module and speaker.

We disconnected the interconnection flex from both ends and took it off the telephone chassis.
