Reconnect the battery connector and secure it with its bracket and screws. This will power up the device once it is reassembled.

Gently press the screen back into its frame. Use adhesive strips designed for the iPhone 14 Pro Max to ensure a secure fit. Apply pressure evenly along the edges to ensure the adhesive bonds properly.
