iPhone 17 Pro Max USB-C Installation

Carefully inspect your replacement USB-C port assembly and remove any adhesive liners.

Align the assembly with the bottom edge of the frame and place it loosely in place.

Use a JIS 00 screwdriver to install the two 2.8 mm‑long USB-C port screws to the bottom edge of the frame.

Make sure to install these screws in the holes marked in green, not red.

Install the nine USB-C port assembly screws:

Six 1.5 mm‑long JIS 00 screws

One 1.3 mm‑long JIS 00 screw

Two 1.2 mm‑long Y000 screws

Use a JIS 00 screwdriver to install the 1.2 mm‑long USB-C port assembly screw to the bottom left corner of the frame.

Use a JIS 00 screwdriver to install the 1.2 mm‑long USB-C port assembly screw to the right edge of the frame.

Use a spudger or your finger to press the buffer strip back onto the frame. It should cover the screw you just installed.

Use tweezers to remove the adhesive from where the microphone attaches to the frame.

Use your finger to align and press the microphone module onto the frame.

Use a hair dryer or an iOpener to heat the entire USB-C port assembly until it's warm to the touch. This helps the adhesive to bond better.

Use your finger to press and connect the two press connectors to the logic board.

Place the left logic board buffer in its recess.

Use a JIS 00 screwdriver to install the two 1.8 mm‑long left logic buffer screws.

Inspect the existing battery buffer adhesives on the frame. If they're still tacky and not deformed, you can reuse them.

To replace the adhesives:

Use a spudger and tweezers to remove the adhesives. Be careful not to scrape the delicate graphite sheet.

Replace the adhesives with some double-sided tape.

Use your fingers to lay the battery buffer in place.

Press down on the buffer for a few seconds to secure it.

Use a hair dryer or an iOpener to heat the battery buffer until it's warm to the touch. This helps improve the adhesive bond.
