Overview
Step-by-step
- 1
Power down the device
1 minPress and hold the top button and either volume button, then slide to power off. Ensure the screen is completely dark before continuing.
- 2
Heat the screen perimeter
3 minUse a heat gun on low heat setting to warm the outer glass edges for 2-3 minutes. Move the heat constantly to soften the display adhesive without damaging the LCD.
- 3
Attach the suction cup
2 minPlace a suction cup near the bottom edge of the glass display screen. Pull upward firmly to create a tiny gap between the display glass and the frame.
- 4
Insert an opening pick
2 minSlide a thin plastic guitar pick into the gap created by the suction cup. Keep the pick inserted no deeper than 3 mm to avoid slicing internal ribbon cables.
- 5
Slice the display adhesive
5 minSlide opening picks around the entire outer perimeter of the display. Reapply heat if the adhesive becomes tough to slice through.
- 6
Pivot open the display
2 minGently lift the right edge of the screen and open it sideways like a book. Prop the display against a solid box so it does not strain the connected ribbon cables.
- 7
Unscrew the battery shield bracket
2 minRemove the screws securing the metal plate over the main battery connection. Lift the metal bracket away using precision tweezers.
- 8
Disconnect the battery power
2 minSlide a plastic blocking pick beneath the battery contact pad to isolate power. Leave this pick in place to prevent short circuits during solder work.
- 9
Remove the display connector bracket
2 minUnscrew the metal shield plate covering the display and digitizer flex cable connectors. Store the removed screws in an organized layout tray.
- 10
Disconnect the display cables
2 minPry the display and digitizer connectors straight up from their motherboard sockets using a plastic spudger. Do not pry against the surrounding surface components.
- 11
Separate the display assembly
1 minLift the display assembly free from the frame and place it screen-side down on a microfiber cloth. Keep it in a safe area free of debris.
- 12
Unscrew the logic board shields
3 minUnbolt the retaining screws holding down the lower metal shield plates near the bottom of the logic board. Lift off the metal plates and set them aside.
- 13
Disconnect lower board cables
3 minPry up the speaker and antenna flex cables surrounding the USB-C port using the tip of a spudger. Move the cables clear of the work area.
- 14
Apply flux to charging port pads
2 minApply a small coating of flux over the solder joints securing the USB-C port to the logic board. Flux ensures uniform heat distribution and prevents solder bridges.
- 15
Desolder the damaged USB-C port
10 minLay desoldering braid over the port solder pads and apply heat with a soldering iron to draw up old solder. Gently lift the damaged port free once all pads melt.
- 16
Clean the motherboard pads
3 minDampen a cotton swab with 99% isopropyl alcohol and clean off burnt flux and residual solder from the pads. Ensure the contacts are shiny and flat.
- 17
Solder the replacement USB-C port
12 minAlign the new USB-C port carefully on the logic board pads and solder each pin firmly into place. Use a magnifying glass to confirm there are no solder bridges between pins.
- 18
Reconnect internal board flexes
4 minSnap the lower speaker and antenna flex cables back onto their board connectors. Replace the lower logic board shield plates and tighten their screws.
- 19
Attach display connectors and shields
3 minPress the display flex connectors into their motherboard sockets until they click. Secure the display flex shield plate with its original screws.
- 20
Remove battery isolation and seal display
5 minRemove the plastic pick from under the battery contact, reinstall its metal bracket, and lay down fresh screen adhesive before pressing the display flush.
