Steps:

  1. First switch off your phone and remove the SIM card tray.
  2. Unscrew the two Pentalobe P2 screws located at the bottom next to the device's USB C port.

  4. Avoid to lift only the display instead of the whole phone assembly as doing so may cause damage to the screen.
  5. Use an iSclack or a suction handle to separate the phone assembly from the rear panel.
  6. In case you can‘t manage to lift the phone assembly out of the rear panel you can insert the pointed end of a spudger in the headphone jack opening and press the phone assembly upwards until you create a gap between assembly and rear panel. Then use the spudger to lever the phone assembly out of the panel.
  7. Don't remove the rear panel completely yet. There is a cable connected to it! It is running from the finger print sensor to the display unit.

  11. Unscrew the two Phillips #00 screws that hold the metal plate in place.
  12. The plate, which is covering the battery connector, has two little hooks on each side. Use a tweezer to free them and unhinge the plate by carefully moving it upwards.

  13. Now you can unplug the battery connector and bend it aside.
  14. The EVA-L09 model has an NFC antenna adhered onto the battery.
  15. If you are just removing the battery to get to the display, you can leave the NFC on the battery.
  16. Mark its place on the battery with a felt pen for reassembly. Carefully peel it off and make sure not to rip or crease the antenna.
  17. For reassembly, place the NFC antenna on the battery where it was before so its contacts align with their counterparts.

  18. Free the ends of the adhesive pull tabs to get a good grip on them.
    19. Step image Step image
  19. The battery is secured with three pieces of adhesive, a removable pull-tab in the center, and on the SIM tray side. A third piece of adhesive on the button side has no pull-tab.
  20. Pull the adhesive tabs in a slow constant movement to free the battery.
  21. Should those adhesive tabs snap, you might want to use an iOpener to heat and soften them a little bit so you can pry out the battery with a spudger.
  22. There are two cables running directly underneath the battery. Take care not to damage them when prying with a spudger! You can see their position in the last picture.
  23. Slowly lift the battery toward the button side and free it from the remaining hidden piece of adhesive.
  24. When reassembling your phone, replace old adhesive with stretch release adhesive strips, double-sided tape, or pre-cut adhesive strips.

  31. Heat the top part of the glass with a heat gun or iOpener.
  32. The glue used for the display is tough and needs patience and gentle steady force.
    33. Step image
  33. When the glue is softened, insert a spudger through the camera bay in the midframe and push the display away from the frame.
  34. Place a plastic card or two opening picks under the display bezel at the top, between the screen and the frame. This will prevent the glue from readhering.
    35. Step image Step image Step image
  35. Insert an opening pick approximately 1/16 of an inch and slide it along the side to sparate the display from the frame.
  36. You might feel more resistance where the LCD ends on the lower end.
  37. Stop here and take your time to reheat that part and soften the glue.
    38. Step image Step image Step image
