Step 2

              Heat the back panel glass
  • Prepare an iOpener and apply it to the bottom edge of the back panel for one minute.
  • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Step 3

              Apply a suction cup
  • Apply a suction cup to the heated edge of the back panel by pressing down on it to create suction, as close to the edge as possible.
  • If your back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken panel.

Step 4

              Insert an opening pick
  • Pull up on the suction cup with strong, steady force to create a gap between the back panel and the frame.
  • Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.
  • Insert the point of an opening pick into the gap.

Step 13

  • Continue swinging open the back panel until you can rest it on the left edge the phone, being careful not to put any stress on the attached ribbon cable.
  • During reassembly, this is a good point to power on your phone and test all functions before re-sealing the back panel. Be sure to power your phone back down completely before you continue working.

Hi, I am looking to replace my Pixel 4 motherboard and really appreciate the detailed guidance. However, I noticed that the motherboard replacement part is not offered through iFixit. Do you have a recommended genuine part supplier?

Thanks,

Patrick
