Logic Board Removal

ID: 175701

Description: This guide shows how to remove the logic board...

Steps:

  1. Let your Pixel's battery drain below 25% before starting this repair. A charged lithium‑ion battery may catch fire if damaged.
  2. Unplug all cables and completely power down your phone.

  4. Adhesive secures the perimeter of the rear cover to the frame.
  5. When separating the adhesive, don't insert your tool more than 3 mm under the rear cover to avoid damaging the internal components.
  6. Measure 3 mm from the tip and mark your opening pick with a permanent marker. Alternatively, you can tape a coin to a pick 3 mm from the tip.

  8. Attach a suction handle to the bottom edge of the rear cover, as close to the edge as possible.
  9. Step image Step image
  10. Pull up on the suction handle with strong, steady force to create a small gap under the rear cover.
  11. Insert the tip of an opening pick in the gap.
  12. Step image Step image Step image
  13. Slide your opening pick along the bottom edge to separate the adhesive securing it.
  14. Remember: don't insert the opening pick deeper than 3 mm.
  15. Step image Step image Step image
  16. Slide your opening pick up the left edge and along the top edge to separate the adhesive.
  17. Step image Step image Step image
  18. Slide your pick down the right edge to separate the remaining adhesive.
  19. Step image Step image Step image
  20. Don't try to fully remove the rear cover yet, as a ribbon cable on the right edge connects it to the phone.
  21. Use the suction handle to lift the left edge of the rear cover and swing it over the right edge, like opening the cover of a book.
  22. If you're having trouble, check the perimeter for any remaining adhesive and use your opening pick to separate it.
  23. Prop up the rear cover with the suction handle so you can access the ribbon cable near the top right corner.

  25. Use a Torx Plus 3IP screwdriver to remove the two 5.2 mm‑long screws securing the cable cover.

  31. Remove the rear cover.
  32. During reassembly, follow this guide to apply new adhesive and install your back cover.
  33. Step image
  34. Use the tip of a spudger and your fingers to peel up the piece of tape near the left edge of your phone, enough that you can access the bracket and screws underneath.
  35. You can completely remove the tape if you want, but be sure to keep it for reassembly.

  51. Use a Torx Plus 3IP screwdriver to remove the 5.2 mm‑long screw securing the mmWave antenna cover.
  52. Step image Step image
  53. A tight metal clip secures the bottom left corner of the mmWave antenna cover.
  54. Insert the point of a spudger under the tab near the bottom left corner of the mmWave antenna cover.
  55. Use your spudger to slide the cover to the right while prying up to unclip the cover.
  56. Step image Step image Step image
  57. Gently pull the right edge of the cover towards the bottom of the phone and remove the cover.
  58. During reassembly, insert the two tabs on the top corners under their recesses in the frame and push the cover down to clip it into place.

  62. Use the point of a spudger to pry up and disconnect the front facing camera press connector.
  63. Step image Step image
  64. Be very careful not to touch the cameras during this step. If you accidentally do, wipe them with a clean microfiber or lint‑free cloth.
  65. Carefully hold the front facing camera cable out of the way so you can access the mmWave antenna screw.
  66. Use a Torx Plus 3IP screwdriver to remove the 4.2 mm‑long screw securing the mmWave antenna.
  67. Step image Step image Step image
  68. Use tweezers or your fingers to remove the mmWave antenna.
  69. During reassembly, make sure the mmWave antenna goes under the front facing camera cable.
  70. Step image Step image
  71. Use a spudger to pry up and disconnect the three remaining press connectors along the bottom edge of the logic board—two larger press connectors near the center and one smaller one on the bottom right corner.
  72. Step image Step image Step image
  73. Use a Torx Plus 3IP screwdriver to remove the two 5.2 mm‑long screws securing the metal cover in the top left corner.
  74. Step image Step image
  75. Use tweezers or your fingers to remove the cover.

  77. Use the point of a spudger to pry up and disconnect the autofocus sensor press connector from the top left corner of your phone.
  78. Gently fold the cable up so you can access the antenna connector beneath it.
  79. Step image Step image Step image
  80. Slide one arm of your angled tweezers under the metal neck of the antenna connector and lift straight up to disconnect it.
  81. During reassembly, use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
  82. Step image Step image
  83. Use a standoff screwdriver to remove the 4.8 mm‑long standoff screw from the bottom right corner of the logic board.
  84. If you don't have a standoff screwdriver, you can use a flathead screwdriver that's as wide as (or slightly wider than) the screw. To avoid stripping, make sure the driver is properly aligned with the screw and apply continuous downward pressure.
  85. Step image Step image Step image
  86. Use a spudger to pry up the top edge of the logic board until you can grip it with your fingers.
  87. Grip the right side of the logic board and carefully remove it, being careful that no cables get snagged (one front facing camera cable and four cables along the bottom edge).
  88. During reassembly, hold the front facing camera cable out of the way and lower the logic board into place, making sure the four cables along the bottom edge don't get trapped underneath.
  89. Step image Step image Step image
  90. During reassembly:
  91. Check the condition of the logic board thermal pad—it will either be on the bottom of the logic board or on the frame.
  92. If the pad is undamaged, skip the rest of this step.
  93. If the pad is damaged, use the flat end of a spudger to scrape it up and remove it.
  94. Use isopropyl alcohol (greater than 90%) and a microfiber cloth to remove all thermal pad residue from the frame and bottom of the logic board.
  95. Apply a new thermal pad to its spot on the frame.
