Follow this guide to remove and replace the motherboard for the Pixel 3. The procedure involves removing many small grounding clips, which are easy to lose.

Note that removing the loudspeaker will compromise its ingress seal.

  1. Google Pixel 3 Motherboard Replacement, Weaken the back cover's adhesive: paso 1, imagen 1 de 1
  2. Google Pixel 3 Motherboard Replacement, Create a gap in the seam: paso 2, imagen 1 de 3 Google Pixel 3 Motherboard Replacement, Create a gap in the seam: paso 2, imagen 2 de 3 Google Pixel 3 Motherboard Replacement, Create a gap in the seam: paso 2, imagen 3 de 3
    • Apply a suction cup to the heated bottom edge of the back cover.

    • Make sure you did not mistake the screen side for the back cover side.

    • If your back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere.

    • Lift on the suction cup with strong, steady force to create a gap.

    • Depending on how aged your phone is, this may take significant force. If you are having trouble, apply more heat and try again.

    • Insert an opening pick into the gap.

    • Don't use metal tools to pry, or you'll mar or shatter the glass back cover. If the panel won't budge, apply more heat, either with a hair dryer or heat gun.

  3. Google Pixel 3 Motherboard Replacement: paso 3, imagen 1 de 1
    • When inserting an opening pick above the power button, be careful not to insert the pick too deeply, or you will damage the fingerprint sensor cable.

  4. Google Pixel 3 Motherboard Replacement, Cut through the adhesive: paso 4, imagen 1 de 3 Google Pixel 3 Motherboard Replacement, Cut through the adhesive: paso 4, imagen 2 de 3 Google Pixel 3 Motherboard Replacement, Cut through the adhesive: paso 4, imagen 3 de 3
    • Slice the adhesive along the bottom edge of the phone and around the right corner.

    • Leave a pick in the bottom edge to prevent the adhesive from re-sealing.

  5. Google Pixel 3 Motherboard Replacement: paso 5, imagen 1 de 3 Google Pixel 3 Motherboard Replacement: paso 5, imagen 2 de 3 Google Pixel 3 Motherboard Replacement: paso 5, imagen 3 de 3
    • Heat the right edge with an iOpener and continue slicing the adhesive with an opening pick.

    • The adhesive can be very gummy. Push the pick in and out in a sawing motion to help with slicing.

  6. Google Pixel 3 Motherboard Replacement: paso 6, imagen 1 de 3 Google Pixel 3 Motherboard Replacement: paso 6, imagen 2 de 3 Google Pixel 3 Motherboard Replacement: paso 6, imagen 3 de 3
    • Continue heating and slicing through the rest of the phone perimeter. Leave a pick in each edge to prevent the adhesive from resealing.

    • When slicing above the power button, do not insert the pick more than halfway in to avoid damaging the fingerprint sensor cable.

  7. Google Pixel 3 Motherboard Replacement, Lift the left edge of the back cover: paso 7, imagen 1 de 3 Google Pixel 3 Motherboard Replacement, Lift the left edge of the back cover: paso 7, imagen 2 de 3 Google Pixel 3 Motherboard Replacement, Lift the left edge of the back cover: paso 7, imagen 3 de 3
    • Once you have sliced around the perimeter of the phone, carefully lift the left edge of the back cover.

    • Do not attempt to remove the back cover. It is still attached to the phone by the fingerprint sensor cable.

    • Flip the back cover along its long axis and rest it so that the fingerprint sensor cable is not strained.

    • Remove the two 4.1 mm-long Phillips screws securing the fingerprint connector bracket.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

    • During reassembly, be careful not to over-tighten these screws, or you may damage your display.

    • Use the point of a spudger to slide the fingerprint connector bracket out from under the NFC coil.

    • Remove the fingerprint connector bracket.

  9. Google Pixel 3 Motherboard Replacement, Disconnect the fingerprint connector: paso 10, imagen 1 de 2 Google Pixel 3 Motherboard Replacement, Disconnect the fingerprint connector: paso 10, imagen 2 de 2
    • Use the point of a spudger to pry up and disconnect the fingerprint connector from its socket.

    • When you disconnect connectors like these, be careful not to dislodge the small surface-mounted components surrounding the socket.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

  10. Google Pixel 3 Motherboard Replacement, Remove the back cover: paso 11, imagen 1 de 3 Google Pixel 3 Motherboard Replacement, Remove the back cover: paso 11, imagen 2 de 3 Google Pixel 3 Motherboard Replacement, Remove the back cover: paso 11, imagen 3 de 3
    • Remove the back cover.

    • Before you install a replacement back cover, be sure to remove all adhesive residue from the phone frame. Use an opening tool to scrape and high concentration isopropyl alcohol to clean the surface.

    • If you are re-using the back cover, be sure to clean off any adhesive, and apply new back cover adhesive.

    • If you are installing a replacement back cover, be sure compare it with the original part. Transfer any remaining parts (such as the flash diffuser) over to your replacement part.

    • Slide the point of a spudger in the crevice underneath the black tape bridging across the battery and the motherboard.

    • Slide the spudger along the crevice to pry up the tape from the battery side.

    • Carefully peel the tape from the battery and fold it out of the way.

  31. Google Pixel 3 Motherboard Replacement, Disconnect the press connectors: paso 33, imagen 1 de 2 Google Pixel 3 Motherboard Replacement, Disconnect the press connectors: paso 33, imagen 2 de 2

Hallo,

wo bekomme ich denn ein neues Mainboard her? Ich komme nicht mehr ins recovery und vermute Mainboarddefekt.

Helge - Contestar

I followed your instructions to the letter. Got it all put back together, but before affixing the back glass, I powered up the Pixel 3 to make sure all features are working. The touch screen does not work, now, but it did before. Any advice?

Philip Wickstrom - Contestar

Hi Philip,

Does the screen light up? If it doesn’t, I would suggest disconnecting the battery connector and double-checking the display connector to make sure it is properly seated. As I looked into your question, I noticed that the step was missing a disconnection procedure—so thank you! I’ve amended that step.

Arthur Shi -

Where can I buy the motherboard? Is the 128 GB motherboard different from the 64 GB?

Orlando Terte - Contestar

muy interesante todo, seria bueno compartieras donde comprar la placa madre de reemplazo que sea original, para no caer en estafas, en mi caso se me rompió el regulador de voltaje del LCD el PM8005 y no tengo idea de donde lo venden para comprarlo, solo me queda la opción de una placa nueva. Si fueras tan amable de compartir donde comprarla te lo agradecemos. Excelente trabajo por cierto.
