Follow this guide to remove a cracked or broken screen for the Moto X4.

As part of the procedure, you will have to transfer the fingerprint sensor from your broken screen to the replacement part.

  1. Before you begin, turn off your phone. Heat an iOpener and apply it to the left edge of the phone for two minutes.
    • Before you begin, turn off your phone.

    • Heat an iOpener and apply it to the left edge of the phone for two minutes.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • 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.

    • As you wait, take note of the the following areas:

    • Display cable—be careful not to slice too deeply near the edge here, or you may damage the display cable.

    • Fingerprint sensor cable—be careful not to slice too deeply near the edge here, or you may damage the fingerprint sensor cable.

  2. Apply a suction cup to the screen, as close to the heated edge as possible. Pull on the suction cup with strong, steady force to create a gap in the seam. Insert the point of an opening pick into the gap.

    • Insert the point of an opening pick into the gap.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply heat to the edge and try again.

  3. Slide the opening pick along the edge to slice through the adhesive. Leave an opening pick in the seam to prevent the adhesive from re-sealing. Leave an opening pick in the seam to prevent the adhesive from re-sealing.

  4. Heat the top edge of the phone with an iOpener. Carefully slice around the corner and through the top edge to separate the adhesive. Carefully slice around the corner and through the top edge to separate the adhesive.
    • Heat the top edge of the phone with an iOpener.

    • Carefully slice around the corner and through the top edge to separate the adhesive.

  5. Heat the screen's right edge with an iOpener. Be careful not to slice too deeply near the cables to avoid damaging them. Use an opening pick to slice along the right edge to separate the adhesive.
    • Heat the screen's right edge with an iOpener.

    • Be careful not to slice too deeply near the cables to avoid damaging them.

    • Use an opening pick to slice along the right edge to separate the adhesive.

  6. Repeat the previous steps to heat and slice the bottom edge of the phone. Repeat the previous steps to heat and slice the bottom edge of the phone.
    • Repeat the previous steps to heat and slice the bottom edge of the phone.

  7. Do not try to remove the screen yet—it is still attached to the phone by delicate flex cables. Carefully lift up the left edge of the screen and cut away remaining adhesives with an opening pick.

  8. Swing open the screen and prop it up with a small box as you work on disconnecting the flex cables.
    • Swing open the screen and prop it up with a small box as you work on disconnecting the flex cables.

    • During reassembly, this is a good time to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

  9. Slide the point of a spudger underneath the fingerprint sensor cable and gently pry up to loosen the cable from the phone. Do not pull on the cable. It is still attached to the phone by a delicate ZIF socket.

This guide really only covers screen removal, and should detail replacing the screen as advertised. Here are a few more steps that should be added:

1. Transferring old hardware to the new screen (seals, filters, fingerprint sensor, & the grey carbon mat.

2. Cleaning up old adhesive.

3. Applying new adhesive, whether it’s the one-piece that ifixit carries (recommended), or Tesa tape.

4. Installing the new display assembly

Is it possible to remove and replace only the glass? Can I do that without removing the whole LCD screen and avoid disconnecting/reconnecting wires?

Drew S - Ответить

Hi Drew,

I haven’t tried, but I think it is possible to do a glass-only repair for this LCD screen, as long as you have the necessary tools and bonding adhesives. You would still have to deal with the fingerprint sensor, which is sealed onto the glass.

I noticed the fingerprint sensor not being quite as low on the right edge after this. Also, I think it has a bit of “give” now when I press on it with a thumbnail. If the tips of my thumbs weren't so dry right now I might not have noticed, though.

I just finished following your guide and mostly satisfied. Somehow my fingerprint sensor doesn’t work but <shrugs> If I loose that convenience for a time, then I still payed less and got experience. Now, for the constructive criticism. YOU NEED a re-assembly guide. We’re not all at the level you guys are and it took a lot more work for me to put things back together as I had to flip things around and watch a few other videos to see steps I missed. You need a guide because you some of the items you’re supposed to use are not mentioned here because they’re not used until you re-assemble it. Please add it to this guide (for future people) unless you’re going to stop selling this kit, then just add it to the other kits. It would be a great help.
