Follow this guide to remove and replace a broken fingerprint sensor for the Mate 10. The process is very extensive, requiring the removal of many heavily-glued-in components.

Note that the procedure will destructively remove the screen. The Mate 10 uses very strong adhesive to hold the screen in place, making non-invasive removal very difficult without specialty tools.

Gaining access to the fingerprint sensor also requires removing the firmly glued battery. Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

The back cover held in place with a very strong perimeter adhesive. During removal, the adhesive may rip out parts of the coating from the glass back cover, leaving behind patches of clear glass.

    • Heat an iOpener and apply it to the bottom edge of the phone for two minutes. Re-heat the iOpener as needed.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone.

    • While you wait, note the location of the adhesive holding the back cover in place.

    • Place a suction cup near the bottom edge of the back cover, on the right side (opposite the speaker grille) of the USB-C charging port, above the microphone hole.

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

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

    • Due to the adhesive's strength, this is very difficult and may take multiple attempts. If you can't create a gap, re-apply heat and try again.

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

    • After you cut through the adhesive around the entire perimeter of the back cover, begin to lift it away from the phone.

    • Use an opening pick to slice any remaining adhesive.

    • Remove the back cover.

    • During reassembly, this is a good point 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.

  7. Huawei Mate 10 Fingerprint Sensor Replacement, Prep the phone for a new back cover: step 7, image 1 of 2 Huawei Mate 10 Fingerprint Sensor Replacement, Prep the phone for a new back cover: step 7, image 2 of 2
    • Before you install a replacement back cover, be sure to remove all traces of perimeter adhesive from the phone frame.

    • If you are re-using the back cover, carefully remove all traces of adhesive from the back cover.

    • The glass back cover is fragile and prone to cracking. Don't apply uneven pressure to the back cover as you clean.

    • You may pull up chunks of the cover's color coating as you remove the adhesive. To reduce the chances of this occurring, apply heat or high concentration isopropyl alcohol to the adhesive to weaken it.

  8. Huawei Mate 10 Fingerprint Sensor Replacement: step 8, image 1 of 2 Huawei Mate 10 Fingerprint Sensor Replacement: step 8, image 2 of 2
    • If your replacement back cover did not come with a flash diffuser or camera bezel, you will need to transfer them from your old cover to the new one.

    • Apply a heated iOpener directly over the bezels for a minute.

    • Use an opening pick to slice around the flash diffuser to loosen the adhesive.

    • The flash diffuser is made of plastic and cracks easily. Be sure to slice around the flash completely before you pry it off.

    • Use an opening tool to pry up and remove the camera bezel.

    • Transfer the parts to your replacement cover.
