Replace the cracked or scratched back of your Xiaomi Mi 9

In just three easy steps, we'll show you how to change the back cover of your Xiaomi Mi 9. All you have to do is be patient when removing the defective back cover. It is glued all around, so you have to loosen the glue first to remove the back cover. We show you how to do this and with patience, some plectrums and heat you will reach your goal.

Do not settle for a broken back cover - simply replace it yourself and enjoy the clear back again!

  • iPlastix

    iPlastix

    Taking apart the little pieces in your smartphone can be a big pain. The iPlastix is tough but thin with a blade thickness of just 0.15 mm, so it fits into even the smallest spaces, like the gap between the display and frame or under the logic board. The iPlastix is made of durable plastic and designed for a good grip, making this convenient tool the perfect assistant for every smartphone repair.

  • iSclack

    iSclack

    You can’t repair your iPhone or iPad until you get the device open. That may sound simple, but it can be a very tricky, complicated process. How can you hold onto everything, and how do you take apart the different pieces? How do you do that without breaking something else? The handy iSclack opening tool makes opening your device a lot simpler and safer. The two suction cups face each other to grip your display and back cover. The handle works like a pair of pliers so you only need one hand to move both parts. Thanks to the included screen covers, you can use the iSclack even on a cracked display.

  3. Removing the back cover

    1. The back cover’s heavily glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
    2. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
    3. Heat the spot where you start and place a flat tool between the back cover and the frame.
    4. Use a suction cup to lift the glass if you can't find a place to insert your tool.
    5. With the iSclack, you can easily lift the back cover and then use a flat tool to loosen the glue. Put both suction cups on the display and the backcover and press the lever of the tool together like a pair of pliers.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert. The iFlex makes it easier to get into the gap between the glass and the frame because it's made of very thin, stable metal. But it also makes it easier to scratch the frame of your device.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.
    3. Once the rear glass is unglued, you can lift it off.

    The covers of the cameras remain in the device and are not permanently attached to the back cover. Loosen the adhesive there as well and take care not to damage the flex cable of the covers.

  4. Attaching the new backcover

    1. Remove all plastic film above the adhesive surfaces on your spare part.

    Remove the adhesive around the camera cover when new adhesive is present on the new back cover.

    1. Position the back cover over the device and press it down when it is exactly in the center.
    2. Heat the glue one last time and press the backcover on. You can weigh the device down with books or use clamps to compress the glue as long as it cools down (about 10-20min).
