The back cover is scratched or broken.

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!

    Do you want to open your smartphone or lever out large parts like the battery? Then the iPlastix with its large blade will help you. The practical assistant is made of flexible, especially sturdy plastic and lies comfortably in the hand. Thanks to its design, you can even get into smaller gaps, for example to lift the screen or to prevent it from sticking together again.

  • iSclack


    Opening your device can be a real test of patience, when the screen or back of your phone is glued very strong. With an iSclack, you can simplify the process. The pincer-like handle allows you to create a gap between the screen and the frame with minimal effort. At the same time, you have the other hand free to use a narrow tool such as a plectrum or the iFlex to enlarge the gap. The included cover foils allow you to use the iSclack even if the screen is splintered.

Getting started with the repair of your Xiaomi Mi 9

If you get stuck or have questions, you can post a comment. We’d be happy to help.

3 steps
  1. Switching off the Xiaomi Mi 9

    1. Turn off your device by holding down the power button until the “Power off” option appears.
    2. Use your finger to confirm that you want to shut down your device and wait until the screen goes blank.
  2. The right tools for your repair

    With the right tools, you will succeed in any repair. In our store you will find a large selection of professional quality tools.
  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).
