  4. Lifting up the back cover

    To detach the back cover, we recommend using a thin, sturdy tool like the iFlex. Since it has particularly sharp edges, it can be inserted easily.
    1. Attach a suction cup to the lower edge of the back cover and pull it upward to create a narrow gap. At the same time, insert the iFlex between the screen unit and the back cover.

    To avoid damaging the edge of the case with the sharp edges of the iFlex, you should switch to a plastic tool like the iPlastix as soon as possible.

    Be extra careful when loosening around the camera module, so you don't damage it with your tool.

    1. Drive the tool completely around the edge of the back cover to loosen it piece by piece. Heat the adhesive again in between.
    2. Slide flat picks under the back cover at regular intervals, so that the glue cannot bond again.
    Used tools
  6. Unscrewing the board cover
