    • Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible.

    • Lift the rear glass with the suction handle to create a gap between the glass and the frame.

    • Insert an opening pick into the gap.

    • If the glass wont budge, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

what adhesive can you use to glue the back on and the fingerprint scanner to the back?

Polly - Responder

Hi Polly,

you can either buy pre-cut adhesive for your device/rear glass or use thin double sided adhesive tape you cut by yourself. For example you can use this tesa adhesive card.

Can you remove the fingerprint component from the old back cover? I just want to replace the cover as it is cracked and the fingerprint sensor is still working great.

Hi Dannoe,

the fingerprint sensor is glued to the back cover. To transfer the fingerprint reader you need appropriate custom cut adhesive to adhere it to your new back cover. You should be able to remove it by placing and iOpener for about 1 minute onto the back cover where the fingerprint reader is located (following the iOpener instructions) and carefully sliding an opening pick underneath the edges of the reader to separate it from the back cover. Be especially carefully in the area where the chip is located and avoid overheating it. Good luck with your repair!
