Introduction

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

You’ll need replacement adhesive in order to complete this repair.

What you need

Step 1

              Back Cover

Make sure the phone is powered off and placed with the back cover facing towards you on a stable surface.

Step 4

Insert a Jimmy under one of the heated corners of the phone to lift it slightly.
Insert a plastic card underneath the slightly lifted lip on the back cover and gently glide the card under the lifted phone casing.
There will be a small amount of tension, but this is normal as the card is removing the adhesive within the phone.
Remove the back cover from the phone.
Use high concentration (>90%) isopropyl alcohol and a lint-free cloth to remove all adhesive residue from the back cover and the frame.

Step 8

Grab the red tab on the right hand side and pull until the battery dislodges.
It will have some tension as there is tape holding the battery in place. Only remove the battery. Make sure to leave the tape as it will ensure the next battery stays in place.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

Does the adhesive for the back cover need to be replaced? Should I heat the phone and back glass for re-assembly?

Just wondering if anyone can clarify the reattachment of the rear panel, as far as whether it is recommended, or necessary, to heat it again, or get a new adhesive gasket. Thanks.

Good question! You should replace the back cover adhesive with either a custom-cut adhesive or double-sided tape such as Tesa tape. You can choose to reheat and reuse the existing adhesive, but there may be a chance that the back cover will fall off. If you’re reusing adhesive, be sure to remove any uneven adhesive chunks.

What width Tesa tape would work for the replacement of the back cover?
