En hoe krijg je ‘m dan weer goed dicht?
If the original tape won’t hold anymore, you could replace it with double sided adhesive tape to reseal the back cover. Take a look here:
or directly in the EU Store for shipping to the Netherlands:
When I opened up my phone to replace the battery, almost everything in this guide was still correct except that now the battery is screwed in with 1.2mm star screws.
This guide worked for me.
But during step 3, the tabs ripped off, and I had a hard time separating the battery from the back cover.
So instead I used a tweezer to disconnect the battery (step 5), and slowly pried the battery off, along with the back cover. After that, you can have more space to work with removing the battery from the cover.
