Conclusión

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

To reassemble your device, follow these instructions in reverse order.

The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place.

Take your e-waste to an R2 or e-Stewards certified recycler.

What size tape do you use to reapply?

Tim Bottomley - Contestar

The battery doesn't need to be replaced. Taking it out is entirely unnecessary and the relevant steps in this guide can simply be skipped.

Astrodoge - Contestar

Hi Astrodoge,

that‘s right. However due to the phone’s design, we recommend removing the lithium-ion battery in order to remove the screen and have better access to the components. We mention this in the introduction of this guide.
