I used this tutorial to first inspect and then replace a faulty fingerprint reader. I noted a couple of things I’d change in this guide, as well as a notes on replacing the fingerprint sensor assembly. In this guide:
(1) I’d recommend having '''Tesa 61395 Tape''' in 4 mm in addition to a replacement '''rear cover tape kit'''. The areas noted in step 5 are areas where the adhesive is likely going to need to be replaced. Also, the adhesive securing the fingerprint reader will need to be replaced, as it does not stand up well to removal by prying.
(2) The replacement cover adhesive sold by iFixit is only ~2mm wide. The original is ~ 4mm wide for more contact area. Given the importance of this to the IP68 rating, I’d like to see full thickness adhesive to the original spec. See the picture in step 13, above, to see the dimension on the original adhesive.
(3) Reassembly is slightly more complex than simply reversing the steps. A bit of direction of reapplying adhesives and re-seating the fingerprint assembly would be useful.
It doesn’t appear that the battery needs to be removed before the motherboard, either in this teardown or when poking into my device. Given the way the battery is adhered, I’d prefer to get the motherboard, and all it’s sensitive components, out of the way first.
The bracket is an integral part pf the button assembly. The detent mechanism on the back of the button PCB needs the bracket to press against to activate.
Has anyone else run into the different screws holding the midframe? I opened my son's phone today to swap out the battery and found the screws to be tri-wing. Imagine my confusion. I've been into to my wife's Nexus 5x before, and it has phillips-head screws. Weird.
This step MUST also include a note to disconnect the power and volume ribbon cable and cover at the top left of the device.
Dave Lee on YouTube has a much more helpful note on removing the back cover. That video is available at: https://youtu.be/Yk1CGk0TZAw?t=1m20s
This ZIF connector is covered in amber anti-static tape, which needs to be released from the connector side before the ribbon can safely be pulled free.
It would be instructive to add that one needs to remove the whole ribbon assembly by lifting the whole thing from its semi-fixed position on the motherboard. I did so using the blunt end of a spudger to lift the two small flaps along the right edge of the motherboard and lifting the whole complex off the motherboard with tweezers.
