I'd go so far as to say line the holes up first before you secure the rest of that part. There is no room for error here!
This step was surprisingly hard - the plastic guitar pick was a bit finer and made it easier. Perhaps some heating helped as well?
I can recommend preheating - first phone attempted without preheating both strips broke almost instantly, but this time heating the back of phone until battery felt about 40 degrees made for a smooth removal, saving me ages prying it out with cards…
Scary thought - did you manage to find one?
Haven’t had any issues with any of the screws so far. Nothing stuck or even threatening to strip. Could it be that people are using the wrong driver bit and getting into trouble that way? You regularly have to swap between tri and normal 4 blade Phillips heads, best to double check each time.
Its in the toolkit now. Looks like a Philips head but up close the end is squared off with a point in the middle.
This was an oddly challenging step, lifting the speaker slightly from the top end allowed me to slide the tips of one side of the tweezers in between the cable and the speaker, prying it out rather than grabbing and pulling which feels dangerous.
I agree, these guides are half imaginary idealism it seems. A thin metal edge pushed vertically down just a fraction of a mm will cause the adhesive to weaken better than any amount of heat, but affects the final appearance sadly.
