Anyway, people are crafty and engineering is not an Apple-exclusive trade. believe it or not, Apple can’t do anything about the laws of physics.
That’s known as private-public key crypto with keys burnt into efuses on-die on the SoC.
You can’t get around that (except for that one dude in Shenzhen who just drills into the SoC and solders wires by hand which happen to hit the right spots). But generally, no regular third party repair shop will find a way around this.
You know, these encryption authentications work between ICs and not between lenses and motors. Keep the coded IC, change the coil. Things also have different breaking modes, for example a screen might break down due to the glass failure(which cannot be coded) and the repair shop can replace the broken assembly part when keeping the IC that ensures the communication with the mainboard. Too complicated for a street shop? Someone will build a service that does it B2B, shops will ship it ti them, they will ship it back leaving only the installation to the street shop.
Possibilities are endless. Some easier some harder but we are talking about talent that makes all kind of replicas of all kind of devices. With billions of iPhones out there, it's actually very lucrative market to be able to salvage 1000USD device, their margins could be even better than the margins of Apple when they charge 100USD to change the glass of the LCD assembly.
Watch Luis Rosmann on youtube.
Instead of watching videos and getting angry about Apple devices being impossible to repair, I get my Apple devices repaired when something breaks. Significantly more productive approach, you should try it.
Your old Apple devices, that are known to be vert easy to repair. You wouldn't be so confident with the latest gear.
But why spoil it for you? Let's talk in a few year when you find it out the hard way on your own skin.
Here is a video from 2013, him complaining that Apple doesn't let people repair their products: https://www.youtube.com/watch?v=UdlZ1HgFvxI
He recently moved to a new larger shop in attempt to grew his Apple repair operations. Then had to move back to a smaller shop because as it turns out, it wasn't Apple who is ruining his repair business.
You will need to make a choice sometimes. Often you can't have small efficient and repairable all the time.
I'm talking about 2020 devices where you can't just "change the chips" and hope it works like in the 2015 model from the video you posted.
Modern Apple devices aren't repairable anymore.
