By changing chips. There are already procedures for fun stuff like upgrading the RAM on the non-retina MacBook Airs to 16GB. Apple never offered 16GB version off that laptop but you can have it[0].
You clearly don't have a clue how modern Apple HW is built and why stuff that you're talking about on old Apple HW just won't work anymore on the machines build today.
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.
> I would love to be enlightened about the new physics that Apple is using which is out of reach to the other engineers.
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.
I know about it, it simply means that someone will build a device that automates the thing that the dude in Shenzhen does or they will mix and match devices that have different kind of damage. I.e. if a phone that has destroyed screen(irreparable) will donate its parts to phones that have the face id lens broken.
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.
I know Luis, he made a career of complaining that it's impossible to repair Apple devices when repairing Apple devices.
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.
Louis makes "Apple impossible to repair" videos since ever. It's not an iPhone 13 thing, give it a few year and you can claim that iPhone 17 impossible to repair, unlike the prehistoric iPhone 13.
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 don't. It's a technological progress similar to one where we lost our ability to repair transistors with introduction of chips. If this doesn't work for you you should stick with the old tech, I think the Russians did something like that on their soviet era plane electronics. There are also audiophiles who don't even switch to transistor and use vacuum tubes. Also the Amish who stick to the horses and candles who choose to preserve their way of doing things and avoid the problems of electricity and powered machinery.
You will need to make a choice sometimes. Often you can't have small efficient and repairable all the time.
