Error 53: Apple remotely bricks phones to punish customers for getting independent repairs

All they do is pass the same hash for every input. You train it with your index finger, then you pass a hotdog over it, then you let your dog lick it, same hash every time…
They’re cheaper because instead of an actual AD chip with real code to figure margins for error and calculate a real hash it’s just some low-level logic to spit back a set value when nudged.
