How does this work? I’d have thought those flash chips would be something customised specifically for Apple and contain some kind of authentication system or preprogrammed ROM with immutable firmware - or at least have the IMEI number burned into it somewhere - surely there’s some mechanism for an iPhone to detect unofficial (or unofficially installed) storage chips and prevent booting?
Are they sourcing actual Apple chips that get leaked or diverted out of Apple’s presumably locked-down supply-chain?
- userbinator 7y agoAt least for the older models, they used standard flash chips (eMMC?) --- there wouldn't have been official Apple models with that large of a capacity at the time anyway.

- ClumsyPilot 7y agoI don't think there is much to customise in a flash chip. There comes a point where a part is so basic and integral to the device that putting these kind of protections is outright impossible - without them the phone might not exist as a computing device.
