I mean this kinda sucks since when your device is in a BFU state the people calling wont appear as contacts but who doesnt touch their phone for 3 days in 2024 anyway

Idk, every unstable system requires a reboot at least once a week. Otherwise, system performance will feel slower than usual.
@NilanjanMustafi29 күн бұрын
Once every 7-10 days when I try to unlock my iPhone 13 on iOS 17.4.1, iOS asks me to first enter my password. Is that same as what's shown in the video i.e., BFU or is that AFU? Also, when I press the power + volume buttons together for a couple of seconds and don't shut down my iPhone, it asks for my password. Is this BFU or AFU?
@jiskac26 күн бұрын
Both scenarios you describe are AFU. The second one restricts some interfaces but disk stays decrypted. You can easily try that out when calling your iPhone: In BFU, no contact info is shown. In AFU, contact info from your address book is shown.

Oh now I get it, that’s why sometimes when I’m trying to swipe up my phone it needs a passcode first because it reboots 😅😅
@jiskacАй бұрын
Not necessarily. Apple also put some other mitigations in there that require you to enter the passcode under certain conditions. In some of these cases, the iPhone didn't reboot and is still in After First Unlock state.
@JamesR624Ай бұрын
The fact that the reboot is in verbose mode is interesting. Apple usually *really* doesn't allow things like that on production releases of software.
@TurboPikachuАй бұрын
That’s because it’s a research device. That iPhone is likely Apple’s property that they’re allowing devs to use for testing purposes. Inactivity reboot is going to be a normal reboot on end-users’ iPhones

is this for like re-encryption?
@tdrg_Ай бұрын
Yeah, in BFU state pretty much all user data is encrypted
@busterscrugsАй бұрын
Yup, prevents law enforcement from accessing data from your locked phone.
@Tougebeat28 күн бұрын
Is this the same encryption as with a factory reset?
@michaelthornes24 күн бұрын
this resets the phone from an AFU (after first unlock) state to BFU (before first unlock) state, part of this meaning encryption keys are purged from memory and you must use your pin/password instead of just biometrics to unlock the first time. this makes it more difficult for law enforcement or other phone thieves in general to access the data on the phone, because they need to get the encryption keys, there are no potential bypasses, memory-related or otherwise

It's an Apple Security Research Device. Apple loans you a phone (which isn't for personal use) It's used to find, test, validate, verify, and confirm a vulnerability
