How practical is it to remove-restore-replace the NAND chip every 10 tries if you have to search through millions of combinations?

How practical is it to remove-restore-replace the NAND chip every 10 tries if you have to search through millions of combinations?
- jessaustin 11y agoPresumably you'd only have to remove it once, then install it in an easily-controlled circuit that would selectively connect it back to the rest of the phone?
- drakenot 11y agoIf the user was using a 4 digit pin code it would only be 10,000 combinations.
- voxic11 11y agoWhere do you get the millions of combinations figure?
- CIPHERSTONE 11y agoMaybe it was a type and he meant to say: >You see, a six digit passcode has one million possible combinations instead of 10,000.
- pbkhrv 11y agoWasn't a typo, I did mean "millions", see my comment above.
- pbkhrv 11y agofor passcode, iPhone supports 4-Digit numeric code (10k combinations), 6-Digit numeric code (1 million combinations), "custom numeric code" (arbitrary length, millions of combinations), or "custom alphanumeric code" (arbitrary length, millions of combinations)
- RickHull 11y ago> If it turns out that the auto-erase feature is on, and the Effaceable Storage gets erased, they can remove the chip, copy the original information back in, and replace it. If they plan to do this many times, they can attach a “test socket” to the circuit board that makes it easy and fast to do this kind of chip swapping. > If the FBI doesn't have the equipment or expertise to do this, they can hire any one of dozens of data recovery firms that specialize in information extraction from digital devices.
- ikeboy 11y agoAre there any data recovery firms that advertise the ability to do exactly what the FBI wants here?
- CamperBob2 11y agoOne obvious workaround would be to emulate it with an FPGA.
