Well it seems to me the problem itself is different-- I'm asking if there's any way to directly interface with the flash drive attached to the logic board. The issue w/ the san bernardino iphone, as I understand it, was that they had to bypass the PIN protection, which there was no way to do without dismantling the phone and potentially damaging the components. I just read an article that said a security researcher developed a method for forcing the iphone to disregard the number of attempts of PIN entry so that one could run through every possible permutation of a 4 digit PIN and crack it w/in 24 hours.
I'm assuming that, if you were able to somehow directly interface with the flash memory on the logic board, you wouldn't be prompted for a PIN. So the original question remains unsolved-- is it possible to directly interface with the flash memory of an iphone while it is physically detached from the phone itself, OR, alternatively, only attached to the [a] power source?
