A close person got hit by a car and died a few years ago. The persons iPhone flew trough the air. The police was not able to turn it on and mentioned that it would be impossible to collect data from it. (Which might would have helped to solve the case). Back then iPhones had the status "quite damn save". One had to invest a lot of effort into reading the encrypted data from the hardware.
I recently found out that this iPhone is still lying around. I got concerned that the LiPo might catch fire. Therefor I have put the iPhone somewhere save. That was when I noticed that after years of electrical engineering at university and some advances made in iPhone penetration, I might be able to collect some data from it.
What is the current situation? I assume NSA would be able to read some data from it. Since it is already an old phone, would I be able to do so? The iPhone was heavily damaged due to the impact. Which parts would need to be intact? Is it enough if the flash is alright? I have another iPhone 5 which I could use to solder in the flash drive. But I remember something like there is a hardware encryption key in many parts of an iPhone. Thats why I fear transplanting the flash would not work, since it would stay encrypted.
I have the password and everything from the original owner. Therefor I would not have to crack that. But I suppose it's not just a little soldering work. What would have to be done to make it work?
(I don't want to talk about if I should do this. It is already too late to change something. Case is closed. It is more about the technical aspects. And of course I would be thankful if some clarifying facts arise.)
