With iOS 9 through 11, however, it is a headache. For iOS 7 and earlier, as well as for some early 8.x releases, the process was relatively easy. The only way to unlock the iPhone (5s and newer) is hardware-driven. At this time, no company in the world can perform the full physical acquisition (which would include decrypting the disk image and the keychain) for iPhone 5s and newer. All reasonably recent models (starting with the iPhone 5s and all the way up to the iPhone 7 – but no 8, 8 Plus or the X) can be acquired as well, but for those devices all you’re getting is a copy of the file system with no partition imaging and no keychain. For old models such as the iPhone 4s, 5 and 5c, full physical acquisition can still be performed, but only if the device is already unlocked and a jailbreak can be installed. Physical works like a charm for ancient devices (up to and including the iPhone 4). Physical acquisition rules if it can be done. It’s not a breakthrough discovery and will never make front page news, but having more possibilities is always great. We have recently made a number of findings allowing us to extract even more information from locked devices through the use of lockdown records. Pairing records are the key to access the content of a locked iPhone. Tired of reading on lockdown/pairing records? Sorry, we can’t stop.
