The Secure Enclave Processor manages the encryption keys for user data. Without valid SEP authentication, the data partition remains encrypted. Most A12 ramdisks can only access the system partition (which is uninteresting) or metadata. Full data extraction requires either the user’s passcode or a SEP exploit (like blackbird, which only works on older iOS versions).
The primary reason for building or booting a custom is to gain access when the main OS refuses to cooperate. Here are the most common scenarios: iphone xr ramdisk
: Resetting a device without updating it to the latest iOS version. The Ramdisk and the iPhone XR The Secure Enclave Processor manages the encryption keys
It allows "white hat" hackers to audit the file system, find vulnerabilities, and develop jailbreaks. Without ramdisk access, understanding the deeper layers of iOS would be nearly impossible. Full data extraction requires either the user’s passcode
