Apple has officially ended support for iOS 10.3.3 (iPhone 5/5c) and 9.3.5 (iPhone 4s). These devices are now considered "obsolete" by Apple’s hardware repair policy.
However, the checkm8 exploit ensures that the Dk Ramdisk method will work forever. There is no software update that Apple can push to these devices to stop the Ramdisk boot, because the flaw exists in the read-only bootrom. Dk Ramdisk Bypass Icloud IOS 9.3.5-10.3.3
That said, developers are moving on. Many tools that supported the Dk Ramdisk (like Sliver or Checkra1n) have dropped support for iOS 9-10 to focus on iOS 14-15. Users today often have to compile the Ramdisk manually using Legacy iOS Kit. Apple has officially ended support for iOS 10
Pro Tip: If you plan to keep a bypassed device running for years, disable OTA updates via the Ramdisk (rm -rf /mnt1/System/Library/CoreServices/SoftwareUpdate.bundle) to prevent accidental reboots. Using a tool (like ipwnder or gaster ),
Using a tool (like ipwnder or gaster), a Mac or Linux computer sends the checkm8 exploit payload to the device. This bypasses the signature checks, allowing the execution of custom code.
Unlike modern "signal" bypasses that rely on DNS tricks or hacked SIM cards, the Dk Ramdisk method is a filesystem-level jailbreak. Here is the technical breakdown.
