iBoy Ramdisk is a Windows-based software tailored for iOS servicing. It exploits hardware vulnerabilities (often utilizing the checkm8 exploit) to load a custom RAMdisk onto an iOS device. Because this RAMdisk runs entirely in the device's temporary memory (RAM), it bypasses the standard iOS security checks. This allows technicians and advanced users to: on Hello screens.
If you are worried about someone using an iBoy RamDisk + ECID extraction to access your iPhone, here are mitigation strategies: iboy ramdisk ecid register
Registration is often required to unlock the "Boot Ramdisk" and "Bypass Hello" buttons within the software. Follow these steps to get your device ready:

For A12+ devices, no ramdisk method (including iBoy) can bypass a strong passcode (>6 digits) due to the SEP’s counter and per-ECID key derivation.

Once the device is successfully "pwned", select the correct iOS version matching your device and click Boot Ramdisk . Execute Desired Operation: If you are bypassing a passcode, click Backup Passcode . If you are bypassing a Hello screen, click Bypass Hello .
