The exploit reads the ECID from the chip’s security fuses. This ECID is then used to decrypt a pre-compiled ramdisk image that matches the device’s hardware and iOS version. Some tools create a ramdisk on the fly, stitching the ECID into the image header to satisfy Apple’s cryptographic checks at the bootloader level.
The most effective iBoy RamDisk implementations rely on the (disclosed by axi0mX in 2019). Checkm8 affects all devices with A5 through A11 chips: iboy ramdisk ecid register

“iBoy ramdisk ECID register” encapsulates a specialized, technical workflow: extracting a device’s ECID, binding that identifier into device‑specific artifacts, and using those artifacts to boot or manage a ramdisk for recovery, analysis, or development. Mastery requires careful attention to device‑specific signals (ECID, board IDs, nonces), respect for legal and data‑integrity boundaries, and up‑to‑date knowledge of Apple’s evolving boot security.
