: It bundles the Checkra1n jailbreak tool. Checkra1n utilizes the hardware-based checkm8 exploit, which targets vulnerabilities in the BootROM of Apple A7 through A11 bionic chips.
: This indicates a portable, USB-bootable environment configured primarily to run checkra1n , a semi-tethered jailbreak tool. Because checkra1n originally required a macOS environment to run, developers created "ra1nusb" images to allow users to boot into a lightweight, modified live environment specifically to deploy the exploit.
Because checkra1n is a hardware-level jailbreak (checkm8), this tool allows for jailbreaking even if the device is locked. How to Prepare and Use Ra1nUSB (Step-by-Step) Enable or UEFI Boot depending on your motherboard's

Because the Checkra1n jailbreak relies heavily on the hardware-based checkm8 exploit, it requires a Unix-based environment (like macOS or Linux) to properly execute USB commands. Ra1nUSB solves this for Windows users by packing a lightweight, modified live macOS environment into a single flash drive image. The intelnewrw4g variant specifically targets with updated drivers for modern read/write functionality ( rw ) and network configuration support.
