: Use a tool like BalenaEtcher to write the .dmg file to a USB drive (minimum 8GB).
16 GB minimum capacity, preferably USB 3.0 for faster execution A7 to A11 Bionic devices (iPhone 5s through iPhone X) BIOS Mode UEFI Boot enabled (Legacy Mode is generally unsupported) Step-by-Step Installation Guide
The specific syntax in the file name reveals its configuration:
Always verify file hashes when available, and run the tools inside dedicated testing environments or secondary hardware rather than your primary workstation.
The 4g tag typically refers to the compilation version or integrated USB controller patches tailored for 4th-generation Intel chipsets and newer. This ensures your PC's USB 3.0/3.1 ports can successfully put an iPhone or iPad into Device Firmware Update (DFU) mode without dropping connection—the most fragile part of the checkm8 exploit. Step-by-Step Installation Guide
Intel Core 2 Duo or newer (AMD users must look for explicit "AMD" modified Ra1nUSB images).
The file contains a lightweight, custom version of macOS that includes the checkra1n utility. This specific variant ( intelnewrw4g ) is intended for computers with .
Ra1nUSB relies heavily on the checkm8 exploit, a hardware-level, unpatchable vulnerability found in Apple A7 through A11 bionic chips.
Note: Windows may show pop-ups claiming the drive is unreadable or needs formatting after completion. Ignore these prompts. Step 2: Configure the Target PC's BIOS
Before you begin, ensure your hardware meets the specific criteria needed for this image: Compatible Apple Devices (A7–A11 Chips) iPhone 5s through iPhone X iPad (5th, 6th, and 7th generation) iPad Air (1st and 2nd generation) iPad mini (2, 3, and 4) iPad Pro (1st and 2nd generation) PC Requirements
To permit the custom Intel kernel to load, change these settings inside your computer's BIOS menu (accessible via F2 , F12 , or Del at startup): Disable . Disable Fast Boot . Set SATA Configuration to AHCI Mode . Enable Virtualization Technology (VT-x) . Step 3: Booting and Launching Checkra1n
