: Streamlines entry into a modified DFU state to reduce common restore interruptions.

Developed by the well-known developer iH8sn0w , iREB (iDevice Recovery Mode Bypass) is a GUI application that helps users put their devices into a "pwned DFU mode".

: For Windows users, it is recommended to run iREB as an administrator and ensure iTunes is installed.

: Only download from reputable repositories like GitHub or known community mirrors. ZIP files from untrusted "hot" links can sometimes contain malware or unwanted bundled software.

: Open iTunes, hold the Shift key (Windows) or Option key (Mac), and select your custom IPSW to restore without errors. Safety and Compatibility

: Once the device is in DFU, iREB will run its exploit. If successful, your device screen may turn a specific color (like white or green) or remain black but be "pwned".

: Versions like RC2 were specifically optimized for iOS 4.0.x and 4.1, which were the primary firmware versions for the iPhone 3GS and iPhone 4 era.

: Attach your legacy iOS device to your computer via USB.
