The story of iREB 4.0.x/4.1 RC2 (often found as iREB-4.0.x-4.1-RC2.zip) is a classic piece of iPhone jailbreaking history from late 2010. Created by the developer iH8sn0w, it was a critical utility during the transition from iOS 3 to iOS 4.1. The Problem: The Dreaded 16xx Errors
In 2010, Apple significantly tightened its security. When users tried to restore their iPhones (2G, 3G, 3GS, or 4) or iPod Touches to custom firmware (IPSW) using iTunes, they were frequently met with "Unknown Error" codes, specifically 1600, 1601, 1602, 1603, and 1604.
These errors happened because iTunes would check if the device was in a "pwned" state before allowing a custom restore. If the device was in standard DFU mode, iTunes would reject the custom firmware and fail the restore. The Solution: iREB (iH8sn0w's Recovery Bypass)
iREB 4.0.x/4.1 RC2 was the "Release Candidate 2" version designed specifically to "pwn" the DFU state of the device.
What it did: It uploaded three specific "pwned" files to the device using a USB exploit (like the limera1n or steaks4uce exploits).
The "Pwned DFU" State: Once iREB finished, the device’s screen would remain black, but it was now in a Pwned DFU mode.
The Result: iTunes would now "believe" the device was authorized to accept custom firmware, allowing users to restore to jailbroken iOS 4.1 IPSWs without any 16xx errors. Key Details of the RC2 Release Release Date: Around November 14–15, 2010.
Compatibility: It supported iPhone 2G, 3G, 3GS, 4, iPod Touch 1G–4G, iPad, and even Apple TV 2.
Requirements: It was a Windows-only tool that required .NET Framework 3.5 (interestingly, it often failed with .NET 4.0).
Successor: This version was quickly followed by RC3 to address minor bugs and expand support to iOS 4.2.1.
iREB 4.0.x/4.1 RC2 remains a legendary tool for legacy device enthusiasts, as it was the definitive way to "unstick" a device from a recovery loop or a failed custom restore during the early iOS 4 era.
iREB 4.0.x 4.1 RC2.zip is a legacy utility from iH8sn0w designed to place older iOS devices into a "pwned DFU mode," allowing for the installation of custom firmware.
