Ireb 4.0.x 4.1 Rc2.zip 1 <EXTENDED ✦>

iREB is a small utility historically used by iPhone and iPod Touch users to enter devices into a pwned DFU (Device Firmware Upgrade) mode so that custom or unsigned firmware images could be restored via iTunes or other tools. It was developed in the jailbreaking scene to assist users in downgrading firmware, restoring to custom IPSW files, or recovering devices that iTunes would otherwise refuse to accept due to signature checks.

A key feature of iREB 4.0.x-4.1-RC2 is its ability to bypass 16xx errors

(such as 1600, 1601, 1602, 1603, and 1604) in iTunes when restoring an Apple device to a custom firmware (IPSW). Key Benefits and Functions DFU Pwning

: It "pwns" the device's DFU (Device Firmware Upgrade) mode by uploading modified files (like iBSS). This tricks iTunes into accepting custom firmware created by tools like Sn0wbreeze or PwnageTool. Wide Device Support

: This specific version (RC2) supports a range of older Apple hardware, including: : 2G, 3G, 3GS (both old and new BootROM), and iPhone 4. iPod Touch : 1G, 2G (MB and MC models), 3G, and 4G. : iPad 1 and Apple TV 2. Simple GUI

: Developed by iH8sn0w, it provides a straightforward graphical user interface for Windows users to prepare their devices for custom restores without needing complex command-line knowledge. Are you currently trying to restore an older device to a specific iOS version?

iREB is a specialized utility tool developed for the Windows operating system, historically used during the golden age of iOS jailbreaking. Specifically, version RC2 targeting iOS 4.0.x and 4.1 was a critical instrument designed to assist users in bypassing specific errors encountered while restoring custom firmware (IPSW files) via iTunes. iREB is a small utility historically used by

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. Technical role

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.

The primary purpose of iREB is to patch the Apple Mobile Device (iBoot/iBSS) protocol to allow a "Pwned" state. In simpler terms, it tricks iTunes into accepting a custom, modified firmware file that Apple would normally reject.

During the iOS 4.0/4.1 era, users attempting to jailbreak their devices (using tools like Sn0wbreeze or PwnageTool) often encountered iTunes Error 1600, 1601, 1602, 1603, or 1604. These errors indicated that the device was refusing the custom restore. iREB was the fix for this, pushing the device into a state where it would accept the custom payload.
