    [F.A.Q.] iREB 4.0.x-4.1-RC2. Как обойти ошибки 16xx ... - UiP

    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.

    Restoring Legacy Devices: A Guide to iREB 4.0.x / 4.1 RC2 If you are working with legacy iOS devices—like the iPhone 3G, iPhone 4, or the original iPad—you’ve likely run into the dreaded 16xx errors (1600, 1601, 1602, 1603, or 1604) in iTunes while trying to install custom firmware. iREB 4.0.x / 4.1 RC2, developed by iH8sn0w, is the classic tool designed specifically to bypass these hurdles and prepare your device for a smooth restore. What is iREB?

    iREB is a lightweight Windows-based application that puts your device into a "Pwned DFU" state. In this state, the device's bootloader is patched to accept custom IPSW (iPhone Software) files that iTunes would otherwise reject. Supported Devices for RC2

    This specific release is optimized for devices running iOS 4.x firmware: iPhone: 2G, 3G, 3GS (Old & New BootROM), and iPhone 4. iPod Touch: 1G, 2G (MB & MC models), 3G, and 4G. iPad: 1st Generation. Apple TV: 2nd Generation. How to Use iREB 4.1 RC2

    Using the tool is straightforward, but it requires precision during the DFU phase.

    Preparation: Close iTunes completely. Connect your device to your computer via USB.

    Launch iREB: Open the application and select your specific device from the menu.

    Enter DFU Mode: Follow the on-screen prompts to put your device into DFU mode. This typically involves: Holding Power and Home for 10 seconds.

    Releasing Power while continuing to hold Home until the computer detects the device.

    Wait for the Flash: Once detected, iREB will upload the necessary "pwned" files. You will know it's successful when your device screen turns a solid color (often white, red, or green).

    Restore in iTunes: Open iTunes. It should detect a device in recovery mode. Hold the Shift key (Windows) and click Restore to select your custom IPSW file. Troubleshooting Common Issues

    Device Not Detected: Ensure you are using an older version of iTunes (like 10.x or 11.x), as modern versions often lack compatibility with legacy DFU protocols.

    Stuck in Recovery: If your device is stuck in a recovery loop after the restore, tools like RecBoot or f0recast can often "kick" it back to a normal boot state.

    Are you planning to jailbreak your legacy device, or are you just trying to downgrade its firmware for better performance?
