Redsn0w for windows

Redsn0w 0.9.5 for windows has been released and here is the step by step guide on jailbreaking iPhone 3G/3GS And iPod Touch 2G on Windows.

Please note that before applying this jailbreak for iOS 4 through Windows, you need to have an official carrier SIM card because there is no unlock tool bundled.

  1. The first step is to make sure that you have already activated your iPhone3G/3GS or iPod Touch 2G with iTunes and your iDevice is running iOS 4.
  2. Now download redsn0w 0.9.5 for Windows and keep the installation file on your desktop [ or wherever you prefer].
  3. After this, navigate to Redsn0w file you just downloaded and execute it. Click “Browse” and select iOS 4 .IPSW file that you used for updating your device through iTunes.
  4. Now check “install Cydia” radio button and click next.
  5. After this you will need to power off your device and connect it to your Windows based Desktop/laptop. Please double check if your device is properly powered off and is properly plugged into the computer.
  6. Now boot your device in recovery mode by simultaneously pressing down “power” and “home” button.
  7. After this, swiftly press down “power” button along with “home” button. After some time, release the power button while still holding on to the home button until you can see installation begin.
  8. Now release the home button and wait for the installation to complete. Your device will reboot automatically after installation and you will have your iPhone 3G/3GS or iPod Touch 2G jailbroken on iOS 4.

  4. Burn…. Now I have the new baseband. I hope I’m not effed for a jailbreak come the 21st! I need my lockinfo back!! *tear*

  5. It is NOT working on 3gs. This version of redsnow was released for 3g and 2g and it does not work for 3gs.

  6. I get the same error. Is there another version of the firmware we need somewhere to use with redsnow?

  7. Hi
    I’m getting the same issue. I’ve downloaded 4 different versions of iOS4 GM ipsw from different sources but nothing is working.

    Everytime Redsn0w states “Unable to recongize specified IPSW”.
    I’ve seen a couple of threads on other forums with people having the same issue but they are all being ignored, I assume no-one has a clue why this is happening.

    Any help would be appreciated.

  8. I tried this…. FAIL.

    I restored to iOS 4 and downloaded and ran redsn0w_win_0.9.5b5-1

    Located my IPSW

    Redsn0w tells me “Unable to recognize specified IPSW”

    BTW your download link for redsn0w doesn’t work… i managed to get it from somewhere else….

    • Will you please be able to post the link you have downloaded the redsn0w from?
