Redsn0w 0.9.6b5 Download Available

Nov 28, 2010 - 99 Comments

redsn0w-0-9-6-b-5-download Redsn0w 0.9.6b5 has been released for download for both Mac OS X and Windows, and it allows you to jailbreak iOS 4.2.1 on iPhone. This new version of redsn0w is particularly valuable to those wanting to unlock their iPhone from baseband 05.14 and 05.15 because it prepares the iPhone 3GS and iPhone 3G for unlocking with ultrasn0w.

Redsn0w might also be considered easier to use since the application will automatically download the iPad IPSW 3.2.2 file from Apple rather than you having to do it yourself, meaning you only have to point at one IPSW file, which is your own jailbroken version.

Download redsn0w 0.9.6b5

You can grab the latest beta 5 version of redsn0w 0.9.6 for Mac or Windows:

  • Download redsn0w 0.9.6b5 for Macclick here
  • Download redsn0w 0.9.6b5 for Windowsclick here

Note: these links have been updated to download the rc16, the newest version of redsn0w.

Be sure to keep your device plugged in and powered via USB throughout the entire jailbreak process with redsn0w. For Windows 7 and Vista users, be sure to run redsn0w as Administrator in “Windows XP Compatability Mode” to avoid any errors.

The functionality of Redsn0w 0.9.6b5 is similar to PwnageTool 4.1.3 in that it allows you to upgrade to 06.15 baseband (from the iPad) which is vulnerable to the newly released ultrasn0w 1.2 unlock. This is currently the only way you can unlock certain versions of iPhone baseband.

Update: A new version of redsn0w has been released, you can now download redsn0w 0.9.6rc8, the new version is recommended for all.

    Redsn0w stuck on “waiting for device to reboot” screen.

    Usually I would fix this problem by saving Redsn0w under C/program files/common files/apple/apple applications software, then running it as administrator.
    BUT the Redsn0w is a zipped file and won’t extract!! I get a WinRAR Diagnostic Msg…

    Any suggestions anyone?
    I’m on a PC, iOS4.1 and 05.14.02 firmware. I’m looking to unlock.

  6. Christiaan says:

    Ah I think i solved the prob.

    You don’t have to save Redsn0w in C:/, save it anywhere but make sure to tick the iPad bassband box when jailbreaking with Redsn0w.

    Thanks me

    My Redsn0w Crashes when uploading to ramdisk… an the hardrive icon shows in the iphone… iphone 3gs 4.2.1… Im using XP… any ideas…

    • Brado says:

      I am having the exact same problem. Done it twice now with a reboot in between attempts. I’m going to go home and try it with a mac to see if I have any more success.

      I’m on a 3G locked to rogers with 4.2.1 and baseband 5.15…

    • Jonathan says:

      Had the same problem. you have got to start redsn0w and then gointo the the task manager (press alt+ctrl+del). There you have got to go to the tab processes. Right-click on redsn0w and click on the last option. There you have to deactivate CPU0 and let CPU1 on. If you want to be sure that there will nothing come between the process of jailbreaking give redsn0w a high priority too.
      Hope this helps some of you.

      • Dracule says:

  11. Juan says:

    Iphone 3g, i had the issue where it will get stucked on “uploading ramdisk”
    im using Windows 7. it went through right after I selected the compatibility mode to windows XP.
    So bottom line. you have to run redsnow under Windows XP. and if u have windows 7. right click the program and select windows XP

    Guyz – Those getting stuck at “uploading to Ramdisk”….

    Hit run as administrator, then open Task Manager, click on Redsn0w and set Affinity to CPU1 only.. back out and continue through tethering (or initial loading with Cydia)…… Works every time like a champ.

  17. bb says:

    3GS 4.2.1 old bootrom

    Jailbreak: Needed Redsn0w 0.9.6.b6 – set to XP compatibility mode (windows 7 enterprise), ran as administrator and set affinity of Redsn0w process to CPU 1 only. This was after 2 failed attempts with the older versions. Thanks to everyone on every forum that I’ve read.

  21. Kevin says:

    I have a iPhone 3g with 4.2.1, it was jailbroke with the 4.1, but i had to do a factory restore. So i am trying to jailbreak it again and everytime i am stuck on the waiting for reboot everything else runs smoothly, i set the affiniti to cpu1 only, run as admin, priority high, compatability mode to win xp (im using win 7) and tried to do it with upgrading to ipad baseband….any suggestions?? Thanks in advance for any help

  22. Yasin says:

    Hi guys, I was having the redsn0w crashing problem on Vista too.

    To alleviate it I did all of the following:

    - Right clicked redsn0w and selected compatibility mode to windows xp service pack 2

    - Clicked ‘run as administrator’

    - Once opened I then pressed ctl alt del, went to task manager, selected ‘show processes from all users’, accepted the UAC notification, then right clicked on redsn0w and selected ‘set affinity’ and selected only one cpu (deselect all but one of the cpu’s)

    This worked perfectly.

    Thanks for all the comments and help.

  23. Yasin says:

    i have an ipod touch 2g running on 4.2.1 firmware. i tryed using redsn0w n greenpois0n but none of them work n it’s fustrating. Can somebody help me please!!!!

  32. PGTips says:

    A lot of people are getting stuck in DFU mode (Apple screen boot loop).

    Try REC Boot or Easyirecovery (google) if one doesn’t work the other will. You may also need Microsoft .NET framework 4.0 which you can get from windows update free of charge.

    Happy iDevicing

  41. Saleem says:

    Hey guyz,
    I am having a weird problem. I am trying to unlock iphone 3G modem 05.15. . The thing that is happening with me is that redsnow gets stuck at fetching i pad baseband for a little while and then suddenly closes. I tried all the affinity, priority, and even tried to do it on XP, XP service pack 2 and 3. Also tried it on i mac but the same problem persists. I am in Saudi Arabia does that have something to do with it or is there some other better solution to this problem!

  42. rkx1 says:

    Same problem dude :/
    Im in ireland so doubt location has anything to do with it

    • John says:

      We struggled repeatedly and I figured out a solution last night. We followed the process and selected each attribute to be installed EXCEPT the iPad Baseband. Then we did the process again, and ONLY selected the iPad Baseband. Worked like a charm.

    Hi I am really struggling to unlock and jailbreak my iphone 3g, which is on 4.2.1 filmware and 05.15.04 baseband. I have downloaded, redsn0w 0.9.6b5 and ipad 3.2.2 filware and iphone 4.2.1 filmware. My issue is when i run redsnow, i don’t get an option to install ipad baseband. Do you have to be on the latest itunes? I’m not sure what I am doing wrong, do I need a higher redsnow file? Pls could someone help me and provide me with a link if possible, as I have been going round and round and feel somewhat dizzy

    Hey guys,

    when your redsnow craches after your ramdisk, you maybe not have the right version of your iphone on your computer. If you want to know what version your iphone really haves, and you cant see that because he is locked or something, just download tinyumbrella, it wil say what version your iphone is. and with a site , you can download your version
