Download the All New Redsn0w 0.9.9b1 to Jailbreak iOS 5, 4.3.5, 4.3.3 & More on iPhone, iPad & iPod Touch

Just the other day, we've brought to you a news where iPhone Dev-Team member MuscleNerd announced that his team will be giving the popular jailbreak tool Redsn0w, a major feature upgrade. Well good news to jailbreak fans out there, especially those who likes to use Redsn0w, the jailbreak tool has just been updated to version 0.9.9b1 and you can download it for Windows and Mac.

Redsn0w 0.9.9b1
One look at Redsn0w 0.9.9b1 and you will know that this is a very significant update to the program. One thing you will notice right away is of course the new interface. The change in UI is no way that dramatic but long-time users of Redsn0w should be able to tell right away. One of the most glaring drawback of using Redsn0w to jailbreak an iPhone, iPad or iPod touch is the fact that you are required to have an IPSW file of the firmware you plan to jailbreak into your device (Although there are cases where you'll need to point to a different IPSW file altogether). These firmware files can be rather large, so if you are regularly using Redsn0w, you will most likely need to keep a couple of IPSWs handy.

But with version Redsn0w 0.9.9b1, we're pleased to inform you that you won't be needing those bulky IPSW files anymore. Redsn0w will automatically detect your firmware version and will be fetching all the essential bits and pieces in order to apply the appropriate jailbreak. Although this particular feature is not yet applicable to all existing iOS 5 firmware due to the fact that it is still under beta. To which you will need to jailbreak your device the old-school way, by pointing Redsn0w to the IPSW file.

Check out the full change log for Redsn0w 0.9.9b1:

  • uses DFU mode to try to automatically determine which device and FW you have
  • fetches pieces of public IPSWs from Apple (once).  Non-public IPSWs must be provided manually (once).  It then caches those pieces for future use.
  • “Just boot” is a tethered boot.  Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
  • “Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
  • “Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails).  Should work on iOS5 beta too
  • “Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
  • “SHSH blobs” has a bunch of options…
  • “Fetch” - fetch current PARTIAL blobs on device.  Should complete in under 10 or 15 seconds.  Puts the set of PARTIAL of blobs on your computer as a plist.  Checks if Cydia already has a full set for this device and build.  If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
  • “Verify”  - cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server.  You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
  • “Submit”  - both verifies and submits one or more blob files to Cydia.  This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
  • “Query” - queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
  • “Stitch” - stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW
  1. Stitching is NOT yet supported on iPhones!  Need to work out the baseband part of the restore process.
  2. FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
  3. PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes.  No need to start TU or use Cydia though.
  4. Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores.  No need to start TU or use Cydia though.
  5. Will eventually support fetching the blobs directly from Cydia instead of a file on your computer.

Steps on how to Jailbreak your iPhone, iPad or iPod touch using Redsn0w 0.9.9b1:

  1. First you will need to download the new Redsn0w 0.9.9b1 for either Windows or Mac (download links are below this post).
  2. Launch Redsn0w 0.9.9b1 and you'll see two buttons on the main interface. To start jailbreaking your iDevice, simply click on the "Jailbreak" button and you will be prompted by the program to place your device to DFU mode. The process of placing your device to DFU is similar to previous Redsn0w versions, so just follow the on-screen instructions.
  3. redsn0w 0.9.9b1 Home
    Again if you are using regular, non-beta firmware, the new Redsn0w will automatically detect your device's firmware and apply the appropriate jailbreak (this means that Redsn0w will apply untethered jailbreak as long as the firmware version supports it). If you are running iOS 5 betas however, you will need to point Redsn0w to an IPSW file.
    redsn0w 0.9.9b1 DFU Mode

  4. And that's pretty much it, sit back and relax while the Redsn0w takes care of the rest. Under the Extras button, you'll find more jailbreak options such as booting in tethered mode, Pwned DFU mode, recovery fix, manually specify an IPSW and more.
  5. redsn0w 0.9.9b1 Extras1
    redsn0w 0.9.9b1 Extras2

And there you have it, the easy-to-use Redsn0w tool just got a whole lot better. With iOS 5 being just around the corner, expect that the iPhone Dev Team will release a swift update once the official final build is out. We can only hope that we'll get untethered jailbreaks once iOS 5 is finally rolled out by Apple.

    I have just jailbroken my 4.3.5 iphone 3gs and i now have cydia on my phone but the app is still white. When i have to reboot my phone through redsn0w, it tells me i need to specify an IPSW? what does that mean? P.S. I only jailbroke my phone because i have no sim card in my phone anymore and it is not syncing my music anymore.

      Hi,

      iOS 4.3.5 is still untethered, so you will need to use Redsn0w for a tethered boot in order to make Cydia work. And yes, you will be needing to specify an IPSW for the tethered boot, just select the 4.3.5 IPSW and follow the instructions.

      Hope that helps!!

      Hi,

      Don’t worry IPSW selection happens in Redsn0w, in your computer. :)

    Went all well on my iPad 1 3G + WiFi but the cydia app appeared blank and could not be accessed. One more thing is this a tethered jailbreak. What to do now.

      Yes, it is a tethered JB & therefore you need to boot your device tethered each time you shut down / reboot your iPad for the JB apps to work.

    when will it support getting the iphone 2g out of recovery mode?

    •  
      Pramod5 years, 2 months ago

      When did the iP2G get into a recovery mode in the first place? Its a 4-yr old iPhone which already can jailbroken & unlocked on its latest iOS version. Don’t expect any support for it from any of the recently released tools.

    Hello, I tried the new Redsn0w on my ipad 2, it did not work. it doesn’t support the Ipad 2. Any other suggestions?

      Ofcourse it doesn’t work on the iPad2. The iPad2 can be jailbroken ONLY on iOS 4.3.3 via JBMe.
