RedSn0w 0.9.9b1 Now Available To Download For Windows And Mac OS X

As promised by iPhone Dev-Team member MuscleNerd, RedSn0w 0.9.9b1 has been released and is available to download for Mac OS X and Windows. RedSn0w 0.9.9b1 supports all iDevices except iPad 2 (which can be jailbroken on iOS 4.3.3 with JailbreakMe 3.0) and can jailbreak tethered the iOS 5 betas, iOS 4.3.5, iOS 4.3.4 (Verizon iOS 4.2.10, iOS 4.2.9) firmwares, and jailbreak untethered the iOS 4.3.3 or lower firmwares.

RedSn0w 0.9.9b1 change-log:

Update #9:  A bunch of new features!

  • 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

    “…untethered the iOS 4.3.3 or lower firmwares.” Does this mean it works for 4.2.10 too?

  • Jaden

    As far as I know this supports an iOS 4.2.10 untethered Jailbreak, however, I have not tested this myself so I cannot say for sure.

  • Kate Chopin

    not downloaded it yet, but i wanna know something abt its support for iOS 4.2.10 too which is to be confirmed by webmaster.

  • KK

    Tried it and restored. The JB happened all right but the phone refused to exit safe mode no matter how many restarts of springboard one did. And there is the fact that it is a tethered JB, which can be quite a pain really. The software works well, just that I prefer untethered. Think I will wait for public release of iOS 5 and a stable jailbreak. Besides it appears a lot of the apps still aren’t OS 5 compatible. Thanks team!

    I used Redsnow 0.9.9b1 and iPhone3,1_4.3.5_8L1_Restore on my iPhone4 ( (4.3.5 (8L1) and 04.10.01) and all the process was smooth and rebooted with the pineapple et all. However, I still cannot use a Swiss SIM card. Is it the fact that it’s Swiss or that the above firmware is not intended for iPhone4 BUT for iPhone3? Sorry if it’s a retarded question, just wondering (and hoping someone will answer)…

     Jailbraking does not automatically mean that you unlock the phone. Jailbreak = enabling software installations and modification, unlock = allowing other carries and SIM card to be used. A big difference :-)
