Redsnow 0.9.9 B5 released to Jailbreak iOS 5 / iOS 4.3.3 on iPhone, iPad and iPod Touch

December 11, 2011 Leave a comment

Redsnow 0.9.9b5 is rolled out by iPhone Dev Team to support iOS 5 jailbreak on all devices except iPad 2. However, it is to be noted that this version provides tethered jailbreak on iOS 5 devices. Those users who are still looking for untethered jailbreak on iOS 4.3.1, iOS 4.3.2 and iOS 4.3.3 can still use Redsnow 0.9.6 RC16. First we will post the complete step by step guide for iOS 5 users and after that some lines about previous jailbreak.

If you rely on iPhone Unlock, never follow this guide. Head over to this post for complete step by step guide on “How to Unlock iOS 5″ to unlock and jailbreak your device at the same time.

Redsn0w 0.9.9 b5 to Jailbreak iOS 5:

Note: All those users who rely on unlock must not try this guide. In fact they must not upgrade their devices to iOS 5 otherwise they may lose the unlock ability forever.


  • iOS 5 Firmware [the links are at the bottom of this guide]
  • iTunes 10.5
  • Redsn0w 0.9.9 b5
  • And of course an iPhone or iPad/iPod Touch


Step 1: Download iTunes 10.5 and install it on your PC.

Step 2: Sync and back up your iPhone using iTunes.

Step 3: After you have backed up your device, update it to iOS 5.

Step 4: Download Redsn0w 0.9.9 b5 and launch it.

Step 5: Click on “Jailbreak” option.

Blank Cydia

Step 6: Now select “Install Cydia” and if you want to use the Multitask Gestures on iOS 5, select the third option too, as shown in this picture.

Step 7: Switch off your device and put it into DFU mode. Follow the on-screen instructions to ener DFU mode. The instructions are:


  • Switch off your device.
  • Hold down the power button for 3 seconds.
  • Without releasing the Power Button, hold down the Home Button too.
  • Keep pressed both buttons for 10 seconds.
  • Now release the Power button but keep pressed the Home button for further 15 seconds.
  • You will see a blank (black) screen that indicates your device is in DFU mode.

Step 8: Sit back and let Redsn0w do the rest of the work. Redsn0w will install the required files on iPhone.

Step 9: After your device restarts, you will notice a new icon named “Cydia” which might be blank at this stage. Now again launch Redsn0w, go to Extras and select “Just boot” option. Follow the on-screen instructions which are similar to Step 7.  Now when your device restarts you will notice “Redsn0w logo”. After the deice has restarted, you can see “Cydia” icon.


Fire up Cydia, tap on User option and start installing your favorite tweaks and Cydia apps. If you want to get further help on this jailbreak guide for iOS 5, please follow us on Twitter/Facebook.

Redsn0w 0.9.6 RC 16 to Jailbreak iOS 4.3.3/iOS 4.3.2/iOS 4.3.1:

Redsnow 0.9.6 RC16 has been released to jailbreak iOS 4.3.1 [iOS 4.3.2] and iOS 4.3.3. This new and updated version provides untethered jailbreak on all idevices except iPad 2.

Update: Redsnow RC16 is now available. It fixes side switch vibration issue on iPhone 4 and iPhone 3GS. For more details head over to this post.

As usual Redsn0w 0.9.6 is available for both Windows and Mac users. Head over to “How to Jailbreak iOS 4.3.1 Untethered Using Redsn0w 0.9.6 RC9 [HowTo Guide]” for complete step by step jailbreak tutorial.

Redsnow 0.9.6 RC15 Update Notes:

… three in a row!  Apple released iOS 4.3.3 on Wednesday, and once again the untethered jailbreak exploit that@i0n1c created for 4.3.1 still works.  That makes it an unprecedented three firmwares where the same userland exploit works.  We’re not exactly sure why Apple hasn’t fixed the hole yet, but we’re not complaining!

Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!).  It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak.  The 4.3.3 untether works on all devices that actually support 4.3.3 except for the iPad2:

  • iPhone3GS
  • iPhone4 (GSM)
  • iPod touch 3G
  • iPod touch 4G
  • iPad1
  • AppleTV2G (v4.3 8F202)

Some things to note:

  1. ultrasn0w unlockers must stay away from redsn0w!  Use only a custom IPSW to update to 4.3.3, to avoid updating your baseband. There are plenty of tutorials for both redsn0w and PwnageTool at sites like shoutpedia.  Or feel free to ask away in our comments section below.
  2. ultrasn0w has been updated to v1.2.3 to be compatible with iOS 4.3.3 and earlier (the ultrasn0w update does not include any new baseband support!).Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.3.
  3. By popular demand, redsn0w now allows you to enable multitasking gestures (although most will find it useful only on iPads).
  4. iPad2 update:  The iPad2 jailbreak remains under development.  As you may know, the original exploit @comex developed in the first week of the iPad2 release was mysteriously fixed by Apple within days of its development.  Partly because of this, don’t expect much public discussion of the iPad2 jailbreak until it’s actually finished and ready for release (and please avoid asking about it).  In all liklihood, it will be a userland exploit like the first (unreleased) one, not dependent on bootrom dumps.  The first one can’t be released even for those with the original 4.3 firmware due to legal (distribution) reasons.

As always, please feel free to ask for help or advice in our comment section, with out friendly moderators Confucious, sherif_hashim, dhlizard, Frank55, and subarurider (and many other very knowledgable commenters too!)

Other Redsnow Updates:

  • Redsnow 0.9.6 RC 12 adds the option to enable boot animations and removes some misleading information from settings related to side switch. You can read the more details in our this post.
  • Redsn0w 0.9.6 RC13b is now available to jailbreak iOS 4.3.2 on all idevices except iPad 2. iPhone 4 untethered jailbreak support has been dropped from this update due to some problem on this model. Tethered jailbreak is still possible on iOS 4.3.2 using this new version. Download RC13b from here.
  • Redsnow 0.9.5 RC14  provides untethered iOS 4.3.2 jailbreak on all idevices including iPhone 4 but except iPad 2. Get it here.

If you have already jailbroken (tethered) your device using the early version of Sn0wbreeze or Unofficial PwnageTool bundles, you can simply run the Redsnow over it to get untethered jailbreak.
