Redsn0w 0.9.8b3: Tethered iOS 4.3.4 Jailbreak For iPhone, iPad And iPod Touch Released


iPhone Dev Team has released Redsn0w 0.9.8b3 for iOS 4.3.4 to jailbreak iPhone, iPad and iPod Touch.

Yesterday, Apple released iOS 4.3.4 to fix the security vulnerability that Comex had used in JailbreakMe 3.0, which is one of the easiest solutions to jailbreak an iOS device.

Dev team has provided the following information on their blog:

For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2.  The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is!  There are no new features in 4.3.4 — only fixes for jailbreak exploits.

Also, this is a good time to remind everyone (since we’re still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed.  This is unlike every other device, so don’t be confused!  iPad2 owners with basebands should stay away from all updates to maintain the jailbreak!

Redsn0w 0.9.8b3 supports the following iOS 4.3.4 devices:

Redsn0w 0.9.8b3 supports only a tethered jailbreak, which means that you need to connect your iOS device to the computer on every reboot.

So Dev team has advised users to avoid upgrading to iOS 4.3.4 if they want a untethered jailbreak and take a backup of SHSH blobs using TinyUmbrella for iOS 4.3.3 so that one can downgrade their iOS device if required. Apple still seems to be signing iOS 4.3.3 firmware file at the time of writing this post.

You can download Redsn0w 0.9.8b2 for Windows using this link and Mac using this link.

As always, let us know how it goes.

    Calm down bro, let’s see you come up with a jailbreak before you insult the people who liberated your device! Why should the guys throw away a perfectly good bootrom exploit just because it’s been in use since 4.1? Educate yourself on the way a jailbreak works before you assume that they all follow the same path.

  • darren Ward

    SausageHacker DUDE you dont know what your talking about musclenerd as done nothinf for us since ver 3

    limera1n is used to jb with redsnow geohot made it
    and @i0n1c only wrote the code for 4xx till 4.3.4 only

    so please know what your talking about before posting because you just look like a fool

    • SausageHacker

      Haha found this comment randomly, sorry for the 9 month late reply. Anyway, perhaps you’ve learned about jailbreaks by now. And yes, I knew what I was talking about, I hope you’ve matured since July 18 2011.

    Could someone please help me out, tying to jailbreak an ipod touch 4g 8gb that I updated to 4.3.4 (well my girlfriend did actually)…. Now when I am trying to jailbreak it, the redsnow programme gets stuck on exploiting limera1n so then I have to reset my ipod. I’m on windows xp so it isn’t a compatibility issue and I am running as admin.

    • Rajj

      Ihave the same problem with my iphone 4. I want to downgrade but it’s so diffucult. I’ve tried everything…

    • cedie

      i have the same problem with you but i already fixed it, what you need to do is as you enter dfu mode, you press the power button then the home button then release the power button but dont release the home button until the end of the program redsnow. hope it works for you

  • Jonyfiver

    I also cannot downgrade from 4.3.4 back to 4.3.3 on my iPhone 4, followed the steps but it goes into recovery loop, I have tried tinyumbrella and another recovery tool called scan something! It just reboots constantly then back to recovery?

  • Dileep

    Redsn0w 0.9.8b3 will hackviate iphone 4 running on ios 4.3.4 ???

  • Am stuck, ios 4.3.4 is failing to download from Itune,I would like to update my iphone 3gs,any one to help?

  • upon trying installing firmware 4.3.4 from other external sources other than itune i get error 1015

  • spenne

    everybody that got stuck in to the recover boot loop when trying do downgrade to 4.3.3, you must set your phone in DFU mode, the run fixrecovery wich you can download from tinyumbrellas homesite.
    it work for me:))

  • Herry

    I wait JB Full for 4.3.4

  • Andrew Whittaker

    If i get a tethered Jailbreak 4.3.4 and then downgrade to 4.3.3 can I then get an untethered jailbreak? Anyone? And what is this obsession with backing up your shsh blobs I use to downgrade all the time no problems with out doing that . Have apple changed something? Also why do we need to play around with host files?

    iphone 4 is not giving me notifications anyone knows about this problem???????:(

  • Philhanga

    A Little Help needed!! Can I use an AT&T issued iphone without paying for the AT&T dataplan? I have a new 3GS with version 4.3.5 fw. I have inserted my daughters SIM card from an older pantech into it. The SIM card is 2 years old and is a 3g SIM card registered to her number. My understanding is that AT&T will be notified that I am using an iphone and start billing my account anyway without me agreeing. I went into network settings and turned off the 3G and cellular Data options on the phone. I read somewhere that the SIM card tells AT&T that I am using an iphone through the IMEI number over the network. I do want to still be able to get on the Apple App Store and be able to use the wifi at home. I am open to jail breaking or downloading a fix if someone can walk me through it. I am new to this and its my first time. Any Ideas?
