Dev Team Releases Redns0w 0.9.9b8 To Jailbreak iOS 5.0.1 Beta

Redsn0w

iPhone Dev team has released a new version of Redsn0w – Redsn0w 0.9.9b8, which supports iOS 5.0.1 beta that was seeded to developers yesterday.

With the latest version of Redsn0w, developers don’t have to use the trick of pointing to iOS 5 firmware file.

iPhone Dev team have provided the following information on their blog:

redsn0w version 0.9.9b8 will natively recognize the 5.0.1 beta that Apple let developers start testing this week (so you don’t have to play the “point at 5.0 IPSW” trick).  Because the IPSW isn’t public, you’ll still need to provide it once to redsn0w (at which point it will cache all the important pieces so you don’t need to select it again).  

For those 3GS and i4 users who preserve their baseband, the Mac version can also produce the NO_BB_* custom IPSWs for 5.0.1.  (But please note that ultrasn0w doesn’t get updated for betas like this.)

This is still a tethered jailbreak for all except old-bootrom 3GS users.

Redsn0w 0.9.9b8 supports the following iOS 5 devices:

Redsn0w 0.9.9b8 supports only a tethered jailbreak for iOS 5.0.1 just like iOS 5, except for iPhone 3GS with old bootrom which is untetherd. It doesn’t support iPad 2 and iPhone 4S. After developers have jailbroken their iOS device, they can use the SemiTether hack, which allows users to reboot their tethered jailbroken iOS 5 device without the need to connect it to the computer.

Developers can download the latest version of Redsn0w using this link for Mac and this one for Windows.

  • Manny

    Oh great.
    All jailbreaking effort is going into an iOS version which hasn’t even been released yet, instead of producing a usable untethered jailbreak of iOS5.

    • Bob

      Yea stop complaining.. Ur worthless.. Apple will release 5.0.1 really really soon like in couple of weeks so it be stupid of them public jb for a version that eats up battery.. Stop being pathetic!

  • Peter

    Pay for them then you thief

  • Peter

    Pay for them then

  • Nivek

    You’re supposed to back up before syncing, so een if it does delete those apps they’ll be on your comp

    Just let us know when an untethered JB is available. Geeze, now i know how android users feel. Waiting forever for something that everyone else had for months…

  • Peter

    And that’s a fair use of it however it’s quite clear iPhone 3GS isn’t doing that

  • twoforone

    what happens if they release an untethered for i4, do we need to rejailbreak it?

  • Stu

    i hope the iphone 4s gets a jailbreak sometime b4 iOS 6.0 is jailbroken

  • wentbackward

    Cannot break IOS5 on iPhone 4. Did the JB, did the reboot, got the brown cydia icon, it runs initially, starts downloading stuff, says reloading data, then exits and will not restart after that. I can now reboot the phone using redsn0w, but Cydia will just say loading… for a few secs then die. Any help?

    • polumbianprncess

      that’s happening to me to when you go on cydia does it say this device is in the pending tss queue? cause its not fully jail broken and i don’t know how to get rid of it its been weeks.

  • Jason

    I bought an Iphone 4 recently and it had 4.3.3 on it. Sweet! Untethered jailbreak. I want to give ios 5 jailbreak a go, but am afraid I will not be able to go back to 4.3.3

    I notice in cydia it says it has shsh for 4.3.5 which was a tethered jailbreak, but no the shsh for ios 4.3.3.

    does anyone know if I jailbreak, worst case will I be able to go back to 4.3.3 or is 4.3.5 the lowest I can go back to because of what cydia says?

    • Eric

      You can. Use iFaith to back up your phone (it extracts your SHSH-blob and signs a IPSW-file with it, ready to just easily install with Itunes).

      I did. It worked.

  • chrystal

    i have tried a few times to jailbreak my iphone 4 from sprint and every time it gets to waiting for rebot it dont do anything and i have to restart my iphone. anyone know what im doing wrong? im new to this. thanks

    • Steve1010

      No. Cydia only has 4.3.5, so you cannot downgrade. Stick with your 4.3.3 and jailbreak it with jailbreakme or whatever available out there.

    • Steve1010

      No. Cydia only has 4.3.5, so you cannot downgrade to 4.3.3 should you ever screw up with the JB. Stick with your 4.3.3 dude.

      • Jason

        It’s a iPhone from sprint iOS 5

  • gurupkar

    now that ios 5 is out, should’nt the untethered jail break for 4.3.5 should be out

  • BDog_Grizzly

    Okay, I don’t understand what is taking so long to Jailbreak the A5 chip. It’s been out for several months and yet there isn’t a single jailbreak for it. I don’t mean to sound ungreatful but I am really frustrated that this has taken so long. I have an iPhone 4S AND an iPad 2. No jailbreak, no sign of one hitting anytime soon and no one seems to be working that hard to get one out. Come on guys, I’ve donated at least $300 over the years and I’d like a jailbreak sometime soon.

  • Jason

    What I don’t understand is why no-one has responded to my above question. Seriously everyone bitching about getting untethered and 4s jailbreak but no-one can spare 2 seconds to answer a simple question.

    • Steve1010

      I have. Did you read?

    • Steve1010

      You can also try using tinyumbrella to back up your 4.3.3 to Cydia and see if they are willing to sign for it. I suppose you already knew how to verify you ssh blob?

      • Jason

        Sorry, didn’t see you replied on someone else’s post. Thanks.

  • Karhick

    Just do the untethered jailbreak for 4.3.3…. That’s the smart thing to do atleast for now…..

  • Popero44

    We need an untethered jailbreak for iPhone 4s T_T

  • Hainguyen

    Please help me. I follow the instruction on redsn0w tool to jailbreak my ip 3gs, ios 5. When the process is at DFU mode (release power button and hold home button in 15 seconds), my ip powered off and then I cannot power it on again.

    • Trickdawg

      Oooooop’s time to pay the Apple Store a visit….!

  • Soccy

    I have an ipod 4 touch running OS 4.3.5. It is on a tethered jailbreak. Should I go ahead and update to 5 and just use that tethered jailbreak? Is there any significant improvements in v.5?

  • Swanified

    I just jailbreaked my iphone 4 using redsnow 0.9.9b8 to jailbreak 5.0.1 beta but ended up using ios 5.0.
    Now I cannot get mail on my iphone. The mail server is not responding. How do I fix this.
    Neither Gmail or Hotmail accounts work for me.
    Thanks.

    • Jr

    iphone continues to show this screen and doesn’t start.
    please help……..

  • OldJailbreaker

    I have an old iPhone 3gs that I want to jailbreak, but every time I try, it tells me I can’t do an untethered install, but I don’t want to. I’m not sure where that option is or if I’m doing something wrong. Do I need an active SIM card for this to work? Or can I jailbreak an old phone that has an old SIM card in it? IDEALLY, I’d like to sell it unlocked and jailbroken, but not sure how to go about doing that. I”M SO LOST!!!

  • Wes

    I really do not understand why a solid jailbreak has not been done yet, as I search relentlessly everyday. I am not going to hook this phone up to the computer when it shuts down. I am surprised because there are jail broken apps that I have paid for and I don’t understand why the people who have benefited from this financially are not doing something about it. This iPhone is good but not great, and I have an upgrade available, I might as well get android so I can do what I have been lacking since I updated my phone thinking from all the talk that a jailbreak would be only a few days away, I mean a real jailbreak. This sucks.

  • moso mosu

    The method works well on my old 3GS. Arigato Gozaimas

  • Max

    Why it doesn’t work with iPad2? Will it soon?

  • David

    Hey for all you jailbreaker out there who know how to create software why dont you try to creating a software to trick ios 5 into thinking it running on a older verison to then use a old untether jailbreak
