Redsn0w 0.9.6b4 Download Available Now

Nov 23, 2010 - 65 Comments

redsn0w 0 9 6 b 4 download Redsn0w 0.9.6b4 has been released for download by the iPhone dev team, and it allows you to jailbreak iOS 4.2.1, but there’s a catch; not all hardware get an untethered jailbreak. Redsn0w 0.9.6b4 only supports the following devices for untethered jailbreaks: iPhone 3G, older iPhone 3GS, and older iPod touch 2G models. All other iOS devices will have to be plugged into your computer with redsn0w launched each time you reboot the device (or your battery dies). For this reason, I would recommend most people wait on trying to jailbreak iOS 4.2.1 until another untethered solution is available.

Download Redsn0w 0.9.6b4

You can grab the latest redsn0w release for Mac or Windows:

Note about unlocking iOS 4.2.1
If you plan on unlocking your iPhone, do not update to iOS 4.2.1 and do not use redsn0w for now because it will update your baseband. Unlockers should save SSH blobs from their current firmware (iOS 4.1 or earlier) and wait for a PwnageTool update so that you can upgrade to iOS 4.2.1 without updating the devices firmware. If you update to 4.2.1 you risk losing the ability to unlock your iPhone.

Update about unlocking iOS 4.2.1
You can get the redsn0w 0.9.6b5 download which will work to jailbreak iOS 4.2.1 and allows you to unlock iOS 4.2.1 with ultrasn0w for iPhone 3G and iPhone 3GS.

Update 2: redsn0w 0.9.6b6 download is now available and helps to resolve battery drain issues with unlocked iPhone 3GS and 3G models.

Update 3: Redsn0w 0.9.6rc8 is out.

  9. thood says:

  10. Jordan says:

    hey so i’ve used this version of redsn0w before on my ipod but after restoring it i went to re-jailbreak it and redsn0w is not recognizing it in dfu mode.. It comes up on my computer as “Apple Mobile Device (DFU Mode)” But it’s not showing up in redsn0w.. Anyone with the same problem or a solution?? that would be very appreciated

  11. help says:

    mine is stuck when the redsn0w displays exploiting with limera1n.. process bar fills up half soon after starting but doesnt increase after that.. waited 2 hours.. tried 3 times.. out of luck.. ipod 3g, mc, 4.2.1… can any1 help??

    • the dude says:

      mine got halfway thru the limera1n thing and froze halfway through, then i realised I was using wrong firmware, it’s not all that easy to tell between models of ipod touch unless you check by serial number on the back of the ipod in the smallprint (under the bit that says 8gb, 32gb etc)

  12. Cally says:

    There’s even problem to open redsnow!!!

  14. nate22297 says:

    Ok so i have an ipod touch 2G MC model, and on the Dev team blog it says itll work with 2G MC but as a tethered, but when i select my firmware in redsn0w it says that the iPod touch 2G MC is not supported yet? anyone know why? I already tried running as administrator and in XP Compatability mode. (using windows 7)

  15. StyleKrong says:

    Thank you so much for this, you have no idea how long I was searching for a working JB for the Iphone4. TYTYTY! :D

  16. help says:

    Can someone help me? after intalling redsn0w i opened cydia and asked me to upgrade then i turned off my itouch. after that i turned it on again and cydia wont open anymore.

    • KingKhan says:

      It may have been the the tethered version of jailbreak you had because on the tethered version if you switch of your phone off you will have to do the prosess again. So open up redsnow and click browser and the file you need to select is iPhone3,1_4.2.1_8C148_Restore, after that click next and then make sure the only option that is selected is Just Boot Tethered Right Now

      Just try that and it should be up and running and if it isnt then you may have to install the whole cydia thing again

  17. WH says:

    the download link for windows is down, please reupload it..
    thanks

  24. kyle says:

    man forget Redsn0w it isnt working for 1/2 the people on this page and obviously is a joke. if you cant fix the problems associated with the program then dont publish it. thx

  25. Houtsy says:

    NO, PEOPLE ARE JUST DUMB AND DONT LISTEN!!!
    YOU MUST RUN REDSNOW IN WINDOWS XP COMPATIBILITY MODE AND RUN AS ADMINISTRATOR!!!
    THEN IT WORKS FINE!!!

  26. Darkfayt says:

    It seems far too many people are complaining and posting problems before reading any comments on the board, if you just read above posts, all questions are answered. Instead of being lazy and posting the same questions repeatedly and pissing off the people who can and will help you, make sure it’s not answered. I’m getting sick of seeing the same post fifteen times from different people when the answer is already posted several times.

  27. Darkfayt says:

    Just followed the instructions in the tutorial and above posts, and guess what? It worked fine. iPod touch 2g mb model for those who are curious.

    Hi,

    I am trying to unlock my iphone 3gs(4.2.1 8c148a) as i don’t have the sim to be activated.

    I am using resnow 0.9.6b6 and the 4.2.1 restore firmware for jailbreaking. I am runnig the exe file in the XP service pack 2 compatabilit mode and as an administrator but still it gets strucked up at the exploiting with limra1n.

    Could anyone please help me on this.

  31. Jake says:

    OK, so I’ve looked through all the comments and responses and I’m certain my issue has not come up/been resolved.

    On iPod 2G MB, I get through everything, and when it says its finished, the screen is blank

    I never get a “downloading jailbreak data” and the icon to come up. Instead, its just a black screen.

    Could anyone please help? This would be much appreciated.
