Download Redsn0w 0.9.9b4 With Improvements For iOS 5 Users

by Ahmed Omar on October 9, 2011

The iPhone Dev Team has quitely released redsn0w 0.9.9b4 which comes with some improvements for iOS 5 users. The 0.9.9 b4 version is made for those who want to test their own custom RAMDISKS using the -r command line option. In case you’re one of them, you will have to use the below commands mentioned on the Dev Team blog.

Redsn0w 0.9.9b4 Download

Full changelog:

Update #12: For those of you who experiment with your own custom ramdisks using the -r command-line option, version 0.9.9b4 adds auto-detection support for iOS5. This is needed because iOS4 and iOS5 treat the root partition differently (it’s encrypted in iOS5). redsn0w will now upload the correct iOS5 kernel by itself, but it’s up to your own launchd to determine if it needs to mount using the old or new partition scheme.

redsn0w now also accepts both native and img3-encapsulated versions of files you provide via the -r, -k, and -d command-line options (do redsn0w -h to show all the available options).

For those who wants to jailbreak iOS 5 GM on all devices tethered using the new redsnow 0.9.9b4, you can head over our previous guide posted here and follow the steps but use the below download links of redsn0w 0.9.9b4.

You can also use sn0wbreeze 2.8b8 to cook a custom pre-jailbroken firmware for iOS 5 GM which can be upgraded to without developers account using iTunes 10.5 beta 7.

  • Kastalarial

    jailbreak is different from unlock… if you are using a non legit sim then you are in semi deep shit, use a gevey if you have an ATT phone

  • Kastalarial

    I’m using Iphone 4 (GSM) and after jailbreak with  redsn0w 0.9.9b4 , the Cydia icon appears to be white color. Cydia cannot open as well as Safari. Please advise.

    Open RedSn0w and click “just boot”, follow instructions on screen. This is a tethered jailbreak, that means you will have to do this everytime your phone reboots or battery dies.

  • dearinsanity

    If you have the official IOS 5, and want to jailbreak using 0.9.9b4 instead of the new redsn0w 0.9.9b5, (because that version is not yet out for Windows) will you still have all of the IOS 5 features?

  • Justinball27

    It’s says most apple apps will not work like iBook and some others but I don’t use most the only thing I making sure I don’t mess up is the network with AT&T which I pay alot for and need! Can’t mess that up jaja anyone have any ideas or do I wait for the newer version of redsn0w for windows to not have to select the extra option?

  • dearinsanity

    I hate always having to wait for windows links to be posted. >.<
