    How to use Redsn0w 0.9.7 to Untethered Jailbreak


    Redsn0w 0.9.7 beta 1 for Mac OS X was released. It can Jailbreak iOS 4.2.1 on devices such as iPhone 4, iPod Touch 4G and iPad. Following is the post which will help you on How to Untethered Jailbreak using Redsn0w 0.9.7

    The backup procedure with redsn0w 0.9.7 b1 isn’t easy. I advice you to be very careful when jailbreaking using Redsn0w 0.9.7

    Also follow the below points before Jailbreaking using Redsn0w 0.9.7

    • This is a beta tester program. It’s not a general release! Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
    • For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
    • Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
    • This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
    • Cydia must have your 4.2b3 SHSH blobs saved on file. (As we approach a general release, we’ll provide a way to let you use locally saved hashes too).
    • You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too). The correct invocation of the relay is just as that page says: “./tcprelay.py -t 22:2222”. If the relay isn’t installed or running correctly by the time the redsn0w ramdisk has started, you’ll need to restore to stock FW again to try it again. Please test it beforehand to save yourself some time!
