The iPhone Dev Team has rolled out an update for redsn0w 0.9.6, the jailbreak tool that brought tethered/untethered jailbreak for iOS 4.2.1. If you happen to be the member of the tethered jailbreak, you will know how annoying is to boot into tethered mode every time. Well, the hackers gang have decided to make the tethered jailbreak a bit less painful by rolling out redsn0w 0.9.6rc7, whichr bring one-click tethered boot for the latest generation of iDevices.

iOS 4.2.1 untethered jailbreak

Here’s how the Dev Team made the announcement:

We’ve updated redsn0w to include “one-click” support for those of you running the tethered 4.2.1 jailbreak. Using command-line arguments, you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now”.

You will be required to use command-line arguments to get yourself a one click tethered boot

The available command line arguments are:

-j to ask redsn0w to “Just boot now”

-i <filename> to specify your reference IPSW

-o for old-bootrom iPod touch 2G and iPhone 3GS

-b <filename> to specify your own boot logo png

Here’s an example of how you can get the one click thing working on a Mac OS X machine:

For example, to get redsn0w for Mac to do a tethered boot of an iPod touch 4G jailbroken at 4.2.1: open ~/Desktop/redsn0w.app –args -j -i ~/Desktop/iPod4,1_4.2.1_8C148_Restore.ipsw This assumes both redsn0w and the IPSW are on your OS X desktop, so modify as necessary!

Note:

  • Included in the zip is an example script file that you can double click on to launch redsn0w like this (the Windows example assumes everything is in C:\). (Mac users: please remember to change the permissions of your custom *.command files to allow execution.)
  • PLEASE UPGRADE TO iTunes 10.1 FOR BEST RESULTS
  • WINDOWS 7 USERS SHOULD RUN redsn0w IN “XP COMPATIBILITY” MODE
  • Make sure you’re using a USB 2.0 port
