As promised, redsn0w has been updated to include “one-click” support for all those who are currently running the tethered iOS 4.2.1 jailbreak. Using command-line arguments, you can now bypass the screens you would normally see as you use redsn0w to “Just boot tethered for now”. Follow the instructions below on how to untether your iPhone, iPod Touch and iPad in a single click.
The available command line arguments are:
-j to ask redsn0w to “Just boot now tethered for now”
to specify your reference IPSW
-o for old-bootrom iPod touch 2G and iPhone 3GS
to specify your own boot logo pngFor 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! 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.)
This should help ease the pain of the tethered jailbreak until @comex comes up with a 4.2.1 untether (or for those of you with legit access to the 4.2b3 IPSW, until the “Jailbreak Monte” untether is out of beta)!
- Make sure you upgrade to iTunes 10.1 for best results
- Windows 7 should run redsn0w IN “XP Compatibility Mode”
- Make sure you’re using a USB 2.0 port
