TheDev-Team has updated to easily boot devices that are running a tethered .
We’ve updated redsn0w to include “one-click” support for those of you running the tethered 4.2.1. Using command-line arguments, you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now”.
The available command line arguments are:
-j to ask redsn0w to “Just boot now tethered for now”
-i to specify your reference IPSW
-o for old-bootrom 2G and
-b to specify your own boot logo png
For example, redsn0w forto do a tethered boot of an 4G jailbroken at 4.2.1:
open ~/Desktop/redsn0w.app —args -j ~/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:). (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)!
● 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
