Boot Your Tethered Jailbroken iPhone/iPod Touch iOS 4.2.1 [Windows] & [MAC]

The iPhone DevTeam 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”.

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 iPod touch 2G and iPhone 3GS
  • -b to specify your own boot logo png
This is surely something new for most users, and the process can easily scare you at a first look, but we assure you it’s a piece of cake. So let’s see how to boot your tethered jailbroken iPhone running iOS 4.2.1

Windows

HOW TO: Boot Your Tethered Jailbroken iPhone Running iOS 4.2.1
1. Download redsn0w 0.9.6rc7 and the firmware for your device on the desktop
2. Click on Start and search for ‘cmd’
cmd HOW TO: Boot Your Tethered Jailbroken iPhone/iPod Touch Running iOS 4.2.1 [Windows]
3. Now you will have to type:
%homepath%\Desktop\redsn0w_win_0.9.6rc7b\redsn0w.exe -j -i %homepath%\Desktop\iPhone1,2_4.2.1_8C148_Restore.ipsw
NOTE: change the filename of the .ipsw you are using to the .ipsw you downloaded for your device
NOTE: for iPod Touch 2G and iPhone 3Gs with old bootroom input the following command line:
%homepath%\Desktop\redsn0w_win_0.9.6rc7b\redsn0w.exe -j -o -i %homepath%\Desktop\iPhone1,2_4.2.1_8C148_Restore.ipsw
NOTE: To add bootlogos to your device you need to input the following command line:
%homepath%\Desktop\redsn0w_win_0.9.6rc7b\redsn0w.exe -j -o -i %homepath%\Desktop\iPhone1,2_4.2.1_8C148_Restore.ipsw -b %homepath%\Desktop\image.png  ( assuming that your custom boot logo is located on desktop )
NOTE: make sure you read what every argument means before applying them on your device. For example ‘-o’ is just for old-bootrom iPod touch 2G and iPhone 3GS. Do not input that argument on any other device, or you will get stuck in a boot loop. The commands above are just an example, and not meant to be copy-pasted. They are not universal.

3. In the terminal shell, type:
open /Users/murdaFSM/Desktop/redsn0w_mac_0.9.6rc7/redsn0w.app –args -j -i /Users/murdaFSM/Desktop/iPhone1,2_4.2.1_8C148_Restore.ipsw
NOTE: change the filename of the .ipsw you are using to the .ipsw you downloaded for your device

NOTE: The easiest way to make sure you got the right path to redsn0w.app and the .ipsw file is to drag and drop into the terminal shell the files. For example:

NOTE: please remember to change the permissions of your custom *.command files to allow execution
