The necessary requirement for untethered jailbreak is that you have SHSH blobs for iOS 4.2 b3 saved on Cydia servers. So, if you didn’t save SHSH blobs or you have got one of old devices like iPhone 3G(S), iPod Touch 3G, you can use Redsn0w 0.9.6 rc7 to jailbreak the device and perform one-click tethered boot.
One Click tethered boot feature in Redsn0w 0.9.6RC7 allows you to skip almost all steps and you can get booted your device with single command or one click.
Here is the complete step by step how-to-do one-click tethered boot method:
For Windows Users:
Step 1: Download the Redsn0w 0.9.6 RC 1 zipped folder and extract it.
Step 2: Place Redsn0w.exe and iOS 4.2.1 IPSW file in one top-level folder just for convenience; as you can see I have placed these two files in the folder “jailbreak” on E drive.
Step 3: If you are a Windows 7/vista user, make it sure that you run Redsn0w in compatibility mode. For this purpose right-click on Redsn0w.exe file and click on “Properties”. Go to “Compatibility” tab and check these two options:
- Run this program in compatibility mode for:
- Run this program as an administrator
as shown in the screenshot below.
Step 4: Open the Command Prompt and run the following commands.
To select E: drive, type
e:
and press Enter.
To select jailbreak folder, type
cd jailbreak
and press Enter.
Now type the following command
redsn0w.exe -j -i “E:jailbreakiPhone2,1_4.2.1_8C148a_Restore.ipsw”
And hit Enter button. See the screenshot below:
The complete command will be like this:
E:jailbreakredsn0w.exe -j -i “E:jailbreakiPhone2,1_4.2.1_8C148a_Restore.ipsw”
The other available command line arguments for Redsn0w 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
Short-Cut and If You Are Not Familiar with Command Prompt:
If you don’t know how to use command prompt or you don’t want to type those commands on every boot, you can also create a short-cut file for this purpose.
To ease the procedure we will use the shortcut file “boot-ipt4g” which you find in the redsn0w folder downloaded in Step 1. Right click on it to open the properties.
Go to “Shortcut” tab and type the exact path of Redsn0w.exe and respective iOS 4.2.1 file in the field of “Target”. As we have already placed these two files in E:jailbreak folder, so we will use this:
E:jailbreakredsn0w.exe -j -i “E:jailbreakiPhone2,1_4.2.1_8C148a_Restore.ipsw”
Place type the correct file names and destination folders if you have changed the files names or placed these files in any other location.
Now go to “Compatibility” tab to run Redsn0w in compatibility mode. See the Step 3 for more details. You can also go to “General” tab and change the file name from “boot-ipt4g” to any name like “boot-iphone3gs” etc.
Apply the changes and save the file. Now double-click on this shortcut file to run the redsn0w without typing any commands.
For Mac Users:
To get the one-click tethered boot on Mac, type the following command, assuming that all the files are on desktop:
open ~/Desktop/redsn0w.app –args -j -i ~/Desktop/iPod4,1_4.2.1_8C148_Restore.ipsw
(Mac users: please remember to change the permissions of your custom *.command files to allow execution.)
For best results use the latest iTunes 10.1 version.

The iPhone DevTeam has just released an update to their redsn0w which allows us to untethered jailbreakiOS 4.3.1. The 4.3.1 untether exploit comes courtesy of Stefan Esser (@i0n1c on twitter), a security researcher based in Germany. Stefan has a long history of vulnerability research, and ironically his first contribution to theiPhone jailbreak community was improved security — last year he beat Apple to the punch and implemented ASLR for jailbroken iPhones with his “antid0te” framework.
The 4.3.1 untether works on all devices that actually support 4.3.1 except for the iPad2:
- iPhone3GS
- iPhone4 (GSM)
- iPod touch 3G
- iPod touch 4G
- iPad1
- AppleTV 2G (PwnageTool only for now)
The reason the untether won’t work as-is on the iPad2 is that it requires a bootrom or iBoot-level exploit toinstall, and the iPad2 is not susceptible to either the limera1n or SHAtter bootrom exploits.
WARNING WARNING — ultrasn0w users don’t update yet! We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w. And remember once we do fix ultrasn0w for 4.3.1 (we’ll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn! Don’t ever try to restore or update to a stock IPSW, or you’ll lose the unlock!
What you need:
- iOS 4.3.1
- redsn0w ( Mac or Windows )
HOW TO:
NOTE: the process is identical on both Mac OSX and Windows, and also identical with previous redsn0w releases. The images used in this tutorial are from previous redsn0w tutorial, so do not be alarmed.
1. Restore your device with a stock iOS 4.3.1 firmware. ( again, by doing this you will loose the ability to unlock!!!)
Redsn0w 0.9 4 Download For Mac
2. Run redsn0w, and click on browse. Browse for the stock iOS 4.3.1 and open it
3. Wait for redsn0w to recognize it and click ‘Next’
4. On the next screen select what you want to be installed on your iOS device(s). By default, Cydia and ‘enable battery percentage’ is selected. I suggest you deselect battery percentage and everything else, and just install Cydia. This will improve ( a bit ) the overall speed of your device – if you are on a iPhone 3G. If you choose to “Enable battery percentage”, you actually toggle that off and on via Settings->General->Usage.
IF you only need to restore with a custom firmware, deselect everything, and select only “Just enter pwned DFU mode right now”
5. redsn0w will ask you to turn your device off. If it’s not already off, plug it in FIRST and then turn it off. Click next to continue
6. Now, you will need to put your device in DFU mode. Follow the instructions on the screen.
7. Wait a few seconds for redsn0w to do its thing, and you are done. You can close redsn0w because everything else it’s happening directly on the device.
NOTE: Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub).
