Jailbreakers rejoice! RedsnOw 0.9.6rc9 has been released for RedsnOw 0.9.6rc9 is an untethered jailbreak for the 4.3.1 FW. The iDevices supported are the iPhone 4, 3GS, iPad 1 (sadly no support for iPad 2 yet) Apple TV 2G and iPod touch 4G.

Before you start: If your iPhone relies on a carrier unlock DO NOT PROCEED because ultrasnOw has not been updated for FW 4.3.1 yet. Please standby until it is released.
Now on to the fun stuff…
Step 1: Download RedSnOw and extract to your desktop. Then, download the firmware that corresponds to your device.
iPhone 4(GSM only)
iPad(1st gen)
iPod iTouch (4th gen)
Extract contents to your desktop
Step 2: Connect your iDevice to iTunes. Choose your iDevice on the left and hold down the “shift” button on your keyboard and click the “Restore” button on iTunes.
iTunes will ask you for the location of the firmware, choose the IPSW file you extracted on to your desktop.
Step 3: When iTunes has completed updating your iDevice to the firmware, go back to your desktop and fire up the redSnOw.exe application.
Step 4: After RedSnOw opens, click on the “Browse” button.
Step 5: Choose the 4.3.1 firmware IPSW on your desktop and hit “Open” button.
Step 6: Once the IPSW file has been verified by RedSnOw then hit “Next” button.
Step 7: RedSnOw will now prepare the jailbreak data.
Step 8: At the time RedSnOw finishes preparing the file then you can choose which option you would like. NOTE: Cydia needs to be installed so make sure that box is checked.
Step 9: Make sure your iDevice is turned off and connected to your computer then click “Next” button.
Step 10: Follow the steps that are provided by RedSnOw to put your iDevice into DFU mode.
1.Hold down both the Home button and the Power button for 10 seconds.
2.Without releaseing the Power button, also hold down the Home button for 5 seconds
3.Without releaseing the Home button, release the Power button BUT KEEP holding the Home button for 13 seconds.
Step 11: After your iDevice reboots, RedSnOw will start uploading the new RAM disk to the Kernel.
Step 12: Once the status bar is full, RedSnOw will notify that its “Done!” Click the finish button and allow your iDevice to reboot.
When your iDevice is finished rebooting, it will be fully jailbroken with Cydia to start you off.
All thanks to the Dev-Team for development of another fine jailbreak. Also, hand clap to Stefen “IOn1c” for providing the exploit.









I have read and re-read this material several times, and after item #1, you lost me. And I have been a geek since ’75! How about EXPLAINING what these files are! ISPW? DFU mode? etc. All I can do is look at the info and say WTF!
Tom: ISPW stands for iPod Software – it is the firmware file for your iOS device. You can think of it like the install CD for an operating system. The latest firmware files should be here: http://www.iclarified.com/entry/index.php?enid=750
DFU mode is a deeper version of recovery mode that bypasses a built in protocol called iBoot. It is built into all iOS devices and most jailbreak solutions require you to start from DFU mode.
Just download redsn0w and it will walk you through everything (with the exception of obtaining your ISPW which I outlined above)
IPSW is the firmware you need to update your iDevice, you can download it from various places on the net .. DFU mode is a series of holding the power button and home button for a certain number of seconds to make the screen go black and into what they call DFU mode, similar to recovery mode .. Just follow the instructions on the Redsnow software, it really is very simple and explains everything while you Jailbreak.
IPSW is the firmware that is provided below the redsnow link above. DFU mode is a state that you can put your iPhone into where it can interface with iTunes but does not load the iPhone operating system or boot loader. DFU stands for Device Firmware Update.
Hope this helps
Thanks for the info. I would have NEVER gotten ISPW frmo iPod Software – maybe if it was iPSW I would have figued that out.
I used a jailbreak (I forget, puts a skull-apple on my startup screen) that was so simple – I guess I will wait and see what else is coming down the pike. This seems to clumsy and dangerous to the phone, and I don’t want a $500 brick! (smile!0
Again, thanks!
I downloaded iPhone3,1_4.3.1_8G4_Restore.zip from the iPhone 4 link and extracted it on the desktop but there is no IPSW file in it?? There are many other files but no IPSW to point to in iTunes restore. What did I do wrong?
POLO!
I fihured it out. There’s no need to extract the IOS files. These were changed to .zip by the browser so just needed to rename it to .ipsw, that’s it.
You might wanna include this in your guide above!
i’ve tried going thru this over and over.. it always stops at UPLOADING RAMDISK on the computer screen and DOWNLOADING JAILBREAK DATA on the Iphone screen. I have IPhone 3GS 3.1.2, which i upgraded to 4.3.1,.. What do i do next? Please help. Thanks.
does this work on 4.2.1 iphone?
Very interesting article! DFU mode is a deeper version of recovery mode that bypasses a built in protocol called iBoot. It is built into all iOS devices and most jailbreak solutions require you to start from DFU mode. Just download redsn0w and it will walk you through everything
