These are instructions on how to perform an untethered jailbreak of your iPhone 4 on 5.0.1 using RedSn0w for Windows. The Mac version of this tutorial is here.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please follow a Windows tutorial on how to update to iOS 5.0.1 using a custom ipsw if you need an unlock.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the 5.0.1 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0.1 firmware if you are already on iOS 5.0.1)

Extract the RedSn0w zip file by double clicking it.

How to Perform an Untethered Jailbreak of Your iPhone 4 (Windows) [5.0.1]

Step Two: (You can skip this step if iOS 5 is already installed on your device)
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down Shift and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the 5.0 firmware ipsw. Click the Choose button to continue.

iTunes will now update your iPhone to the new firmware.

Step Three
Launch the redsn0w application from the redsn0w folder we extracted earlier.

**Windows 7 users may want to try running the redsn0w executable mode as an administrator in Windows Vista compatibility. You can do this by right clicking the executable and selecting Properties from the contextual menu.

Step Four
Once RedSn0w opens click the Jailbreak button

Step Five
Plug your iPhone into the computer and make sure its OFF then click the Next button

Step Six
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Seven
Your iPhone will now reboot

Step Eight
RedSn0w will now prepare the jailbreak data.

Step Nine
Select Cydia from the list of options and click Next.

Step Ten
Your iPhone will now be rebooted again and RedSn0w will begin uploading the new RAM Disk and Kernel.

Step Eleven
Once this is complete you will be notified that RedSn0w is done. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

*As usual a big thanks to the iPhone Dev-Team, Pod2g, and Geohot for their hard work and contribution to the iPhone community.

I am going to upgrade iPhone 4 (GSM) currently running iOS 4.3.3 (jailbroke) with modem firmware 4.10.01. I don't need to unlock. Can I simply Restore in iTunes or do I need to Shift+Restore using the firmware found on this site?

Tubagznyven - March 14, 2012 at 9:06am

Shift restore

Hi all, i had an iphone 4 baseband: 2.10.04, Itune v 10.5.2. I'd like to upgrade 5.0.1 and follow this tutorial by; downloaded redsn0w_win_0.9.10b3 and iPhone3_3_5.0.1_9A405_Restore.ipsw. Then i had problem with the first step when i try to "restore iPhone3_3_5.0.1_9A405_Restore.ipsw" with Itune, it's said "this firmware is not compatible". Could anyone help me to solve this out? Appreciate for the next reply.

Amine - February 2, 2012 at 12:16pm

Hi, Check if your i phone is CDMA or GSM. You have to download the correct version of the the fimware according to this.

yayako - February 2, 2012 at 5:09pm

the firmware that i download is for GSM, which is suitable for mind. Please recommend for the right one. I will appreciate for your next reply.

Amine - February 3, 2012 at 7:18pm

Hi, I think that you had download the cdma firmware (according to your first post). You can download the GSM firmware in the link below: http://appldnld.apple.com/iPhone4/041-3309.20111109.64rtg/iPhone3,1_5.0.1_9A405_Restore.ipsw

ahmed - March 13, 2012 at 6:51pm

my computer dosent seemto read when the phone is on dfu mode im sure im doing it right but then nothing happens it tells me to look on google or youtube to find out how to put my phone on dfu mode any suggestions???

tubagznyven - January 10, 2012 at 10:11am

If u think it's right,just try again then maybe your timing for entering dfu mode just incorrect

Coose - January 28, 2012 at 6:02pm

Same for me. It does go to DFU, but the PC needs to re-identify the USB device. wait for windows to finish and then do a back, next. Redsn0w will see the DFU mode and do its thing

Tubagznyven - January 5, 2012 at 7:39am

Of course u can't,coz this jb for iphone 4

lucky005 - January 4, 2012 at 11:23am
