These are instructions on how to jailbreak your iPhone 4 on the 5.1.1 firmware using RedSn0w for Windows. The Mac version of this tutorial is here.

Upgrading your iPhone to iOS 5.1.1 through iTunes will update your baseband, potential removing or ruining your chances for an unlock. Please follow this tutorial on how to update to iOS 5.1.1 using a custom ipsw if you need an unlock. Remember to save your SHSH Blobs by following this tutorial before continuing.

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 5.1.1 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.1.1 firmware if you are already on iOS 5.1.1)

Extract the RedSn0w zip file by double clicking it.

I have an iPhone 4 factory unlocked (can work with any sim card or phone company that I want). I think it originally came with iOS 4.3.3 and I already updated the iOS and jailbreak many times. Nowadays I have it with iOS 5.0.1 already jailbroken.. I'd really like to update to iOS 5.1.1 and jailbreak it. My question: If this iOS update and unthetered jailbreak to 5.1.1 still possible at the moment? or I will end up with a "blocked" iphone, because of the erros in the process, with no other choice that updating to iOS 6.0.1 (current official) with no jailbreak at all. Hope it understands what I'm asking.. Please, someone answer.. Thanks!

Now apple close the sign off on 5.1.1 and if I am on JB iOS 4.1, how to upgrade to JB 5.11? new to JB thx alot
jack - December 16, 2012 at 4:35pm
If you saved your blobs or they available just use the jailbreak program to install your IOS and then jailbreak from there. I personally use iFaith and Tinyumbrella to do it, long winded I know but old habits die hard.
tcr - September 22, 2012 at 8:08pm
i just tried today moving from 4.3.3 to 5.1.1 but apparently apple has stopped signing 5.1.1 , i tried everything , with editing hosts file and adding with original 5.1.1 on desctop and laptop both 1600 error , tried with tiny umbrella again 1600 error . Tried cleaning hosts file i get 3194 cos appla stopped signing 5.1.1 . I tried stiching and restoring , everytime i restore i restore in DFU , and i got stuck in a restore loop which was only able to be fixed by using the clean restore from itunes ( clean hosts ) to 6.0 how can i restore to 5.1.1 because i need cydia !
Manuka - September 27, 2012 at 2:25am
I'm getting the same issue as you man. Need to upgrade to 5.1.1 and I keep on getting a 3194 error.
kdv - September 27, 2012 at 6:22am
i got stuck with this error too.. need help sir.. thanks
muerto - September 27, 2012 at 3:22pm
have you been able to find the solution if so please post it as also need to update my phone. cheers
tcr - September 30, 2012 at 9:29am
Found the solution : after u get -1 error from what i described above , and get stuck in restore . What worked for me is redsn0w-> then extras(or more) -> recovery fix . It tells u to turn off ur phone so u can click next for the next steps to enter DFU , but thats impossible , the power button turns off ur phone for 3-4 seconds so what u need to do is just HOLD BOTH POWER AND HOME for about 10 seconds , the screen will go black , then after 10 seconds release the power button .. and couple of seconds later , text , bootloader loading on the iphone appears , then leave ur phone do the rest . THen u can freely jailbreak
kdv - September 30, 2012 at 4:04pm
still doesn't work for me.. error 3194.. btw, im using new BR.. thanks
