How to Jailbreak iOS 5.1.1 with RedSn0w

You can jailbreak iOS 5.1.1 untethered using RedSn0w 0.9.12b2 on iPhone, iPad and iPod Touch. These are the steps to jailbreak iPhone 4S, iPhone 4, 3GS, iPad 3, iPad 2, iPad 1, iPod Touch 4G/3G iOS 5.1.1 untethered with RedSn0w 0.9.12b2…

RedSn0w supports all iOS 5.1.1 compatible devices:

  • A5 devices: iPhone 4S, the new iPad 3, iPad 2
  • A4 or older devices:  iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G, iPad 1

RedSn0w 0.9.12b2 contains the same Rocky Racoon exploit used in Absinthe 2. This version of RedSn0w offers two methods of jailbreak:

  1. Backup/Restore Method (Applies to A5, A4 and older devices)
    This method is pretty much similar to Absinthe jailbreak. you just need to connect your iPhone, iPad or iPod Touch and hit the jailbreak button on RedSn0w.
    Your iDevice MUST BE activated (NOT stuck on Connect to iTunes).
    There is no need to put your iDevice into DFU Mode.
  2. DFU RAM Disk Method (Applies to A4 or older devices only)
    DFU RAM disk method is preffered method if you have many songs, videos and other media on the device.
    It requires you to enter DFU Mode manually (RedSn0w will guide you!).
    This method is mandatory if your iPhone is inactivated.

Let’s jailbreak your iPhone, iPad and iPod Touch using both methods on iOS 5.1.1.

How to Jailbreak iOS 5.1.1 with RedSn0w

iPhoneHeat May 8, 2012, 7:32 pm

Use custom firmware created with RedSn0w.. read the guide first, there’s a link for creating custom firmware… STAY AWAY FROM OFFICIAL FIRMWARE or you’ll lose your unlock

iPhoneHeat May 9, 2012, 6:19 pm

RedSn0w > Extras > Select IPSW … browse and select iOS 5.1 first..
Then put your iDevice into PWNED DFU Mode (RedSn0w > Extras > Pwned DFU)

mustafa May 9, 2012, 10:58 pm

you do not understand me my iphone 4 has 5.1.0 now

iPhoneHeat May 10, 2012, 7:23 pm

Create a custom iOS 5.1.1.. n (there’s a link in the guide on how to create it) then follow the instructions from my previous comment..
after putting your iDevice into PWNED DFU mode, restore via iTunes using the *CUSTOM* iOS 5.1.1 (NOT STOCK)

miggykloude May 11, 2012, 10:15 am

I tried to update a 3Gs JB 4.3.3 BB 6.15.00 and it doesn`t work ! I cannot make an IPSW with redsn0w without Error: Unsupported IPSW !
Can anyone help me to update my Phone ????

tomithy5 August 1, 2012, 8:59 am

what i did is change the file type to an ipsw and make sure you have the latest version of red sn0w

traxxex8 June 26, 2012, 10:13 pm

i got a iPhone 3Gs , iOS 5.1, BB 06.15.00, i think it’s a new bootrom (xx008xx…)

i jailbroke it and installed the iPad baseband before the 5.1.1 untethered jailbreak came out.
so now i want to update my iphone to 5.1.1 so i can have a untethered jailbreak
but i am afraid that i will brick my phone
some say that i need to prevent the baseband upgrade, some say that i need to downgrade before updating
can i update via iTunes wit the original IPSW or do i need a custom one? can the iPad BB on my iPhone get updated?
i need help!

George July 6, 2012, 2:38 pm

something is missing in the explanation i guess……

Ankit @ iLifeGeeks July 20, 2012, 12:41 pm

Abstrine is the easiest way jailbroke in just five minutes and one click

tomithy5 August 1, 2012, 8:54 am

tomithy5 August 1, 2012, 9:12 am

tle112 September 21, 2012, 11:43 pm

Hi so when i try putting my phone is DFU mode it says unrecognized build.

puneet January 2, 2013, 1:12 pm

I want to update my iphone 3GS 4.0 to unthered 5.1.1, and then i want to jailbreak and unlock.
My question is that do I need to create custome firmware ios 5.1.1 using red snow and then update using itunes or just restore the original ipsw file using itunes.
Also do I need to take care of baseband.

macbeth December 6, 2013, 7:21 am
