  • iPod Touch 4G, iPod Touch 3G
  • iPad 1


If you’ve already updated to iOS 5.0.1 + tether jailbroken your iPhone, iPad or iPod Touch, the only thing you need to get Untethered jailbreak is to install ‘Corona 5.0.1 untether’ from Cydia.

Here’s how to: jailbreak iOS 5.0.1 Untethered using “Corona 5.0.1 Untether” jailbreak tweak.

How to Jailbreak iOS 5.0.1 Untethered with RedSn0w


Download iOS 5.0.1
Download RedSn0w 0.9.10b1

Step 1

First of all connect your iPhone, iPad or iPod Touch and backup your personal data before restoring to iOS 5.0.1.

Attention iPhone Unlockers

UltraSn0w or Gevey SIM dependant iPhone users need to preserve their baseband before updating to iOS 5.0.1. You can do that by creating a custom firmware with RedSn0w. Here’s how to do it:

How to: create custom firmware with RedSn0w

*** iPhone unlock dependant users MUST always use custom firmware instead of Stock iOS firmware

Step 2

Connect your iPhone/iPod Touch/iPad to iTunes 10.5 or later, hold down the Shift (Windows) or Alt/Option (Mac) key and hit the restore button on iTunes and then browse select the downloaded iOS 5.0.1 IPSW file (Unlockers MUST use Custom Firmware).

Step 3

Once the restore process is completed;
Run RedSn0w;
Select Jailbreak;
Then check “Install Cydia” and hit the next button.

Step 4

Now make sure your iPhone, iPad or iPod Touch is turned OFF and Plugged in to your computer. Hit Next.

Step 5

Now follow the on-screen instructions to enter your device in DFU mode.

  1. Hold Down The Power (Corner) button for 3 Seconds
  2. Without releasing the Power button, also hold down the Home (Bottom Center) button for 10 seconds
  3. Without releasing the Home button, release the Power button BUT KEEP holding the Home button for 15 seconds

As soon as your iDevice enters DFU Mode, RedSn0w will start jailbreaking it, which should be completed within few minutes. That’s it!

Enjoy iOS 5.0.1 untethered jailbreak on your iPhone, ipad or iPod Touch.

dennisck December 28, 2011, 5:23 am

I lost the telco carrier connection after jailbreak. Anyone know what is the problem?

Romario December 28, 2011, 6:46 pm

If your iphone is SU ( Not Factory Unlocked ), You need to install ultraSn0w from Cydia to unlocked your carrier

Doba December 29, 2011, 5:04 pm

Reboot your phone after ultrasn0w installs as well.

tarin457 December 28, 2011, 5:34 am

ololoo December 28, 2011, 6:27 am

after restoring and jailbreaking how do i activate my iphone 3gs.tried activating with redsnow but doesn’t seem to work any ideas?Pls Help!!

iPhoneHeat December 28, 2011, 3:25 pm

From RedSn0w… Jailbreak >> selecting Cydia (make sure “Deactivate” option is NOT selected) should hacktivate your iphone

ololoo December 28, 2011, 9:10 pm

Thanks it worked!….but i have installed ultrasnow but it doesnt unlock the phone i get no service,what is wrong?

iPhoneHeat December 29, 2011, 1:23 am

your baseband?

tomas January 2, 2012, 2:11 am


rebelhank007 December 28, 2011, 9:25 am

which basebands of iphone4 and 3gs does this untethered jailbrake support?

iPhoneHeat December 28, 2011, 3:22 pm

jailbreak and baseband are two unrelated things.. Unlock depends on baseband.

rebelhank007 December 28, 2011, 4:44 pm

k then after jailbreaking ,,
can i unlock my 3gs (using ultrasnow) and
iphone 4(using gevey sim) as usual?
or else ultrasnow works for both??

Kayilly December 28, 2011, 10:11 am

I downloaded the jailbreak for iOS 5.0.1 and now winterboard doesnt work and i cant download anything. Help please!

Kayilly December 28, 2011, 11:04 am

Cannot comply msg.

iPhoneHeat December 28, 2011, 3:23 pm

Cydia Repos are being hammered.. so be patient.. and make sure to check if Winterboard is compatible with 5.0.1

ihdarr December 28, 2011, 5:53 pm

how do we check it

youness December 28, 2011, 10:55 am

It seems like hackactivation(de-activate) not working,Im stuck again in activation(welcome)step.
I did jailbreak then deactivate….but it wont pass the welcome page…..any solution.

chkenwing January 25, 2012, 12:41 am

I’ve been getting the same problem.

I’ve tried all sorts, custom firmware, straight jailbreaking, doing the emergency call technique but nothing seems to work.

I’m on a 3GS with bb 6.15 running 5.0.1.

Bastige thing won’t budge!

snake December 28, 2011, 11:13 am

guys i tried it yesterday its working BUT it contains minor bugs would not make you comfortable

bugs like u will have problem and arranging ur icons ir move them in/out folders

Steve December 28, 2011, 11:32 am

I’m not sure why but every time I try to restore with a custom firmware, I get an error 1604. Does anyone know how to fix this?

jose January 18, 2012, 2:18 am

are you sure you are in DFU mode? use ultrasnow extra option “enter PWned dFU mode” previously to try to restore.

jose January 18, 2012, 2:19 am

I meant redsnow extra option.

john December 28, 2011, 12:27 pm

iPhoneHeat December 28, 2011, 5:00 pm

server over loaded…

jacob December 28, 2011, 6:27 pm

so how can i do? just waiting?

iBarf December 28, 2011, 10:58 pm

Yep. It fucking sucks, but obviously Cydia is not the AppStore backed up by a multimillionaire company, so we can only wait for it to work (Although Cydia is kinda slow most of the time anyway).

jacob December 29, 2011, 4:39 am

thanks man! 😀

Predictabl3 December 28, 2011, 4:59 pm

every things seems ok but is there any problem with cydia?
cos it takes a very long time to add a sources and it keeps faile sometimes. any 1 with this problem?

to ios 5.0.1 ? i depends on Ultrasnow Unlock ? please Asure me can i Can i Can i ?

Doba December 29, 2011, 5:09 pm

You can. Download 5.0.1 from the links here on the site. DL redsn0w and go to the Extras button on the program. Use custom firmware option. Update phone in iTunes using NO_BB firmware created by resn0w. Jailbreak with redsn0w and install ultrasn0w. Reboot and enjoy.

Shahrukh December 30, 2011, 10:31 am


wydchr December 29, 2011, 6:57 pm

I created a custom firmware as I need preserve the baseband to unlock but after installing the custom firmware and then trying to jailbreak redsn0w produces this error dialogue: ‘The IPSW for the following build is needed: iPhone2,1_5.0.1_9A404 The required IPSW is either not public or not available right now. PLease provide it manually using “Extras->SelectIPSW”. Note: If you provide this IPSW once, it will be cached so you don’t need to provide it again.’
Redsn0w does not proceed after this message pops up, any help with this will be much appreciated. I have a iPhone 3GS by the way.


chinatzu December 30, 2011, 5:19 am

hello i also have problem with ibooks, it crashes when i try to open it. Does anybody know a solution?

Romario December 31, 2011, 6:06 pm

Just delete it and install iBooks fix from Cydia

Badassbd December 31, 2011, 4:46 am

I have gone over the steps continuously and still cannot get my iPhone 4 Verizon into DFU mode. I get through the first and second countdowns but when I just hold the home button on the third countdown it gets down to 9 secs and then it goes through two steps and then stops at waiting to reboot. My phone reboots back to normal. Nothing else. I am trying this on a pc, have tried all 3 versions of redsnow, disabled security …help!

Badassbd December 31, 2011, 4:49 am

I have tried all of my USB ports as well.

Gugi December 31, 2011, 8:46 pm

rishab155 January 2, 2012, 12:56 pm

if i create a 5.0.1 custom firmware for my iphone 3gs with baseband …and then restore it to the custom firmware ..and jailbreak using redsn0w …will it surely hacktivate my iphone ???
i rely on hacktivation …as i do not have an official SIM !

dingleberry221 January 2, 2012, 9:59 pm

my verizon iphone wont go into dfu mode and when im trying to jailbreak it says waiting for reboot, what should i do?

Dave January 8, 2012, 6:50 am

Tried to update my iPhone 4 and iPad 1 to 5.0.1 from 4.3.1. Ran the update/jailbreak (used redsnow) and it seems like the update went ok…

However, after it did the jailbreak when it goes to reboot the device, both my iPad and iPhone do the same thing. The apple logo appears, sits for about 1 min, then recycles and repeats. Can’t get either device to boot up and I have no idea why it’s doing that… anyone have an idea and/or suggestion? Thanks

kyoko January 8, 2012, 8:53 pm

Can I use RedSn0w to creat a custom IPSW for my 3GS-baseband 06.15.00? What does “If you’re creating a custom firmware for your iPhone 3GS, RedSn0w will warn you about iPad Baseband patch” mean?

kevin January 9, 2012, 12:50 pm

Mine is 3gs old bootroom version 4.1 baseband 6.15 I update to 5.01 and using rednow to unlock and jailbreak then ran into problem that it could not read the sim stay at searching ,any one have this problem and already have a solution, Please help
