How to Jailbreak Your iPhone 4 Using RedSn0w (Windows) [5.0]

Posted October 18, 2011 at 7:51am by iClarified
These are instructions on how to jailbreak your iPhone 4 on the 5.0 firmware 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 wait until we have posted a Windows tutorial on how to update to iOS 5 using a custom ipsw if you need an unlock. The jailbreak is also tethered which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent 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 RedSn0w 0.9.9b6 from here and place it in the Pwnage folder. Likewise, download the 5.0 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0 firmware if you are already on iOS 5.0)

Extract the RedSn0w zip file by double clicking it.

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.

Step Four
Once RedSn0w opens click the Jailbreak button

Hi there, I am jailbroken with iOS 4.3 with iPhone 4. Can I update to iOS 5.0 somehow and jailbreak with redsnow? I tried to update to iOS 5.0 in iTunes but recieved error 3194. Let me know how I should proceed. Thanks in advance.
DuBCaDiLLaC - November 15, 2011 at 9:15pm
Apple is no longer signing 5.0 ipsw's. You would have to go to 5.0.1 and use Redsnow from there. Just remember, if you need an unlock that updating will upgrade your baseband.
dylan - November 21, 2011 at 4:33am
hi there...if jailbreak 5.0.1 can we still use back RedSn0w 0.9.9b6 (Windows): redsn0w_win_0.9.9b6.zip? or we should use RedSn0w 0.9.9b8 (Windows): redsn0w_win_0.9.9b8.zip? hope anyone will reply and advise on this. great thx
macuser007 - November 21, 2011 at 9:43am
is jailbreak worth it
dylan - November 21, 2011 at 9:53am
yes it is :)
jones - November 8, 2011 at 4:26am
hi, i did this jailbreak and after that my baseband changed to 04.11.08, so i was getting a NO SERVICE message after the jailbreak to 5.0 I had to undo it and go to the official 5.0 Ios so now i can make calls again, but it's impossible to downgrade the baseband !!! so i hope there will be a new jailbreak soon that works with the new baseband.. This thread does not work ! unless someone has a solution???
lilsizzo - November 8, 2011 at 2:23am
guys can anyone verify that it is still possible to add new contacts after having a tethered jailbreak? It seems to me that i couldnt and there is no other place where someone is like me ....facing this stupid issue...
mrk66 - November 6, 2011 at 5:42pm
Hi! I don't want to nag or anything but why has no one come up with an untethered jailbreak and why is it so difficult to enable an unlock for that jailbreak? I am very grateful for all the hard work the iPhone dev team puts in the jailbreak process. I am just curious of what the obstacles are. I also know that apple is doing their best to stop jailbreaking but still anything man made can be hacked right? where is Geohot when you need him. ;)
lilsizzo - November 5, 2011 at 4:10am
is it just me or i could not add new contacts.
joe - October 30, 2011 at 6:06pm
can any one help me i have jailbreak my iphone 4 to ios 5 and all ok but if i trun my phone off when comes back on it stays stuck in the apple help
mrk66 - November 6, 2011 at 5:33pm
Hi, The only jailbreak right available is a tethered one which means, everytime you turn you iPhone of or if you run out of battery, you have to connect your iPhone to a computer and run RedSn0w again in order to ge your iPhone up and running.

Tara - October 22, 2011 at 3:43pm
I had IP-4 firmware 4.3.5 and baseband 04.10.01. I updated to iOS 5 using Sn0wbreeze on my PC (with windows-7). I surely updatede to iOS 5 and preserved my baseband (04.10.01) to unlock using Gevey. It works or you can wait for Redsow. Instructions are below in the link. http://www.howtoarena.com/preserve-baseband-jailbreak-ios-5-with-sn0wbreeze-on-windows/ Be happy and enjoy.

When I'm running redsnow to jailbreak, the process freezes at 'Eploiting with limerain' step! Does any one have a solution for this?

My Iphone 4 was jail broken w/ cydia and i think unlocked (not sure). It used to be on ATT i use tmobile. Now it's stuck on apple logo and won't turn off. Before when i could turn it off, i had to force it and it would reboot with the pineapple, but it never recognized my sim card. i don't know what to do i'm without a phone. Any help would be grateful!
jas - October 19, 2011 at 10:04am

Joe - October 19, 2011 at 12:40pm
Did it come on and what did u have to do joe
jas - October 20, 2011 at 12:28am
i redo all the step. now able to restart, but the cydia not functioning.. is anyone experiencing this problem?
Joe - October 19, 2011 at 6:49am
Hi is it all working ok? Can I get the iPhone off when I want
TOCS88 - October 19, 2011 at 12:35am
Hmmm, still not seeing an option to use Tiny Umbrella to preserve my 1.59 Baseband on my iphone 4. Is there a way to get to iOS and keep 1.59? Anybody? Thanks
Freddyd13 - October 20, 2011 at 1:49pm
Yup just use redsnow or snowbreeze to create a custom firmware that wont update your bb. Ultrasnow has been update to support ios5 with old bb
ufgators1996 - October 18, 2011 at 2:08pm
If I used Sn0wbreeze to create my custom ipsw to preserve my bandwidth, can I use this version of redsn0w to jailbreak my iphone 4?
TOCS88 - October 19, 2011 at 10:12pm
I'm afraid once you make the custom IPSW with snowbreeze, Redsnow cannot load it. I have tried a few times. :(
