iOS 4.3.3/4.2.8 jailbreak with sn0wbreez 2.7 Step by step Guide

**iphonehelper** · 05-07-2011, 03:25 PM

Sn0wbreeze 2.7 Supported devices include:

* iPhone 4 (GSM)
* iPhone 4, iOS 4.2.8 (Verizon)
* iPhone 3G
* IPad
* IPod touch 3G
* IPod touch 4G

Step 1: First, download all the required tools and files to your Windows desktop:

and install iTunes 10.2.2 for Windows.
sn0wbreeze 2.7 for Windows.
iOS 4.3.3 for iPhone, iPad or iPod touch.
iOS 4.2.8 for Verizon iPhone 4.

Step 2: Start Sn0wbreeze, click the next “blue” colored arrow to proceed.

Step 3: Select the required firmware .ipsw file (iOS 4.2.8 for Verizon iPhone 4, or iOS 4.3.3 for GSM iPhone, iPad & iPod touch) for your iOS device by clicking on the “Browse” button.

Step 4: Sn0wbreeze will now identify the selected IPSW file. Once done, click the next “blue” colored arrow to proceed.

Step 5: Now select the “Expert Mode”, followed by “Build IPSW” option to start creating your custom firmware.

Since building custom firmware may take some time, you can optionally play Pac-Man game to kill some time.

Step 6: Sn0wbreeze will greet you with the following “Done!” message when the custom firmware has been successfully created.

Step 7: Now follow the onscreen steps to enter DFU mode using Sn0wbreeze:

Hold Power and Home buttons for 10 seconds
Now release the Power button but continue holding the Home button for 10 more seconds
You device should now be in DFU mode

If you have followed the steps correctly, you will get the following message from Snw0breeze

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold Left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in iTunes and then release this button.
This will make iTunes prompt you to select the location for your custom firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch).

Is this tethered or untethered? I am on 4.2.7 I really want to wait till greenposiOn comes out. It just seems easier than RedsnOw. I am new to Jailbreaking. Untethered means you can reboot the phone without a computer, yes?

Yes, untethered means that you can reboot your iPhone and still use all of the jailbreak apps.

The redsn0w untethered jailbreak is no more difficult than greenp0ison. I'm no jailbreaking expert. All I do is follow the directions the fine people post here and it works. Even if you screw up the jailbreak, you always can bail out with the iTunes restore and start over. I goofed up the process and my phone was dead in the water but reconnected the usb, restarted iTunes, restored out of box and redid the jailbreak and worked perfectly fine. It''s practically foolproof.

I'm trying to upgrade from 4.2.6 to 4.2.8 and i'm getting the error message that says IPSW file is not valid. I've downloaded this file afew times and still can't do it. Again, Any assistance will greatly appreciated.

**mrwonka75** · 05-09-2011, 08:38 PM

I followed all the steps to JB 4.2.8. I went all the way to restore on iTunes but I don't have cydia anywhere on my phone. Not sure what went wrong can someone please point me in the right direction to get my JB going again? Or is it just as easy to go thru the whole process again? Thanks in advance.

Are you dragging the zip file into the window where it asks "drag the ipsw into me?"

Once it gets going, at some point, the actual .ipsw file will be created on the desktop which you will need later on during the jailbreak process.

Did you hold down the <SHIFT> key, then press restore, then select the .ipsw file for ios 4.2.8? or just press the restore on iTunes? If you just pressed the restore, you will only be restoring the phone back to factory, out of the box unjailbroken state. You must use the shift key when pressing the restore on itTunes.

**laurido92** · 05-09-2011, 09:37 PM

I finally got the file to work but when itunes tries to restore the phone I get an error 21 message iphone could not be restored.

**zwoof** · 05-09-2011, 10:03 PM

I don't quite know what the error 21 is but I had problems that caused my phone to be stuck in limbo so what I did was start from scratch. I reconnected the phone, iTunes opened up, detected the phone and did a clean install and just upgraded the firmware to 4.2.8 and made sure the phone worked properly.. Then I attempted the JB again and it worked error free. I don't know if i was having problems because I tried to JB to 4.2.8 from a jailbroken 4.2.6. I'm pretty sure it was supposed to work but when I got a restore failed, that's when I just started from scratch. I did get the error that deals with a line in the hosts file that threw me off which led me to start over. Maybe you could try starting over if that error 21 is a problem unless somebody knows why that error occurred and the fix.

Yea I did the left shift just like the step said and chose the .ipsw file. It went through the restore and told me I had like 29 things that weren't able to load??? Yes I am back to factory!! Can I just go through the steps again?? And do I have to download all the files and snowbreeze again?

I don't think that's necessary. Now that you got the device back to factory with the new 4.2.8 load, just try and run the JB again.

**tibbi64** · 05-10-2011, 11:32 AM

Here goes...downloading IPSW file now. Can't wait to be team jb!

**tibbi64** · 05-10-2011, 01:08 PM

Finally got it in DFU mode.

This is how I did it also, I still got some errors but I a limped my way through and it worked.

Alright!!That's great. Glad you got it going.

**AirAaron** · 05-10-2011, 09:02 PM

I have 4.2.7 jailbroken. Is it really worth updating to 4.2.8 and jail breaking again?

**Grafixx01#IM** · 05-11-2011, 08:58 AM

I think I jailbroke my VZW iPhone4 with 4.2.8 correctly. Now every time I go into iTunes it says there is an update from my carrier do I want to download and update the iPhone.

Can anyone tell me if they too are getting this? If you are or did, if you do the update, is the phone still JB?

**kemiyo** · 05-11-2011, 10:00 AM

First, thank you for the detailed instructions on how to Jailbreak iOS 4.2.8 with Sn0wbreeze 2.7. The Jailbreak itself went perfectly, but the Jailbreak seems to have some issues.

I first Jailbroke my Verizon iPhone 4 with iOS 4.2.6 using the Greenpois0n Jailbreak. It went flawlessly and I quick purchased MyWi, My Profiles and My3G. All three apps worked great and precisely as documented. But when I updated my phone with the Sn0wbreeze 2.7 Jailbreak for iOS 4.2.8 I found that MyWi will no longer run in infrastructure mode as a WiFi hotspot and it only allows me to use WEP security. I also found that My Profiles no longer works correctly (does not automatically switch between profiles based upon location or charging criteria), and My3G does not provide the same throughput.

If the issue was with only one app I would say the problem was the app. But in this case the issue is with every app I have.

Has anyone else had a similar issue with the Sn0wbreeze 2.7 Jailbreak?

The main thing that you have to remember is that don't update you iphone/ipod touch through the itunes.

I am having the same message appearing in itunes. It does not state that it is an OS update, just an update for carrier settings. Should we stay away from this update as well?? It is rather annoying to have it pop up every time I plug in my phone.
