Jailbreak iOS 4 on iPod touch 3G and iPod touch 2G MC Model

Sn0wbreeze 1.7 for 4.0 has been released. Just like PwnageTool 4.0 / 4.01 for Macs, you can now create custom pwned / jailbroken ipsw files on Windows too which can now jailbreak all iOS devices (except iPhone 4) on iOS 4, including iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G. But there is a catch to it! You will need to have their SHSH blobs saved for iOS 3.1.2 in order to successfully jailbreak these devices on iOS 4. Also the jailbreak for iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G on iOS 4 will be tethered, which means whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on.

The step by step guide to jailbreak these devices is almost exactly similar to the last release. Simply follow the guide posted here to jailbreak your iPod touch on iOS 4 using Sn0wbreeze 1.7. Once you have created a custom firmware file, you can simply restore to it via iTunes 9.2. If there are any changes, we will redo the guide and post it again here.

If you don’t have your 3.1.2 (NOT 3.1.3) SHSH blobs (ECID SHSH) files saved, you will have to then wait for the next version of Spirit which is likely to be released as soon as Apple releases the next firmware update i.e. iOS 4.0.1 / 4.1 and it will support all iOS devices including iPhone 4.

Download Sn0wbreeze 1.7 for Windows

UPDATE 1: ok guys, you will need to follow the following instructions to jailbreak iPod touch 3G and iPod touch 2G (MC models) on 3.1.2, or with 3.1.2 SHSH blobs saved.

Warning Note: All the standard warnings apply. This is for advanced users only. Only proceed if you think you know your iPhone/iPod touch inside out.

**BEFORE PROCEEDING, ENSURE THAT YOU HAVE YOUR iPod/PHONE BACKED UP!**
THIS TUTORIAL ASSUMES YOU ARE ALREADY ON 3.1.2!
Q: Why not 3.1.3???
A: The exploit used is closed in 3.1.3 and beyond.
——-
WHAT YOU WILL NEED:
* An iPhone 3G[S] or iPod Touch 2G MC or iPod Touch 3– new bootrom
* 3.1.2 already installed or 3.1.2 installed via SHSH blobs. <– Broken blackra1n’d devices will work. (Especially if Spirit messed you up!).
* Payload Pwner-r5 (http://www.mediafire.com/?zgzynznwn0y)
* sn0wbreeze V1.7
* iBooty V1.5 (http://www.mediafire.com/?mmnjti0midn)
* 3.1.2/4.0 firmware downloaded.
* iTunes 9.2 Installed
——-
STEP A : Pwning iBoot
I : Download this easy tool here — Payload Pwner-r5 (http://www.mediafire.com/?zgzynznwn0y) // It will help you create the payload.
II : Extract it to a directory and run Pwner.exe

**SAVE THE PAYLOAD WHERE iBooty is.**
——-
STEP B : Making a Custom IPSW
I : Download sn0wbreeze V1.7
II : USE EXPERT MODE!
III : In General, Checkmark "Disable NOR Flash" <– THIS IS ESSENTIAL!!!!
IV : Build it. It will be on your Desktop.

**CUSTOM BOOT LOGOS THAT ARE MADE IN sn0wbreeze WILL NOT WORK ON NEW BOOTROMS!**
*Mac Users : PwnageTool does not have this option. I don’t think it will ever be in there. Use a Windows Virtual Machine or friends PC to create your firmware.*
——-
STEP C: iBooty Prep.
Most of you know of the utility "iBooty" that I made for Aki_nG.
It will work as long as you place all of the correct files there.
I : Download iBooty GUI here — iBooty V1.5 (http://www.mediafire.com/?mmnjti0midn) and Extract it.
II : Extract your Custom IPSW created by sn0wbreeze with 7-Zip or another un-archiver.
III : Grab the kernelcache and bring it into the same folder as ibooty.
Also grab iBEC from the folder "Firmware\dfu".
Aswell as DeviceTree from the folder "Firmware\all_flash\all_flash.n88ap.production\DeviceTree.n88ap".
IV :
* Rename your Kernel 4.0-Custom to "kernel.40"
* Rename your iBEC 4.0-Custom to "ibec.40"
* Rename your DeviceTree 4.0-Custom to "devtree.40"
***MAKE SURE YOU REMOVE THE .img3/.dfu/etc extensions!***
======
Your folder should look like this :
– iboot.payload <– Created with Payload Pwner.
– devtree.40 <– Grabbed from Custom IPSW made by sn0wbreeze.
– ibec.40 <– Created with Payload Pwner.
– bspatch.exe <– Comes with iBooty.
– iBooty.exe <– Comes with iBooty.
– kernel.40 <– Grab from Custom IPSW made by sn0wbreeze.
– sn0w.img3 <– Comes with iBooty.
– wait.img3 <– Comes with iBooty.
======

STEP D: Restoring to 4.0 + Booting
——-
*MAKE SURE YOU ARE ON 3.1.2 WHEN DOING THIS*
I : Run iBooty and Select "Prepare Device for Custom Firmware". Make sure that your device is in Recovery Mode (The one with the iTunes Connect Logo). Run the Process and if you see the image, you can proceed!
II : Now open iTunes and restore to the custom ipsw.
***WHEN DONE, YOUR DEVICE WILL GO INTO RECOVERY MODE. IT WONT BOOT.***
——-
STEP E : Booting
I : Just Re-Run iBooty and select "Boot It". If all goes well it will boot!
