[How To] Jailbreak iOS 4 iPodTouch 2G (MC) With Sn0wBreeze 1.7

Sn0wbreeze 1.7 utility allows jailbreaking for the iPodTouch 2G (MC) on iOS 4.0 and is available for download. With this release, you can jailbreak iPodTouch 2G (MC) if it's on OS 3.1.2 or you've SHSH blobs saved for OS 3.1.2. In order to create a custom iOS 4 and go for 4.0 firmware successfully you have to be on OS 3.1.2+ jailbroken.

IMPORTANT:

• iPhone 3GS with New BootRom, iPod Touch 3G, 2G (MC) users MUST be on firmware 3.1.2 or have SHSH blobs saved for it (needed for downgrade). Otherwise you’re still out of Luck. The exploit used in this hack has been patched in OS 3.1.3 so firmware 3.1.2 is a MUST.
• If you’re not on 3.1.2 firmware or don’t have saved SHSH blobs for it, you’ll have to wait for the Spirit jailbreak update which is almost ready. I think they are waiting for the next firmware update (iOS 4.1 or iOS 4.01).
• For iPhone 3GS (New BootRom), iPod Touch 3G, 2G (MC) users it’s a Tethered jailbreak. For those who don’t know, a tethered jailbreak device once turned off/Reboot/run out of battery, you need to connect it to computer and execute a tool to boot up the device.
• Once jailbroken then you can unlock iPhone iOS 4 with UltraSn0w.
• This guide is NOT for regular Windows users. So, proceed with precaution and follow the guide at your own risk. Let’s jailbreak iPod Touch 2G (MC) iOS 4 with Sn0wBreeze 1.7 and iBooty + Payload Pwner.

Sn0wBreeze 1.7 Supports:

• iPod Touch 2G (MC)
• iPod Touch 3G only if running firmware 3.1.2 and/or you have SHSH blobs for 3.1.2 (needed for downgrade)
• iPhone 3GS only if running firmware 3.1.2 and/or you have SHSH blobs for 3.1.2 (needed for downgrade)

How To Jailbreak iOS 4 iPodTouch 2G (MC):

Required:

• An iPod Touch 2G MC
• 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
• Sn0wbreeze V1.7
• iBooty V1.5
• Download iOS 4.0/3.1.2
• iTunes 9.2

STEP 1 : Pwning iBoot

1. Download this easy tool here — Payload Pwner-r5 // It will help you create the payload.
2. Extract it to a directory and run Pwner.exe

**Save the Payload where iBooty is.**

STEP 2 : Making a Custom IPSW

1. Download sn0wbreeze V1.7 from here
2. USE EXPERT MODE!
3. In General, Checkmark “Disable NOR Flash” <– THIS IS ESSENTIAL!!!!
4. 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 3: 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.

1. Download iBooty GUI here — iBooty V1.5 and Extract it.
2. Extract your Custom IPSW created by sn0wbreeze with 7-Zip or another un-archiver.
3. Grab the kernelcache and bring it into the same folder as ibooty.
4. Also grab iBEC from the folder “Firmware\dfu”.
5. Aswell as DeviceTree from the folder “Firmware\all_flash\all_flash.n88ap.production\DeviceTree.n88ap”
6. Rename your Kernel 4.0-Custom to “kernel.40″
7. Rename your iBEC 4.0-Custom to “ibec.40″
8. Rename your DeviceTree 4.0-Custom to “devtree.40″

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 4: Restoring to 4.0 + Booting

*Make sure your are on 3.1.2 when doing this*

1. Run iBooty and Select “Prepare Device for Custom Firmware“. Run the Process and if you see the image, you can proceed!
2. Now open iTunes and restore to the custom ipsw.

**When done, your device will go into recovery mode. It won’t boot.**

STEP 5 : Booting

Just Re-Run iBooty and select “Boot It”. If all goes well it will boot!

Enjoy! Hopefully iH8Sn0w can get a tool out there that will make all of this much easier.
