iOS 4.2 [Tutorial] GreenpoisOn RC6 Jailbreak: iPT4G, iPT3G, iPT2G, iPad 1G, and Apple TV 2G

[Tutorial] GreenpoisOn RC6 Jailbreak: iPT4G, iPT3G, iPT2G, iPad 1G, and Apple TV 2G

This tutorial is for jailbreaking OS 4.2.1

This is an adaptation of of my Greenpoison 4.1 tutorial. Found Here
I tried to simply include instructions for both firmwares in the same tutorial.
However, I decided making two separate tutorials would cut back on confusion.

This tutorial is for jailbreaking the following devices using the RC6 release of Greenpois0n:

- iPod touch (4th Generation)
- iPod touch (3rd Generation)
- iPod touch (2nd Generation), both MB and MC models
- iPad (First Generation)
- Apple TV (2nd Generation)

This is an untethered jailbreak for all these devices.

Before we start.

• You should be running iTunes 10.

NOTE: It may be wise to avoid syncing all your music and data until after the jailbreak is complete. If the jailbreak fails, then you may have to restore, so the long sync time would have been wasted.


1. Restore to OS 4.2.1. If you are currently jailbroken tethered with redsnow You can safely run greenpoison over it. However this results in excess files in the file system that may slow your device down. Therefore it is ill-advised.

TO PROPERLY RESTORE:

For those who are not currently Jailbroken: (Regular Restore)

• Connect Your Device
• Open iTunes
• Open your Device's Tab
• Click RESTORE
• Follow the Remainder of the Restore Process.
• Once Restored, You may restore to a previous backup. I personally advise against restoring to a previous backup of when you were jailbroken, due to issues that have occured in the past. However tinyman392 has indicated that it is indeed safe to do.

For those who are currently Jailbroken or have attempted to jailbreak, but failed: (DFU Restore)

• Connect Your Device
• Turn the device completely off. Slide to Power Off.
• Hold The Power/Sleep and Home buttons.
• Hold both until you hear the "recognize sound" from your computer.
• Release the Power/Sleep Button but continue to hold the home button.
• Your computer should find your device in DFU mode.
• The screen on your device should be completely black
• Open iTunes
• Open your Device's Tab
• Follow the Remainder of the Restore Process.
• Once Restored, You may restore to a previous backup. I personally advise against restoring to a previous backup of when you were jailbroken, due to issues that have occured in the past. However tinyman392 has indicated that it is indeed safe to do.

NOTE:At this time you should be completely restored. Close iTunes

2. Check your settings. On the ipod itself, Go to settings> general > about. You should be on OS 4.2

3. Download Greenpois0n RC6. Download it from Greenpois0n.com

4. Extract. Extract the files from the compressed folder using winrar or 7zip

5. Connect. Connect your iDevice to your computer, via the USB charging cable, while the Device is powered ON. If it's already connected from the restore then just continue.

6.Close itunes. If itunes opens, close it.

NOTE: If you leave itunes open, Greenpois0n will close it. I have confirmed that Greenpois0n should be ran with iTunes closed.

7. Run. Run greenpoisOn.exe AS ADMINISTRATOR

8.Turn Off. Turn the Device completely off. Press the power/sleep button and slide to turn off.

9.Prepare. In the GreenpoisOn Program: Click prepare to jailbreak.

10. Follow the directions in GreenpoisOn.They will be as follows:

-Get ready to start. 3 seconds

-Hold the power/sleep button for 3 seconds.

-While still holding the power button, press down the home
button at the same time. Hold for 10 seconds.

-Release the Power/Sleep button but continue to hold the home
button. Hold for 20 seconds (Should not take entire 20 seconds)
_______________________________________________________________

11.Jailbreak. On the next screen in GreenpoisOn, click "Jailbreak".

12. Wait. GreenpoisOn will install and add "loader" to the home screen on your ipod.

13.Install Cydia. Open loader on your Device, and install cydia, This requires wifi. If you dont have reliable wifi, then wait until you do, partial Cydia installs will force you to start this over.

If you need to, go back and sync all your music and data at this time.

That's it! Now you can use Cydia to install tweaks, apps, mods, and themes.

Good luck

Well described, thanks!

I tried jailbreaking both by setting as a new device or by restoring backup.
Didn't work.
I've been trying to do it on two computers.
Windows 7 64...

You are entitled to your opinion but that's not really appropriate terms for you to hate me. In my experience, the edited plists( as in plists that are part of the file system that you personally changed ie.. native wallpaper, unified ipod..etc) can conflict with processes on the new OS.

could i do this?
i jailbroke but cydia crashes at startup

Then cydia dint properly install. Remove cydia installer from the manage page in cydia. This will uninstall cydia. Then reinstall it from loader.

If you already uninstalled loader then you have to start all over.

Let me clarify. The Jailbroken plists as in plists form jailbroken apps serve no problem whatsoever. I agreed with you on that.

The plists that you edit to change how the system behaves are saved, as far as I know, and can cause issues on a fresh restore. The NXXXX.plist and the Settings.plist and the sounds.plist are all saved from my knowledge and when they carry over they have caused issues for people. It's a fair warning and nothing more.

Good point.

However redsnow isnt compatible with the 2GMC. If he has a 2GMC he has to start over.

If you have a 2GMB reinstall cydia via redsnow.
