Jailbreak Apple TV2 on iOS 4.2 with PwnageTool [HowTo]

About a week ago Apple released iOS 4.2 version for Apple TV 2G. And if you want to run third-party apps and plugins on Apple TV2 like nitoTV, GrooveShark Client and Plex Client, here is step by step guide to jailbreak the device on iOS 4.2 with PwnageTool.

The PwnageBundle which is being used in this guide to jailbreak ATV2 on iOS 4.2 is not from official sources but it works without any problem and is tested by @nitoTV, the developer behind popular nitoTV plugin.

This whole guide is taken from ReadMe file present in PwnageBundle folder because we couldn’t find a better way to explain all these steps. Very very special thanks to @nitoTV for this awesome guide!

Disclaimer: If you do not have your SHSH blobs backed up for your AppleTV at 4.1 i HIGHLY advise avoiding any upgrading whatsoever, tethered or not, until a real proper jailbreak is available. If you don’t understand the above GO BACK NOW, do NOT attempt the following.

Made it this far? Another warning:

If you aren’t a developer or someone trying to tweak iOS 4.2 the following jailbreak is STRONGLY discouraged. Booting tethered on the AppleTV is an easy process, but it is still a PITA that a casual user would probably not have the desire to put up with. Read the ENTIRE documentation at least once before running through the process.

You will need a computer that is close enough to your AppleTV that it can be plugged into USB, power and HDMI without any major movement of the AppleTV itself), if you don’t meet this requirement the following is impossible, unless your microUSB cable is REALLY long.

Required:

Step 1. Move this entire folder to the desktop (only necessary if you are following these directions verbatim)

Step 2. Open Terminal app (if you don’t know where this is, you REALLY shouldn’t be doing this.

Step 3. run the following commands (this will fail if you didn’t move this folder to the desktop, PwnageTool almost MUST be in your /Applications folder)

cp -r ~/Desktop/tethered/AppleTV2,1_4.2_8C150.bundle /Applications/PwnageTool.app/Contents/Resources/FirmwareBundles/

cp ~/Desktop/tethered/Info.plist /Applications/PwnageTool.app/Contents/Resources/CustomPackages/CydiaInstallerATV.bundle/Info.plist

Step 4. Run PwnageTool on the 4.2 ipsw (if you don’t know how to do this, again you REALLY shouldn’t be here) saving into the ~/Desktop/tethered folder with the default name PwnageTool gives it (AppleTV2,1_4.2_8C150_Custom_Restore.ipsw)

Step 5. back in the terminal run the following:

unzip -j ~/Desktop/tethered/AppleTV2,1_4.2_8C150_Custom_Restore.ipsw Firmware/dfu/iBSS.k66ap.RELEASE.dfu kernelcache.release.k66 -d ~/Desktop/tethered/

Step 6. Restore the AppleTV to the ~/Desktop/tethered/AppleTV2,1_4.2_8C150_Custom_Restore.ipsw firmware (your AppleTV SHOULD be in DFU mode after finishing up with PwnageTool)

NOTE: Do not install any packages through cydia in expert mode, this produced very unpredictable results.

Step 7. Unplug and then replug the USB, after the AppleTV has finished started up (will be blinking steadily), plug in the power cable

Step 8. Run the following commands in terminal:

cd ~/desktop/tethered

./tetheredboot -i iBSS.k66ap.RELEASE.dfu -k kernelcache.release.k66

NOTE:  it will loop a complaint re: DFU mode, just ignore this, once you are finished getting in DFU mode tetheredboot will take over.

Step 9. MANUALLY put the AppleTV in DFU (*DO NOT USE PWNAGETOOL*)

DFU Mode:

  • Hold Menu for 7 Seconds
  • Without releasing menu, press power for 7 seconds

successful output from tetheredboot looks like this:

libusb:error [darwin_transfer_status] transfer error: device not responding (value = 0xe00002ed)

Step 10. If all went well, unplug USB and plug in HDMI and your AppleTV should be ready to go. You will need to repeat 7-9 every time you restart your AppleTV, this isn’t a convenient process by any stretch!

Step 11. To get nitoTV installed ( i couldn’t get the cydia, or custompackage sot work in PT)

apt-get install wget

wget -O- http://apt.awkwardtv.org/awkwardtv.pub | apt-key add –

echo “deb http://apt.awkwardtv.org/ stable main” > /etc/apt/sources.list.d/awkwardtv.list

apt-get update

apt-get install com.nito.nitotv

Note: The “Finder” app name changed from lowtide to AppleTV, this means any appliances installed through nitoTV or apt-get will not show up unless moved from /Applications/Lowtide.app/Appliances to /Applications/AppleTV.app/Appliances, we are working on a solution for this, hopefully it will be resolved in beigelist in the near future.

  1. Thanks for the tutorial, but I am getting stuck at Step 9 : Manually putting into DFU Mode. When you tell us to hold the power button, what button are you talking about?

  2. “wrong firmware bundle selected” msg when I select 4.2 firm on pwnagetool 4.1.2 or 4.1.3 any suggestion?

    • go through the steps up top again, you modify pwnage tool and the bundle to accept it.

    • The folder you download from the link mentioned at the bottom of above post. Unzip it and place it at desktop.

  4. This doesn’t work for AppleTV 2 on 4.2 firmware. When installing things in the Lowtide directory it will not show up on screen. However if you move the folder to AppleTV it will show up on reboot but then crash and stick on a reboot loop until you remove the folder again!!
    You even get the reboot loop if you leave it in Lowtide and create a symbolic link in AppleTV!!
    There doesn’t seem to be a way round it. Even changing all the ownership permission etc doesn’t help.
    However for some reason it will not do the reboot loop and will stick with the app showing on the Apple TV home screen if you unplug the internet during the reboot loop.
    But if you plug back in the internet or connect back to a wifi it will then reboot and get stuck in the loop again!!

    Anyone have any ideas??? lol

    • The first thing, if I didn’t mention in the post, is that it is tethered jailbreak. You will have to connect your device with PC and use software like Redsn0w to boot the Apple TV. Download Redsn0w, select “just boot tethered right now” to get rid of this reboot loop.

  8. Everything worked until I plugged the HDMI cable back in. The “Welcome” screen (choose language, technically) screen popped up, but I was unable to control anything with the Apple Remote. The light on the ATV still would blink when I pressed any buttons on the Apple Remote, but the until would not indicate any change (up down, or enter) on screen.
