What you’ll need:

1. Build your custom firmware with Pwnage Tool 4.1

Unplug your AppleTV from your TV and plug it into your Mac with a MICRO-USB cable (no power cable necessary), then launch Pwnage Tool 4.1. If iTunes starts, just ignore it and switch back to Pwnage.

You can pick either Simple or Expert mode – function seems to be the same but if using Expert, you’ll need to browse to the ipsw file manually, and then select ‘General’ and ‘Build.’ If you use Simple mode it will walk you through a little more quickly.

Once Pwnage Tool finds your restore file, click the blue arrow

You may be asked for your password in order to create the file. This takes a couple of minutes.

Grab your AppleTV remote because once the custom ipsw is finished, you’ll need to PRESS and HOLD ‘Menu’ and ‘Play/Pause’ on the AppleTV remote (you may want to obstruct your Mac’s IR port or position the AppleTV out of the line-of-sight to avoid unintended functions popping up).

Just follow the beeps and prompts for putting the AppleTV into DFU mode.


2. Installing the custom firmware bundle within iTunes

When you attached your AppleTV to your Mac, iTunes probably launched but if it didn’t or you closed it, just launch it again. Select your AppleTV under ‘Devices’ and Option-click the ‘Restore’ button. Browse to the file Pwnage Tool created which will have ‘Custom Restore’ in the title.

Let iTunes do its thing.

Done! At this point, you’ll connect AppleTV back up to your TV and run through all of the setup again just like it’s brand new. Luckily it’s pretty easy selecting your language, Wifi settings, Home Sharing, etc.

3. Installing frapps

Last step is installing a frapp (AppleTV app) because hey, what good is jailbreak without frapps? All that’s available at this moment is NitoTV. He’s put out these instructions:

1) SSH into your Apple TV2, the default password is "alpine"

(Editor note: on Mac fire up Terminal and type:

ssh root@ replace number with your AppleTV ip address listed in Settings-General-Network

password: alpine

then continue steps below)

2) Type "passwd" and enter a new password (if you wish)

3) Type: echo "deb http://apt.awkwardtv.org ./" > /etc/apt/sources.list.d/awkwardtv.list

4) Type: apt-get update

5) Type: apt-get install com.nito.nitoTV

6) Type: killall Lowtide

7) Enjoy

Step 3 doesn’t really scroll much text but 4 and 5 churn out a bunch of stuff. Answer ‘yes’ at the prompts. Step 6 reboots your AppleTV.

You haz success!
