greenpois0n for the AppleTV is released

The final version of greenpois0n has been released. This is the version that includes the AppleTV 2G which was not included in the previous release candidates. Installation was really really simple. For this jailbreak you’ll need the power cord, Apple remote and microUSB cable. The instructions are as follows:

  1. Start greenpois0n. And click Jailbreak
  2. Plug in the microUSB cable first.
  3. Plug in the power cable.
  4. Press Menu and Play on the Apple Remote for 7 seconds.
  5. After a minute it should complete. Don’t disconnect the AppleTV right away. It will need a minute to build a ramdisk.
  6. After an appropriate amount of time you can unplug the AppleTV and reconnect it to your TV.

Once I connected it to the TV and let it boot I was presented with a new menu option to install the payload software. Make sure your internet connection is on and run the script to install Cydia and NitoTV. After Cydia is installed the AppleTV should reboot again and the greenpois0n menu option should disappear and nitotv will be in its place. Now you can install software (like XBMC-ATV2) with just a click.

One problem I did have was that XBMC didn’t install. You can connect to your AppleTV using SSH root:alpine is the default username and password. Run the command below to install it.

Apple-TV:~ root# apt-get install org.xbmc.xbmc-atv2

Note, that it might throw an error at the end. You can ignore this because it will be installed and fully functional. The TV menu should change but if not you can restart it by sending a killall AppleTV to restart the GUI.

Greenp0ison released

It certainly took long enough but chronic-dev has released greenp0ison for the Mac (and eventually windows and Linux). The server was down earlier so I’ve added a link in the bottom of the page to store a copy here until they get their servers together. This works on the iPhone 3GS, iPhone 4, iPad, and AppleTV2. For now it only does jailbreaks so if you are needing to unlock the phone you’ll have to continue waiting until a new version of ultrasn0w (or whatever it will be called) is released.


Writing iPhone applications for jailbroken iPhones

As a developer I don’t enjoy paying for things when I don’t have to. One of them happens to be Apples iPhone Developer program. I could find better ways of spending $99. Debugging my own stuff isn’t one of them. So what is a developer to do when he can’t or won’t pony up the money to be allowed to load and debug his own applications. He uses that tiny developer brain to bypass all the checks that’s how.

I’m not going to go into the ins and outs of jailbreaking the iPhone. There are plenty of tutorials on the net to do exactly that. If you are in over your head at this point you should probably bail now, shit is definitely not going to get easier from here on out.

Creating a certificate

You’ll need your own self-signed certificate. iPhone OS will check for it, jailbreaking will tell it that it’s good, regardless of who it came from. So crack open Keychain access and create one for yourself. It’s in /Applications/Utilities/Keychain From the menu choose Certificate Assistant > Create Certificate.


Give it the name “iPhone Developer” and check overide defaults.

Give yourself enough time. 10 years sounds about right. And change the type to Code Signing.

Add as much or little information as you want to the personal information screen.

After here, click next until the end. It should be shown in your Keychain Access application list.

Update the Developer stack

We’ll need to make a modification to the Info.plist of the SDK. Go to /Developer/Platforms/iPhoneOS.platform. Create a backup of Info.plist and open the original in Property List Editor. Change all instancese of XCiPhoneOSCodeSignContext to XCCodeSignContext. There are 3 instances of them in SDK 3.1.2. There might be more or less in future versions.

Back to XCode

In XCode open your project and change the Active SDK to iPhone Device – 3.1.2. Run the build command with Command-B. Go to the Directory with your project, open the build folder and into the Release-iphoneos or the Debug-iphoneos folder you’ll find the executable. We’re going to need to get this file into the iPhone.

Copy your application to iPhone

You won’t be able to get your application onto the phone using the normal channels. iTunes won’t allow it. So the alternative is to copy it to the phone using SSH or iPhone Explorer. As with all things Mac, iPhone Explorer provides a GUI. And a GUI is always handy. Using iPhone Explorer go to the /Applications folder on the device. And upload your app folder. When complete it should appear like this. In some cases the app won’t be set to executable. If this is the case you’ll need to run the “chmod a+x” on the app folder to allow it to run.

Your application won’t be present on the springboard. For that you’ll need to restart the springboard. There are jailbreak applications that allow for this. You can also install the UIKitTools and run uicache from the commandline to update the springboard without restarting it.
