Its not news that you can do it, you need developer account for 99bucks a year or reload it every 7 days for it to work,, Its really a hazzle to get it up n running, i tried it for my self a few times but it didn't work for me.. got som weird errors every time.
Follow the guide using impactor to sideload kodi and it works like a sharm.
If you get the wrong password error when prompted for password, you have to log in to your apple account and make a temporary password for the app because you use two step authentication.
Here's a quick "guide" so you understand the installation process..
To make the .ipa file follow the guide above, in short,, download kodi deb file for apple tv, extract with unarchiver and extract the mentioned file and add it to a folder named Payload, make zipfile and rename file extension to .ipa ( where the file is? use google =)
Save the file for use later on.
Drag the .ipa file to the impactor app to start sideload it.. Works for 7 days but i think you can just sideload it again after 7 days and update it for 7 new days without the need of entering the settings and plugins again.
This method you dont need to manage and play around with xcode and such..
I can confirm that my instructions only worked for 7 days and kodi stopped working after that. Was afraid that i needed to enter the m3u line and all the settings manually with the boring remote. BUT!! The nice thing was that i only needed to inject the app once again and all was up n running like before, no need to enter the settings again. Took me about 1 minute and it works like a sharm for 7 more days, not that much work for the joy it gives me and that is ok for me.
So,.. All works great for me on my apple tv4 and i dont need to add another device in my bedroom. I get a error in the end of the software updating but i can ignore it since all works like it should anyways..
Now lets install android on my tvip410 and see how that compares to the ui i comes with.
