If your Apple TV is jailbroken but doesn't have a third-party software installation menu system, NitoTV is an excellent, free choice.
Mac users:
1. Download and run (on your Mac) the Rowmote Helper and NitoTV Installer.
2. You're done! Connect via Rowmote.
Windows users:
1. Install nitoTV and Rowmote Helper:
a. Connect to your Apple TV via PuTTY or the SSH client of your choice.
Server: apple-tv.local
Username: root
Password: alpine
b. Run the following command:
apt-get update; apt-get install com.nito.nitotv; apt-get install com.rrr.rowmotehelper-atv2
2. You're done! Connect via Rowmote.
You can later perform updates by selecting 'Update All' again in the NitoTV software menu, which will automatically upgrade every installed package including Rowmote Helper. You can install other third party software via NitoTV's software menu, too.
To connect with Rowmote after installation, launch Rowmote, tap Settings, select 'Apple TV', and tap 'Done'.
