Tutorial [New 2024 - iOS 14/15/16] How To Install Theos & SDKs on your iOS Device!

[Rook 550.3k iPad Pro (2nd gen) 17.4 Donor]

The tutorial below is no longer applicable. Please use the official tutorial to install theos available on the official GitHub page. It's a simple command. 

Requirements:
- Jailbroken iDevice
- Add Repo to Cydia: https://apt.bingner.com (unc0ver) or https://apt.procurs.us (odyssey) depending on your jailbreak type. If you don't know, use the theos-install script linked above.

 

All iOS Versions Instructions:
1. Using any (iOS) Terminal (we'll be using PuTTY for this tutorial), login as root and install theos dependencies using these commands:

apt-get install -y --force-yes org.theos.dependencies

2. Now we need to setup THEOS variable and install location. We will be installing theos into /opt/theos but you can choose any other location. If you are using Odyssey Jailbreak then you will need to change the .profile to .zprofile since they use ZSH.

NOTE: You must install theos outside of /var otherwise you are likely to get killed: 9 when running nic.

echo 'export THEOS=/opt/theos' >>~/.profile
echo 'alias theos="$THEOS/bin/nic.pl"' >>~/.profile
source ~/.profile

If source command does not work for you, then simply restart your PuTTY.

3. Downloading theos & sdks:

Please run the theos-installer from the instructions here: https://theos.dev/docs/installation-ios

 

And you're done! You now have installed theos & theos dependencies on your device. To start a new project, cd into the folder you want to store your projects in and run:

$THEOS/bin/nic.pl
or
theos

 

TIP If the above does not work for you, there is also a new way to automatically install theos provided by the theos developers here: https://theos.dev/docs/installation-ios

 

Additional Information:
- If you want to use a different SDK, go to your /theos/sdks directory and remove the iPhoneOSx.y.sdk you do not need. By default, iOS 9 SDK is used at the time of writing this. This may change if this gets updated.
- To update theos, see the official GitHub Instructions: https://github.com/theos/theos/wiki/Installation#updating
- You can add extra helpful aliases by running commands like: echo 'alias mpi="make package install"' >>~/.profile && source ~/.profile so when you want to make and install your package, you can simply run 'mpi' command.
- If your SDK is failing to install, try deleting the sdks folder in your theos directory and then run the git command.
- If you use a different terminal and you get errors about missing .mk files, you will need set up the THEOS variable for that terminal.
- To install theos on your Windows 10, see this topic.

 

Special thanks to everyone that has worked and continues working on theos!

Are you using git from Saurik’s repo?
