1 ) Launch Cydia on your jailbroken iOS device and tap on the ‘Manage’ button located at fourth position in the bar below.
2 ) On the ‘Manage’ screen you will see a menu with links to Packages, Sources and Storage. Tap on Sources. This is where you can add a repo in Cydia.
3 ) Now on the Sources screen click on the ‘Edit’ button located on top right side of your screen.
4 ) Next you need to click on the ‘Add’ button. From here you can also delete a repo which has already been added if you want to.
5 ) Now Cydia will ask you to Enter Cydia/APT URL. You need to enter the URL of the repo you are trying to add exactly as it is.
6 ) Once you have written the address of the repo you are trying to add tap on ‘Add Source’ button. Now Cydia will verify the URL you have entered.
7 ) Once the address has been verified Cydia will warn you about the repo. It doesn’t warn users about all the repos but if it does then tap on ‘Add Anyway’ button to proceed.
8 ) Now Cydia will download data from the source you have just added. This will take a few seconds.
Done! That’s how you add a repo in Cydia.
Your source has been added and you can download anything you want from this repo. The source you have added will appear in the list of sources in Cydia and you can delete it from there whenever you want.
