Cydia installer works on Jailbroken iOS device. You can install it, if Cydia is not working properly, crashing again and again and so on.
Suppose, you have jailbreak your iOS device and Cydia is not working properly or giving errors while installing apps, searching apps from default sources or any other, then you need to Reinstall Cydia using deb packages.
You can re-jailbreak too, it will also install Cydia again, however, you should fix the errors, if possible. In the end, if there is nothing to fix and still Cydia doesn’t work, then re-jailbreak.
How to Install Cydia
Cydia comes as an optional installer with every jailbreak utility. You don’t need to download and install it externally. But, in some cases, we need Cydia installer to install it. You can do it without jailbreak your iDevice again. Follow below troubleshooting steps…
1 Cydia Installer
If you have jailbroken your iOS device once, you can download Cydia installer from Saurik’s website and install it without jailbreak again. It comes in deb packages and can be install easily. It will fix all errors and updates default repo sources.
2 Reinstall Cydia
If you are getting errors while accessing Cydia and it’s features, I would suggest you that you should fix those errors manually, before getting Cydia installer for fresh installation.
3 Update it
Sometimes after updating to new installer version, errors may be fixed automatically. I have seen many cases, user need to update their Cydia installer to fix the errors.
4 OpenAppMkt Installer
If you are looking for Cydia without jailbreak or jailbreak + Cydia installer, then OpenAppMkt is the best place ever. However, we can not say with guarantee that it will work or not, because we have never tested those packages. But, I have seen a installer that is made by Hackulo.us. Take a look at that picture…
Without jailbreak, its very low chance that you will get working Cydia installer at all. But yes, if you have jailbreak once upon a time, you can update, reinstall and fix Cydia installer easily.
