If you have some trouble running Cydia, then you don’t have to worry since there’s a way to fix that too. Running on a jailbroken iDevice, Cydia gathers numerous apps from different community apps developers in one place. You can download most of these apps for free or for a low price. Taking into account these aspects, I bet you’d like to use Cydia or to reinstall it again on your iDevice in case it doesn’t work properly anymore.
What you have to do in order to enjoy Cydia again is to jailbreak your iPhone, iPod or iPad. There are jailbreaking softwares that feature a default installation for Cydia. So, if you check the Install Cydia option when you jailbreak your iDevice, then Cydia will be installed automatically. In case, something goes wrong and Cydia doesn’t work properly, then you can use this method to re-jailbreak your iDevice without having to worry that this will damage your iPhone, iPod or iPad. After this, Cydia should be running normally again.
Anyhow, if you want to enjoy your favorite apps once again, you have to know that this is possible even without jailbreaking your iPod Touch, iPad and iPhone. So, here are the steps you will have to follow in order to use Cydia again without jailbreaking your iDevice:
1. The first thing to do is to download the Cydia package. It won’t be difficult to find it since there are many sources that offer this package but you’ll have to make sure that you download it as deb.package.
2. Now in order for you to SSH the files into your iDevice to the ROOT folder, you will have to use WinSCP or CyberDuck.
3. After the deb.package is placed into the ROOT, you will have to open up the Mobile Terminal and then type dpkg -i /Cydia.deb to install the package and the killall -HUP SpringBoard command to re-spring your iDevice.
If you’ve followed these steps carefully, Cydia should work just fine now.
