What is Cydia? What it does!
CydiaIt is a software manager that lets users find and install all kinds of packages on jailbroken iOS devices, including software, system modifications, themes and ringtones. Slightly more professionally Cydia is a graphical interface front-end to Advanced Packaging Tools (APT) and dpkg, as well as a decentralized software repository.
Father of Cydia
Cydia is developed by Jay Freeman (also known as "saurik") and his company SaurikIT.
Cydia announces shutdown
Jay Freeman (Saurik), the father of Cydia in 2018, posted on Reddit that he was considering shutting down the Cydia Store at the end of the year, promising to release a more detailed and official statement this week in response to current vulnerability issues and future developments in Cydia.
Cydia's version is stuck forever at version 1.1.30, which was launched at 02:45 on February 16, 2017

Installing Cydia on iOS 15 and higher?
Reason?
People who generally want to install Cydia on iOS 15 and later devices, not because of habit, do so for these reasons:
- No, what I want to use, I have to use Cydia to install, nothing else will install
- The plugin I'm going to use can't be installed/used without Cydia
- The plugin I'm using doesn't support Sileo or other package managers can't be installed
Some of these people even paid someone else to do the jailbreak, because after the jailbreak the other party was irresponsible for not assisting them in installing the required plugin Tweaks (or the person who provided them with the service was so bad that they were unable to complete the corresponding operation), and then mistakenly believed that Sileo was unable to install some of the plugin Tweaks, and that Cydia had to be used.
typical example
Plug-in installation
It's a lot like installing the same app through different brands of phones:
- Through the Android brand, iPhone
- Different brands understood as different package managers (Cydia/Sileo)
- Simultaneous installation of WeChat (user required plugin Tweaks)
- iPhone needs to have WeChat finally installed via AppStore (A package manager)(Plugin Tweaks)
- Xiaomi installed the final installation of WeChat through the Xiaomi App Store (M Package Manager)(Plugin Tweaks)
- OPPO finally installed WeChat via OPPO App Market (O Package Manager)(Plugin Tweaks)
Different devices went through different ways (package managers), but all ended up successfully installing WeChat (plugin Tweaks). In fact, Cydia/Sileo, etc. are package managers, a tool used to manage the behavior of installing, uninstalling, and updating software packages, so it doesn't matter which one you go through, at least in terms of installing.
Plugin Tweaks feature availability aspects:
- On iOS 15 and above, users only need to make sure that the plugin is compatible with the current version and device, and it has nothing to do with which package manager to use!
- On iOS14 and below devices may have to consider more, such as Cydia Substrate/MobileSubstrate/Substitute/LibHooker issues, but on iOS14 and below devices, users are free to choose to use the pre-installed Cydia or Sileo Jailbreak tool, because the genuine Cydia is to support iOS14, so there is no such problem, a very small number of devices iOS14.6-14.8.1 can not use Cydia, but still in accordance with the plug-in Tweaks at the same time compatible with your device and version on it.
- Such as: on the iPhone 12 14.6 device can only use Taurine (comes with Sileo package manager) jailbreak, jailbreak after the installation of the corresponding plug-in problem, in determining the A plug-in Tweaks compatible with iPhone 12 iOS 14.6 under the premise of this device ultimately in the Taurine jailbreak environment 100% can be installed and normal use of A Plugin Tweaks. if A Plugin Tweaks is not compatible with iPhone 12 iOS 14.6, then it can also do the installation completed, but because of its compatibility is bound to be unable to use it properly, for example, even the home screen/in-device does not appear to show the plugin icon (Sileo in the display of the installed), at least its function will be unavailable because of the compatibility (need to be the A Plugin developer) (need A plugin developers to update and upgrade their plugins instead of wasting time on jailbreaking)
Through the above introduction, it is clear that the need for Cydia users are encountered plug-ins can not complete the installation of the problem is due to the jailbreak personnel technology is not solid resulting in the completion of the installation, because the installation of a plug-in, is related to Cydia, Sileo, Zebra, and other package managers is not relevant, and the installation of plug-ins can be used normally or not, depending on the plug-ins on the current device and version compatibility! The installation of the plugin is not completed.
A warning from the father of Cydia
Installing Cydia on iOS 15/16/17/18 and future higher versions? Between the cessation of updates in 2017, then the phasing out of maintenance of important Cydia features in 2020 to 2022 Jay has reminded users countless times that you can only install Cydia on older versions of your device, and that the closest jailbreak tools to date that come with the original Cydia pre-installed are Checkra1n and Unc0ver, both of which support up to iOS 14.
Jay's countless reminders are due to a large number of user feedback that they have been scammed out of funds and Cydia not working due to installing Cydia on iOS 15+ devices, not working because those are not genuine Cydia, these pirated versions of Cydia may not even be able to implement the APT and dpkg core functionality, so naturally it is unusable, and they either have been scammed out of funds, or they have downloaded a bunch of The problem is because those are not genuine Cydia, these pirated Cydia may not even be able to realize APT and dpkg core functions, naturally they can't be used, either they are cheated of funds, or they download a bunch of malware (ads mostly), which reaches a revenue for the pirated Cydia publisher.






With the passage of time to 2023, compatible with iOS15-16-17 jailbreak tool gradually surfaced, some bloggers have shared the Palera1n or Dopamine jailbreak environment to install non-genuine Cydia (part of the functions available version) of the method, but the tutorials released by these bloggers, apparently to look at this part of the "white" user traffic, because as long as there is a base of expertise people know that a jailbreak tool pre-installed is obviously the best. But the tutorials posted by these bloggers are obviously aimed at this part of the "white" user traffic, because as long as there is a professional knowledge base of people, we all know that the jailbreak tool pre-installed is obviously the best, the development of a jailbreak tool often requires a team to complete, the initial version of the release, but also according to the user's feedback to iteratively update, and ultimately update the jailbreak tool to a stable and excellent.
reach a verdict
As Jay said: If I could give some advice to "Past Jay", it would be "Don't waste your life on Cydia". And that's exactly what I'm saying to you who are reading this article. Because you are reading this article, it means that you are experiencing a similar problem, and yes, this article is for you!
