Cydia Eraser was once known as Cydia Impactor, but it was updated and given a new name by its creator, Saurik. It is perhaps one of the most powerful tools that an iOS user who uses Cydia regularly could have because it is used to remove Cydia without updating you to a later version of the iOS.
Cydia Eraser is very easy to install and use; just follow the steps below. Please make sure you install it as soon as you have installed Cydia, it is the only way to ensure your iOS version is retained and you can reinstall Cydia at any time.
How to Install Cydia Eraser:
Because Cydia is constantly being patched by Apple, the usual methods of restoring your device will mean that you can no longer install it once Cydia has been removed. It is strongly recommended that when you install Cydia, you should immediately install Cydia Eraser to protect your iOS firmware. Here’s how to do it:
- Plug your iPhone or iPad into your PC or Mac and open iTunes
- Back your data up, this is an important step so don’t skip it
- Keep your device connected and make sure that you have an absolute minimum of 20% battery ( more is better )
- Launch Cydia on your device and search for Cydia Eraser
- Install it the same way you do any Cydia app
- When your device resprings, you will see the app icon on your home page
How to Use Cydia Eraser:
If you need to remove Cydia from your device, here’s how to do it with Cydia Eraser:
- Open Cydia Eraser by tapping the icon on your home page
- Tap the option to Delete All Data and Unjailbreak Device
- On the new window, tap Delete All to confirm your choice
- Leave things alone, when the process has finished, your device will reboot back to the original iOS version without Cydia; you can now set your device up
Cydia Eraser Features:
Anyone who has used Cydia long term will already be aware of the main features but, for the benefit of those who haven’t used it:
- Cydia Eraser removes Cydia from your iOS device without affecting your iOS version. Normally, if you were to use iTunes to do this, your device would be updated to the latest iOS firmware, so this feature is very important
- This means Cydia is removed, but you may install it again on the same iOS version
- Removes all signs of Cydia so, to all extents and purposes, it was never there; if you need to take your device into an Apple repair shop or you are selling it, nobody will ever know that Cydia was ever installed. This keeps your warranty safe too.
- You don’t need your PC or Mac as Cydia Eraser works directly on your iPhone or iPad.
Other Ways to Delete Cydia:
Deleting Cydia from your iPhone or iPad without using Cydia Eraser is also possible and is quite simple. This is for a scenario where you do not have access to the Cydia Eraser app on Cydia Store. This also works to delete the Sileo jailbreak appstore.
Method 1: Using Succession App
This method involves using a brand new jailbreak tool called Succession. This allows you to remove your jailbreak without affecting your iOS version, leaving you free to jailbreak again whenever you want.
- Launch Cydia and tap on the Sources tab
- Tap on Edit and then Add
- We need to add a repository so type in this URL – https://repo.dynastic.co
- Tap on Add Source – the repository will be added to Cydia.
How to Use Succession:
Using it is easy enough:
- Open Cydia and tap the Search tab
- Type in Succession and, when the result appears, download it as you would any tweak
- Tap the Succession icon on your home page
- Tap Download Clean Filesystem on the main Succession page
- Tap on Start Download and wait; this may take a while as the IPSW has to be downloaded
- When the Download Complete notification appears, go back to the main Succession window
- Tap on Prepare for Restore
- Tap on Erase iPhone
That’s all; once the process is complete, your iPhone reboots, and you can go ahead and set it up again.
Method 2: Restore the iPhone or iPad
The following process of deleting and removing jailbreak from your device also upgrades your device to the latest supported version of iOS, which might not be jailbreakable. So there is a trade-off in this method, and hence should only be the last resort to remove jailbreak from your device.
This method will remove all your data, and your device will be restored to the latest iOS firmware. Before you start:
- Make sure iTunes is on the latest version – open it, click on Help > Check for Updates and follow the on-screen directions
- Back your data up using iTunes or iCloud
- Disable your passcode, Touch ID and Find my iPhone or iPad
When you have done all that:
- Launch iTunes and plug in your device
- If requested, type your passcode on your device
- Click on Yes when you see the Trust This Computer message
- Click on the Device Summary for the device and then click Restore
- Click Restore again and leave your device, when it’s done it will reboot to the Hello screen on the latest iOS version – the jailbreak app is gone, and you can start again
Method 3: Restoring from iTunes Backup
Hopefully, you have been making regular backups of your data:
- Open iTunes
- Plug your device in and input your passcode on your device
- If you see the Trust this Computer message, tap Yes
- Click on the device summary
- Click on Restore Backup
- A list of your backups will appear, choose one from before you installed Cydia
- Click Restore and leave it – iTunes will now restore to your chosen backup.
- If asked, input your passcode and make sure your device remains connected to your computer throughout the backup – if not, it can’t sync with your PC
- When it’s done, disconnect, and Cydia is gone
