After updating to iOS 11 version, many iPhone/iPad users were not able to sideload any apps onto their device through Cydia Impactor. If the same issue happened to you, you should stay calm as it’s not your computer  acting up.

There has been thousands of discussions talking about this issue in iOS 11when using Cydia Impactor. Finally, the final conclusion is that the tool is currently not compatible with any version of iOS 11, though it’s still in beta stage.

When sideloading the IPA file on the iOS 11 iPhone/iPad using Cydia Impactor, there will be a message saying “lockdown.cpp:57. LOCKDOWN_E_PLIST_ERROR”.

So, in this post, we’ll show you three common ways to fix Cydia Impactor not working on iOS 11.Some of them are the replacement for Cydia Impactor.

Method 1: Downgrade back to iOS 10.3.3

That’s the first thing you should do! If you don’t do it now, Apple may stop signing soon. iOS 10.3.3 is now still available for you to downgrade.

Here are the reasons for you:

  • iOS 11 is not currently very stable as it’s still in the initial developer beta, so there are still tons of bugs .
  • Both iOS 11 and 10.3.3 don’t have the jailbreak tool, which means you can still remain the compatibility.
  • You can upgrade to iOS 11 at any time you like or wait until the Cydia Impactor is compatible with working on the new firmware.

Method 2: AppValley

Like Cydia Impactor, AppValley also allows you to install the tweaked app on your iPhone or iPad without the jailbreak.

There is only a difference coming from the signing certificate. If you use Impactor, you will need to sign the app with your Apple ID, which usually expire after seven days. But with AppValley, it could be more.

The benefit of this app is that you can install it directly on your iPhone/iPad without using computer. Simply visit here  and tap on “Install AppValley.” If the app is unable to download, you can visit other similar sites such as IPASigner.io.

You can use DanTheMan827’s iOS App Signer tool accompanying  with Xcode to create the IPA file and then sideload it on your iPhone.
