A Summary of FAQs about the IPA Signature Function of 3uTools

It’s also known as “personal signature” when Apple ID is used to sign IPA files. The following list outlines some of the issues that may arise while utilizing 3uTools with the IPA Signature.

Is it necessary to jailbreak in order to install signed software?

No. The device does not need to be jailbroken during installation, whether it is signed with a certificate or an Apple ID, and it has nothing to do with jailbreak.

Is it necessary to disable two-factor authentication on the Apple ID used for signing?

No. The Apple ID with two-factor authentication turned on, may be used to sign IPA documents whether it is turned off or on; however, the Apple ID with two-factor authentication enabled must be confirmed the first time it is used, and it does not need to be verified again the next time.

What is the duration of the Signature’s validity?

The use time after installation of IPA files signed with a certificate is determined by the certificate’s validity period. The program will not be accessible to open if the certificate is revoked within the validity term. It is often known as “sign off”

Does it support batch signing? 

Yes. Batch signing is supported by IPA Signature. After importing, double-check the file that has to be signed, choose the certificate or Apple ID that will be used to sign it, and then click “Start Signing.”

Is it possible to install the Apple ID-signed IPA file on other devices?

No, it isn’t possible. The device ID is connected to the Apple ID-signed application. The signed IPA file cannot be installed on the B device if the device ID of the A device is chosen while signing.

Why isn’t the device’s signed installation package installed?

Currently, there is no automated installation option for the IPA signature tool. You must manually “open the signed IPA location” when the signing is done, and then double-click to install it with 3uTools.

What is causing the IPA file to fail to install and prompt “iDevice Unjailbroken”?

The device ID used to sign the IPA file, does not match the device that it has been installed. The A device ID-signed IPA file cannot be installed on the B device.

When the IPA file is properly signed and put on the device, it still says “The device is not jailbroken.”

Please verify the App with a cloud icon on the device and manually delete it (or use the 3uTools Toolbox’s “Delete Invalid Icon” to delete) before reinstalling it.

What should I do if I make a mistake when signing?

  1. The Apple ID account information is wrong; please double-check the account or switch to a different Apple ID.
  2. Please double-check and try again if the Apple ID password is wrong.
  3. The maximum number of signatures has been achieved. Each Apple ID may only sign ten installation packages in seven days, according to Apple’s rules.

Please try again in 7 days or change your Apple ID.

  • There was an error retrieving iCloud data.

Download and install the iCloud client from the iCloud official website. After the installation is complete, sign in to the iCloud client with your Apple ID once, then sign in again.

Note: Please download from iCloud’s official page. The signature will still prompt “Get iCloud data error” if you download iCloud for Windows from the Microsoft Store.

If you see the above problem, make sure you have the most recent version of iTunes. If the problem persists after updating to the most recent iTunes version, please switch to another Apple ID that may be used for normal login to finish the signing.

What does it imply when the popup says “IPA package does not support encryption”?

The App Store’s IPA files, as well as other encrypted IPA files, cannot be signed and installed again.

You’ll need to re-login to your Apple ID in iTunes in the following two situations:

  1. “Certificate application failed: Init anisetteData failed”.

If you get this message, log in to the Apple ID you’ll be using to sign in to iTunes, then reopen the 3uTools IPA Signature tool and try again.

  • Please open the iTunes installation directory first and delete the adi folder (the default directory is C:\ProgramData\Apple Computer\iTunes\adi). 

After removing, restart the 3uTools IPA Signature tool and try again with the Apple ID that needs to be signed on iTunes.

How to log in to iTunes: open the program on your computer, go to “Account,” select “Log in,” and enter your Apple ID account and password when requested.
