Problem description: The signature was successful with AISI assistant, but the prompt "Installation package failed to verify or the device did not escape" was kept during verification!

Solution:

1. Make sure the device udid is ok first, and then see what system it is. Some IPA packages do not support the installation of devices above iOS 15.0.

2. Please check the application with cloud icon on the device and delete it manually (this will delete the application data), or reinstall the application with cloud icon first.

3. It may be that the device identification used for IPA file signature is inconsistent with the currently installed device. For example, an IPA file signed with the A device ID cannot be installed on the B device. If the installation package does not support it, only the installation package can be changed.
