After uninstalling NobetaAlert plug-in, you can use Unc0verb36 version to escape from prison.
Download the old versions of Unc0verb29 and CydiaImpactor on the computer, then install Unc0verb29 with CydiaImpactor's self-signature, and uninstall the NobetaAlert plug-in after installation.
If other shielding plug-ins (not profiles) are installed, it is best to uninstall them at the same time. Please refer to the self-signed installation of CydiaImpact.
