Zusammenfassung:	The invention relates to an electronic device and a software provisioning server. The electronic device is configured to obey an Anti-Roll Back, ARB, enforcement policy, obtain an ARB exception associated with a software, wherein the ARB exception comprises a signature of the ARB exception and a revision number of the software, check the validity of the signature of the ARB exception, and execute the software having the revision number so as to overrun the ARB enforcement policy if the signature of the ARB exception is valid. The software provisioning server is configured to determine an ARB exception associated with a software for overrunning a ARB enforcement policy in an electronic device, wherein the ARB exception comprises a signature of the ARB exception and a revision number of the software, provide the ARB exception to the electronic device.
