Abstract: A method and an apparatus for updating software loaded on a secure element, SE, which SE comprises an update agent handler, and an update agent. In a first step, a request to backup a current version of software loaded on the SE is received at the SE. The request is sent from a device, external to the SE. Upon receiving the backup request, the SE performs a secure backup of the current software version, and returns the software backup to the device, to be stored thereon. In a further step, the SE performs an update process of the current software version, to obtain an updated software version. If the update process fails, a rollback is performed at the SE to restore the software backup as a new current soft-ware version on the SE.
