Abstract: The present invention relates to a method for updating a firmware on a device, from a current version to a new version, said firmware being split into: —a core part, —an extended part comprising a plurality of entry points callable by the core part, said method comprising: —inhibiting the entry points between the core part of the current version, called current core part, and the extended part of the current version, called current extended part; —erasing the current extended part; —downloading the core part of the new version, called new core part; —erasing the current core part; —downloading—the extended part of the new version, called new extended part; —activating the entry points between the new core part and the new extended part.

Abstract: Modification of the execution of a platform-independent first method of an application within an integrated circuit card having a first non-volatile memory, a second rewritable non-volatile memory, a virtual machine and a processor unit, wherein said platform-independent first method includes a first operations sequence and a second operations sequence. Checking if there is a call within said platform-independent first method to a specific second method, having one parameter; —if there is such a call and if said specific second method is not platform-independent, checking if there is an alternate function associated to said platform-independent first method stored in a memory of said integrated circuit card; if there is an associated alternate function: executing said alternate function to replace said first operations sequence; executing the second operations sequence of said platform-independent first method; otherwise executing by the first operations sequence and the second operations sequence of said platform-independent first method.
