if not, go to step S202; if yes, the process proceeds to step S203.
S202: executing a software rollback operation;
in a specific embodiment, the software rollback operation is performed as mentioned herein, which may specifically be:
deleting the file links of the newly added files in the software installation directory, and recovering the file links of the deleted files in the software installation directory.
S203: judging whether the current version number is consistent with the version number corresponding to the software upgrading packet;
if so, the step S204 is entered; if not, the process returns to step S202.
S204: and confirming that the software upgrade is successful.
Optionally, after executing the software rollback operation, the following steps may be executed to determine whether the software rollback operation is executed successfully:
judging whether the current version number of the software is received in a second preset time;
