Proper OS upgrade

Is it neccessary to upload the w.dwl in the module after I upgrade the OS? For example, I’ve uploaded the file 657g00_full_q24pl002.dwl in the module and restarted it. Now I see that the OS version is 6.57g. And the module works just find. And also I cannot find the w.dwl in the firmware catalog. So when should I upload the w.dwl?


there is no need to download the w.dwl file after the 657g00_full_q24pl002.dwl as it is already included inside.
This remark is applicable to any “<FW_version>full<WCPU_version>.dwl” file.
