Upgrade firmware SW4016 from v5.0.4 to v6.2.2f

[Anonymous]

Hi:

I need to upgrade frimware in SW4016 from v5.0.4.

I think the firmware upgrade process step by step, is as follows:

v5.0.4>v5.2.0>v5.3.0d>v6.0.0b>v6.1.0a>v6.2.2f

I can not update it from the console, I get the following error:

Could not read the Pfile headr.

Firmwaredownload failed. (0x12) Cannot access package list (.plist) file.

Can you please confirm us the commands?

Kind regards

when upgrading in the earlier versions of FOS you have to specify the exact path to the extracted firmware image with the /release.plist appended to the end of the path statement. So \v.5.2.0\release.plist
