Webex Room Kit Plus Software upgrade from 9.5.1

[Juan Parodi]

I am currently trying to upgrade 4 Webex Room kit plus' to the latest revision software. The issue is that I received these devices brand new with version 9.5.1 loaded, of course the immediate followed versions are deprecated by Cisco, So I tried the oldest published 9.12.4 which is under 1 GB using the Web interface to the device but no luck. I setup IIS on a laptop and tried to upload the software thru SSH using Xcommands, no luck, then I received a Peer certificate cannot be authenticated with given CA certificates issue and a copfile signature verification failed, I even changed the .SGN extension to the .COP, no luck either. It is like 1 step forward and 3 back every time. I wonder if anyone can suggest a solution or if you have a step by step how to get it done document. So far, I cannot find anything effective that will get me to a safe version from which I can then upgrade to the latest revision. Can anyone assist?

I was able to successfully install 10.3.2 from the old 9.5.1 via the CLI. I first striped away the signature (.SGN) using a HEX EDITOR and then extracting the files from the Cisco .TAR file by renaming the file to .TAR and using 7ZIP to extract all files within the .COP file. Identify the main PKG file for the 10.3.2 upgrade (see below). Then from a SSH session used the following CLI command on the Webex Room command prompt.

xCommand SystemUnit SoftwareUpgrade URL: http://192.168.1.1/s53200ce10_3_2_0.pkg 

We have IIS running on a laptop (192.168.1.1) and we had to make MIME modification for .pkg file to automatically download when we were attempting upgrading against the original .SGN file. NOTE: I tried another version 9.15.3 but was unsuccessful.

@Juan Parodi What error are you receiving when you are trying to upgrade from the Web UI?

File size error. apparently it is too big, yet when I use an older file which is under 900MB, I get cop signature cannot be verified.
