CX5000 error 0X80004005 firmware update



We recently purchased a polycom from ebay as either used or new.


We noticed early on that the Panoramic and active video does not work well with the active camera often showing nothing on the other end and the panorimic showing a still image on either end of the call. We are using skype for business (2015).


After doing some research we found that the firmware is out of date and decided that the problem may be resolved by updating it....currently we are on V1.1.4030.0


This is a 2009 Microsoft model and when trying to update (by following the blog here: and other online sources we cannot upgrade the firmware or run any command using the managemnt tool. I'm aware that there is two versions of the managemnt and we have tried both softwares and got the same error. We should be using Microsoft RoundTable Management Tool with the firmware 1.5.4105.0 but it fails when running any command like


RTMANAGE.exe -m:img -i:eboot -f:cpueboot.bin (with the firmware files in the same directory)

Rtmanage.exe -m:diag -l:flush

Rtmanage.exe-m:cfg -r



We simply get 0X80004005 unspecified error.


We've tried other PC's both 32 bit and 64 bit, ensured were not using USB 3.0 


Nowhere online seems to be able to offer any indication as to what this error is and without updating the firmware we have no other ideas on this.


We have another polycom device which works fine and is two years newer and is also the non microsoft version.


Any help would be appreciated

Hello Dcotter,

welcome to the Polycom Community.

The RoundTable may look like the CX5000 but is a Microsoft Product and needs to run Microsoft code.
