Hello Synety,

 

the attached picture is still in approval so I am unable to see what it shows but you should utilize the community FAQ as it contains this post here:

 

Oct 7, 2011 Question: How can I setup my Phone / Provisioning / Download / Upgrade / Update / Downgrade Software?
Resolution: Please check => here <=

 

Please always post the software versions that are involved.

 

Best regards

Hello Synety,

 

the picture still has not been approved so I cannot comment due being unable to see what is shown.

 

What software Version are you trying to downgrade to as UCS 4.1.0 is LYNC only.

 

Please bear in mind if your phone is loading the combined sip.ld it will have to download a rather large file.

 

If you have the split version of the sip.ld then it will only download its individual file which is the preferred method for slower networks.

 

You may want to consider to work with your Polycom reseller and/or Polycom support directly if you require further assistance.

 

Best Regards
