BC127 Downgrade to V5R11

I am using BC127 for a project using the old version of Firmware V5R11, Is there anyone have this version. I searched in the Sierra wireless website but without success.
Many thanks,

Hi @jabrane1 ,
The FW is very old so that it doesn’t exist in source page anymore. You can contact Matt who performed downgrade to V5R11 2 months ago as the below topic. He might store the FW locally
