BC127 Downgrade to V5R11

[jabrane1]

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

BC127 Downgrade from 7.2 to 5R11

I am using BC127 for a project using the old version of Firmware V5R11, All the code was running corresponding to this version. I got made an update to one of my device and discover that the new AT command for the version 7.2 is different from the V5 and I need to use a tool for downgrade because the Melody DFU V5.0.0 block the downgrade. What I can do and thanks for your help

Thanks
