Impossible to execute command [the application revision '30085' doesn't match the installed software revision : '30084']
```

I haven’t had this problem before, and I don’t know what’s causing this. I can update devices that currently have older software version (\< 30084), but not the 30084’s

Hi,  
which module are you using?  
Are you downloading FW or any application?

Thanks,  
Alex

I checked for one of these devices:  
Firmware: OASIS SL6087 - vR7.52.0.201306260837.SL6087  
I’m trying to install an application:

```auto

Hi,  
Can you make sure the W version available in the module and the FW version in which the application build are same?

Are you downloading via AVMS? which application are you downloading? Any SDK sample ??  
What is the FW version of your module?

Thanks,  
Alex

The application is built for firmware 7.52.0, the firmware of the device is vR7.52.0  
I am downloading via AVMS, a custom application (so no SDK sample).

Kind regards,  
Jorn

Hi,

Seems some issue with the memory on the module side…

can you please share the logs from developer studio through CRM.

You have to raise a ticket with sierra wireless with the help of your distributor/FAE.

SWI can then analyze the logs…
