Hi,

I’m trying to do the firmware update released by Hologram, which according to this post([https://community.hologram.io/t/updatin … eld/3562/5](https://community.hologram.io/t/updating-the-cat-m1-r410-on-sparkfuns-shield/3562/5)) has worked for them. I was stuck at the same place- could open sockets, but could not connect to TCP socket to communicate with Hologram cloud. Hologram released a firmware update for their board, the Nova, but it seems like this update might be able to update the ublox R410 on the Sparkfun shield as well.

Anyways, I connected the VUSB\_DET jumper on the back and made sure it was shorted, then tried to connect it to both a Raspberry Pi 2 and my windows desktop to try to push the firmware but both devices were not able to register a connection. After holding the “POWER” button on the shield for a couple of seconds, the shield(/modem) shows up on my device list but right away toggles off again.

Was anybody able to communicate with the shield via USB?

Are you trying to use the Nova firmware update to update the Sara module? That will not work, two different modules
