I posted this in another thread but it was maybe not the right one as it got no response.

I downloaded the latest Snapshot.

My Heatermeter is currently running a cook. I saw the "AVR Firmware" tab on the "config, home, etc." screen. When I open it, it asks if I want to "Update" using one of the three listed methods it suggests. Can I just select the "Local Machine" and point it to the .img file for the Snapshot I just downloaded to my hard drive a minute ago? Will this update my unit?
