Comfort Automation/ Security System Forums

Just spotted this thread and it sounds pretty identical to the issue that I had a couple of weeks ago (mentioned on another thread) - essentially a UCM/ETH03 upgrade of the main UCM firmware which then corrupted the UCM and I was no longer able to connect to it.

I didn\'t have the benefit of having another UCM so mine had to be sent off to Laser to be re-flashed.

slychui - Could there be a bug with UCM/ETH03 firmware upgrades if that is two of us that have ended up with the UCM/ETH03 in same state?

This was due to the ETH02 submdoule. It is not able to upgrade its own UCM, so yours is not ghe sae issue
