Hi there, just installed this a few days ago. All appeared to be working well until I attempted to do the FW update yesterday. Put the folder on an empty SD card, went through the menu to the update, it then had a screen for a few minutes that said something like "Reading, please wait a while", then a screen appeared with some verbiage and a button to begin. Pressed that, it shut off, restarted, displayed the splash screen, then this lovely message:

Tried everything to get it back from resets to disconnecting power, with no luck. It's totally bricked, and there seems to be little chance of getting that SD card back out.
Not really sure what to do now. I imagine I could try to deal with them to get it repaired/replaced under warranty or just exchange it from the (online) seller, but of course there will always be the fear that it will do it again, perhaps on a future FW update when it's freshly out of warranty. Any suggestions? A web search doesn't reveal too much on this topic, and the manual's troubleshooting conveniently leaves this situation out.
