I'm really guessing here, but....
These builds are pretty much directly off the karma source. Which would explain, I guess, why I can't sync my empeg over ethernet. I have to use USB to get a sync to complete.

I'm hoping, it’s the same bug that is causing the karma to timeout during ethernet syncs.

Either way, try syncing again with emplode 2.10 via USB.
Let us know if it works.
