I've got an LG G watch. Rooted and rommed with Gohma 2.3

All is well with the rom itself, BUT - when I connect my phone (GN3) to the Internet, for any length of time, the watch gives me the notification "update download; swipe left to install". Ok, fine. I swipe, and wait. Only it doesn't install. It stops, then gives me "cannot install/error 7", and forces me to reset. I reset/restart, and the cycle continues.

This has been an issue since Jan some time, and I had Gohma 2.2 installed at the time. I've tried installing the update zip file (via adb), but that hasn't worked, either. I can BRIEFLY dismiss the notification, but it pops up again, after about 10 minutes.

Thoughts?
