Garmin Edge 1000 rebooting loop

My Edge 1000 suddenly started endlessly rebooting a day or so ago. I’ve had a good search for any resolution and found that while it seems to have been a known issue for some time, Garmin appear to be largely ignoring it.
Has anyone got any tips?

Hard reset? lap/reset and power button held down I think?

Or plug it into a PC? Sometimes that fixes things.

You can send things back to Garmin and they’ll send you a refurb unit for a cost. You still end up with a garmin so it’ll be buggy 🙁

My 810 totally freezes sometimes and I have to do a hard reset by holding the bottom left of the screen and the power button down for a number of seconds and it’s all fine again….until the next time.
