I have the same problem as from this morning - one lighthouse blinking red and no error message. I have the pro and 2.0 lighthouse, looking at this thread it seems as though this is now a common problem and you are asking all customers to return their devices? I have owned my vive for lass than 2 months. If the hardware is unstable it should be recalled and taken off market until a relaible fix is in place.
Please contact me with next steps.
