Similar here.I got 6.5 last week and 6.8 this afternoon.
I've also had quite some difficulty in getting 6.8 to install.Similar here.
Unfortunately 6.8 has been ready to install for 3 nights and it still hasn't installed. I tried hitting install now, no joy. Threw a charger on my 12v battery tonight to see if that does the trick.
I cant even tell if that error code means High voltage not qualified low voltage low or high voltage not qualified level low.. lolI've also had quite some difficulty in getting 6.8 to install.
I checked the 12V battery SoC in the body control module with Forscan and multiple times I had started at over 80%, at least once with over 90%, and still no go.
Checked the info from the mmota details API Endpoint that gets loaded when visiting the vehicle dashboard page on the Ford website and every time it's been reporting the error as InhibitRequiredHvNotQualifiedLvLow.
I haven't gotten the replaced battery monitoring sensor but maybe it's time to schedule that.
