If you look now, you can see that a Model 3 in California with HW 2.5 was downgraded: https://teslafi.com/firmware/
Is this common?
Are you sure that it could not be a typographical error?
Got to be a typo. Only 2019.7 was 11, no 107's issued.
There are frequently apparent downgrades on teslafi.com which I've always assumed are logging errors, getting the versions backwards somehow.
My SR+ has this version (2019.7.107). It was delivered 2 days ago in Hamburg, Germany.
That firmware ( 2019.7.107 ) is for HW3, if I'm not mistaken. Perhaps an upgrade of hardware is in the HW 2.5's future?
