Could you re-test with v154, and if it fails, try it at home with "force dc/car" enabled.. and look for a line of output on the serial port early in the boot sequence, starting with "fix_visuals():"..

Send me that line of output.

If you cannot find it, then you're (1) in Home mode, or (2) don't have the feature enabled, or (3) USCWOAP.
