Can you please confirm from Tomi whether fw updated to 1.75.01 on this CFL m/c? AFAIR update was made on KBL m/c only.
Comment 5 Tomi Sarvela 2019-03-11 12:31:03 UTC
CFL-8109u doesn't seem to accept LSPCon upgrade. Error with bobcat is
testrunner@cfl-8109u:~/bobcat$ sudo modprobe i2c-dev
testrunner@cfl-8109u:~/bobcat$ sudo ./bobcat_isp -Run

Did you tried with Windows bobcat tool?
