Those are literally the steps that I did to code mine after putting in a used trans from a 2009 335xdrive to my 07 335xi. I verified in the UIF of INPA before the flash that it said the other cars vin for the transmission ecu and after the flash it had my vin in the UIF. Only after doing that my car behaved normally and displayed the correct gears on the dash.
