I'm not sure what file DMS Doctor is trying to find, but it won't be the bin file.
Somehow we are getting wires crossed, so could you do the following for me?
Please
download the tools located within this thread, install them, run them and then:
Click on DMS Tools mode
Select your DMS (if not selected already)
Select the appropriate firmware (if not selected already)
Ensure the option 'Install non-hacked firmware' is checked
Uncheck the option 'Reflash box'
Click on 'Update Firmware'
Once complete then click on 'Boot Check', you will get told that a file has been put on the DMS.
Eject the DMS and put it in the car. Start it all up. Give it a few minutes, bring the DMS back to the PC and run the DMS tools again.
Click on 'Boot Check' and then please tell me what it says.
