I just updated my 2018 m4 with the UPD9042.bin download with no issues. Not sure what exactly this update did everything seems to work the same. It only seemed to update the Phone and HMI and not change the media. wish I took a screenshot of the original version numbers but phone went up to 006.002.xxx and HMI went to 006.007.xxx. media same 006.001.xxx.
