@JCBERLIN....many of us have downgraded to 1.1.6 so don't be afraid that you will have an unstable camera or lose some functions. Check the 1.1.8 firmware release notes here: https://www.canon.com.au/support/support-news/firmware-updates/eos-6d-firmware-update-version-1-1-8 and unless you are in this specific situation you should be just fine.
