My bios ME is still 188.8.131.528.
The LED EC1 FW was updated to ...0202.
U have to update the mei module to 184.108.40.2062 but inbios mei in 0504 is 220.127.116.112. So u need the specific mei module update files which aren't available at Asus Encore page, but if u wish I can link them to you.
This 18.104.22.1682 version is for new cascade lake x, but if u have a 7xxx or 9xxx cpu, ud better update to 22.214.171.1242 since the new 126.96.36.1992 doesn't cover some vulnerabilities in these older cpus.
