By the help of the user @tomergam it was possible for team CoreELEC to finish up a Amlogic-ne 5.4 generic image where WiFi and JL2xx1 Gigabit Ethernet. Please use sc2_s905x4_4g_1gbit.dtb for this device.
Please feel free to have a short test of the new era CoreELEC image:

Remember: Upgrade from Amlogic-ng to Amlogic-ne is not recommended! Please use another spare boot media to not interfere with the old installation.
