LG C4 can't detect Dolby Vision from Ugoos AM6b+

Sorry, one more thing:

When I sshed to ugoos, the current folder path is “/storage” and there is NO “dovi.ko” and “remote.conf” files in that directory, neither do they in the “/” directory. Is that the reason? Should I follow the instruction ([Guide] S922X-J (Ugoos AM6b+) CoreELEC installation and FAQs) and do it all over again?

Update: I found them under “/flash”, is this normal?
