The A95X-F3 has an upstream device-tree file (authored by me) so the current AMLGX image is usable; with caveats that accompany G12A/B and SM1 boards (read the LE11.x release notes for the info, nothing changed). Read the Amlogic page in the wiki for install instructions: https://wiki.libreelec.tv/hardware/amlogic.
WiFi and BT won't work due to the MT7668 chip having no upstream drivers. The FireTV driver from the kernel mailing list Q&A is here: https://github.com/chewitt/MT7668 but I could never get it to compile in a usable form. Hence the repo is untouched and I archived it a while back to drop a hint to people that kept cloning the driver and asking how to compile it. I had a brief look at the ophub driver and that looks similarly bad to the one I found before. The guy that "figured it out" doesn't sound like he really figured it out either. I can't see an email for him, but his name is reasonably destinctive and Google shows the same name associated with some postings to kernel and freedesktop related things so he's probably traceable if you ask around.
I never looked into LED lights on those boxes either. The clock display might be do-able but for the light ring .. I'd need to see the original Android dts file or decompiled dtb to comment further.
