sukanime,
I have an M8S S812 with the WiFi and Bluetooth chip RTL8723BS and I am trying to find a full SD flash package to run OpenElec or LibreElec. Right now I am able to flash an android 5.1 ROM and everything but WiFi and Bluetooth work...and I could really use help!
I have been trying to follow what you mentioned about compiling drivers with the kernel header but I am totally lost. I have Ubuntu and Windows and all of the equipment except for an OTG.
Can you help please @sukanime?
