Oops.. no internal install ?

Very new to this… now i understand CoreELEC is installed on same boot stick ?
This explanes why it crashes when exange for movie filled usb stick…
without the boot stick CoreELEC doesn’t run ? have only few usb ports on my X96 Max 4/64GB box… Stick gets very hot btw…
Please give some tips how to go further, in the first place my thought were that my box was internaly flashed, not the case i now understand, have network working, Bluetooth is not working, although it is switched on, wifi will not log on, but this is also the case with the wifi on my (LibreELEC) NUC, Bluetooth does work on that NUC, only changing display prefs makes that one crash…
I will try LibreELEC on a Rasp.Pi4B 4GB… for which i have DVB hat for…
Praise for the CoreELEC developers ! the android version seems a bit flakey for now… long live CoreELEC !

installtointernal is not supported on newer devices that use the newer kernel.
You can get a micro SD card, and run CE from it, that will leave all of your USB ports free.
