If you have already installed lineage 15.1 why do you ask how to do just that?
My bad 
…I think maybe in the process I missed something regarding the black sides
So i have installed and editted 3 panels, huge thanks to @pgale for making this available for us to customize.
The big negative that i have with these, is that on all 3 devices, VLC media player is not playing audio from rtsp streams, and frigate cards that open with audio on, also do not have audio on.
I really didn’t want to be that person but I am a little stuck on the process
I have managed to flash to the device (thank god for that old laptop left in a drawer) but when I reboot the TSV the QFIL tool menu only shows these three options and not Partition Manager.
I have to assume I am doing something really daft and apologies if this isn’t the right place to ask
TIA
