I want to install libreelec to internal after running it for a while from microsd card. Just curious if there is any difference in speed.
But if I install to internal, am i still be able to boot from microsd card if I insert a microsd card with a different version of libreelec? Or do I need to revert back to android first and than install libreelec on micro sd card the normal way (power+reset button).
I haven't noticed any speed different.
Yes, you can boot another (or the same) version of LE from SD card.
