hello,
I just got an N2+.
I'm used to raspberries, but i start on the N2
LibreELEC-AMLGX.arm-10.85.0-odroid-n2.img.gz i know what to do 
But ... u-boot.bin-odroid-n2 
what do i do with this file ?
someone has a link to a tutorial to start from an N2 from scratch ?
Thanks
You write the image to an SD card (same as an RPi) insert the card to the board (same as an RPi) flip the switch on the front to the right so it ignores petitboot (which does not support extlinux booting) then power on the board. There is nothing to set and it should boot straight into Kodi.
NB: You will probably want to turn hardware decoding off on the N2 (same as all G12A/B and SM1 devices). H264 works well but HEVC isn't so good and anything 10-bit wedges the board.This does limit the board to 1080p, but it works well. If you want 4K support you will need to run a vendor kernel image like CE.
4K requires hardware decoding which isn’t going to work on an N2 due to current issues with the upstream decoding drivers. You’ll need to use CE on the Amlogic vendor/legacy kernel. I can’t say whether that’s laggy or not as I don’t use or track CE (and not that I find RPi4 slow either).
