Hi,
I'm trying to update my Raspberry Pi 3B+ to run LibreElec 10.0.2. I've been running 9.8.2 with no issues for quite a while, I just needed to add some resolution data to the config, and boost the HDMI signal for my tv to recognize it.
However, when I flash my SD card with the tool and the correct image, my RP3 doesn't boot and the TV just shows a black screen, not the rainbow screen. I've tried flashing it again, and with a different SD card. My KORE-phone app also doesn't show a Kodi Mediacenter online.
Does anybody have any idea what I'm doing wrong? LibreElec should just run with the SD card right?
