Didn't work for me, but that's probably because I destroyed the kernel with trying to fix stuff I have no clue of. At least the display recognized that a device is attached to it, which wasn't the case before. So I hope it's fixed for the other guys that reported and waited (I think I'll do it that way the next time). Anyway, thank you very much for looking into it and of course providing these nice Armbian images to us!

I also experienced this problem yesterday. Update&upgrade -> reboot -> no HDMI output, red and blue LED solid on. The network interface LED starts flickering like an HDD LED, but after a couple of seconds it is being turned on and off with maybe 1.5s delay and nothing more happens. Since I'm not the "deep into Linux" guy, I googled my ass off for a couple of hours, tried fixing things, upgraded my device to the dev kernels and uboots and I have no idea what else I tried (it was 4am in the end ;-) ). I did all that chroot'ing into the USB mounted SD HC of my original system after I set up a different SD HC with a fresh armbian installation and probably fucked up the whole original installation, but I learned a lot. :-) Could someone please explain in a short version how I can downgrade the system to 5.35 to check if I completely messed up or if it at least boots? Upgrading wasn't a problem, since I could just use the kernel packages provided by the Armbian page, but I'm to dumb to find the ones to downgrade. Btw: Here's the update history from yesterday before everything went wrong (maybe it helps): Upgrade: libgcj16:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libgcc-5-dev:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), gcj-5-jre-headless:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), linux-image-odroidc2:arm64 (5.35, 5.38), cpp-5:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libitm1:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libvdpau1:arm64 (1.1.1-10~armbian5.35+1, 1.1.1-10~armbian5.38+1), libasan2:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), gcc-5-base:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), gcc-5-base:armhf (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), gcj-5-jre-lib:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), armbian-firmware:arm64 (5.35, 5.38), libstdc++-5-dev:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libubsan0:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), g++-5:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), sunxi-tools:arm64 (1.4.2-1~armbian5.35+1, 1.4.2-2~armbian5.38+1), gcc-5:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), linux-u-boot-odroidc2-default:arm64 (5.35, 5.38), armbian-config:arm64 (5.36, 5.38), libgomp1:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), hostapd:arm64 (2:2.6-4~armbian5.35+1, 2:2.6-4~armbian5.38+1), linux-dtb-odroidc2:arm64 (5.35, 5.38), libatomic1:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libcc1-0:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libstdc++6:arm64 (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), libstdc++6:armhf (5.4.0-6ubuntu1~16.04.5, 5.4.0-6ubuntu1~16.04.6), linux-xenial-root-odroidc2:arm64 (5.37, 5.38)
