According to https://github.com/redrathnure/armbian-mkspi?tab=readme-ov-file#technical-details the mks-skipr is just an mks-pi with an additional mks-robin-nano attached via uart. That should be the reason, why there aren't separate mks-skipr images, only images for mks-pi. Btw, the images for mks-pi and mks-klipad50 both use the same kernel. After replacing the corresponding .dtb file with the one from your original image, these images should behave identical. Your approach of dd'ing the image from a usb-drive directly to the system that is currently running, sounds as dangerous as replacing a car engine while it's running. You said, that you've successfully used rkdeveloptool for a recovery. If that means, that you have flashed a *full* image to the emmc this way, then I would use this approach to directly flash the desired armbian image to that emmc (without using any other usb drive). Or try to intercept u-boot from the original image to boot from an usb-drive (as I wrote here). Then you could 'dd' an image stored on that usb-drive to the emmc - but neither the source or the destination filesystem should be mounted/in use during that process.

I bricked my original H96MAX TV box while tinkering with it, so I bought a new one. The new unit works fine with both wireless and wired networks on Android, but after flashing the firmware Armbian_26.2.0-trunk.302_H96-tvbox-3566_forky_current_6.18.6_minimal.img, the wired network stops working and only the wireless network is functional. Please help me fix this issue, thank you!

Try this. It worked on radxa-e54c with Cinnamon. rm -rf ~/.local/share/cinnamon && sudo reboot

@Nick A Since both the A7a and A7z have the same CPU family, I made a build using the exact same options, but selecting the A7a instead in the compile menu. This build did start to boot, I saw the Radxa logo, then some Linux console boot messages (but it was scrambled on the screen a bit), and lastly I saw the Armbian logo and the spinning circle. Eventually that all went away and the screen was just empty. No response from key presses, etc., but my HDMI screen was still getting signal, it was just blank. I also tested different distros and versions available to see if that made any difference (ex. debian vs ubuntu, nodel vs plucky vs bookworm; etc...), non of that had any effect. So it appears, at a first start, to be a A7a vs A7z build difference to at least get an attempt at boot. Then the next issue is that it never fully reaches a usable OS console. Thanks!

@Bones558 I don't have a a7z to test with right now. I should be getting one soon and I'll look into it. I'm pretty sure a USB to UART serial device works.
