Hi, thank, I forget this method. new result... same with 6.18.37: With 6.18.10-current-rockchip64 and rk3399-kobol-helios64.dtb-6.18.18-opp dtb file, Ok With 6.18.37-current-rockchip64 and overlay helios64 patch with armbian-config, Ko With 6.18.37-current-rockchip64 and k3399-kobol-helios64.dtb-6.18.18-opp dtb file, Ko more information: On "Cold Boot": System blink red After "Reset": Same crash like without DTB on previous Kernel like 6.18.10... I try edge with 7.1 kernel but not compile, finish with error during process. Back to 6.18.10 with dtb file patch and freeze with this stable config and kernel for this time, I don't have time to investigate more at this time. Have a nice day

Thank you very much. Thanks to your detailed guide—as well as the one by "Chiều Nhạt Nắng"—I successfully installed Armbian on my TV box. I had struggled for a long time previously, following outdated instructions without fully understanding them; I kept unplugging and replugging the power cable, which ended up damaging the power IC (so now I have to use the USB port for power). However, thanks to your specific guidance (user 0757), I followed the steps and finally succeeded. Thank you!

Honestly, I've already forgotten what the problem was there. Most likely, I used the Armbian installer and specified where to install the distribution in the automatic image download mode. Before that, I had tried writing it manually. Besides that, I found an important nuance — if you install software through armbian-config, for example GNOME and Chromium, the Plymouth splash screen will be automatically configured at boot, and hardware video decoding will be enabled in the browser, which for some reason does not get enabled when installing manually.

Can I ask how did you fix it? I have the same problem but cannot get it to make it work.

moved to off-topic neither a supported device nor about Armbian.
