OS fails to install properly with OOWOW

VIM4
1

Which system do you use? Android, Ubuntu, OOWOW or others?

Using OOWOW to install Ubuntu, Armbian or Android fails to properly reboot into the new OS. I am connected via HDMI using a directly attached keyboard and mouse.

I just got my VIM4 a few days ago. It had some version of Android installed which booted fine. Since then, I have attempted to install a different OS (Ubuntu, Armbian and Android) but without success. The screen remains blank when I reboot. When trying to boot into the newly installed OS, the device successfully requests an IP via DHCP and can be pinged, nmap takes a very long time to complete and shows no open ports.

Have I forgotten to flip a switch somewhere? I am following OOWOW getting started [Khadas Docs] (OOWOW Wizard) The LED is solid white.

I discovered the rescue shell in oowow, very nice! It seems I am booted in some variant of OpenWRT.

Hello @laibsch

Does it report any errors when you install the OS ?

Thank you for the fast response, numbqq.

The flashing completes successfully and without any error message. I also verified the download by clicking on the appropriate button although that came back a bit suspiciously fast.

Hello @laibsch

Could you try to press FUNC + RESET to boot to oowow and reinstall again ?

sure, but that’s what I did three times in a row now and without success so far.

Hello @laibsch

You can also try to use usb flash tool to install the OS.
