@andarezta unfortunately i could not fine how to build dbt in order to fix PHY (error: -19) reported above in your youtube channel.
I found a video "T96 Pro amlogic S912 armbian everything ON" in which you already have network enabled on T96 box in which you are creating remote shell. In my case, GT1 ultimate does not see network.
Could you please share steps how did you build DTB to fix "Cannot attach to PHY (error: -19)" ?
