I just received a VIM3 4Gb, I tried to Upgrade via USB-C cable according with
the instruction at this link https://docs.khadas.com/vim3/UpgradeViaUSBCable.html
I am using Windows 7 operative system and all the steps (1 to 4) were successing.
I flashed the “VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_EMMC_V20191231.img”
I tried to power VIM3 with a socket power supply of 5v 1.35A, but nothing happened just the white led went on, then I tried with a power supply of 5V 10A still nothing happened just the white led went on.
I was expecting VIM3 to boot Ubuntu, but on the video I see nothing at all.
I did another trial and flashed an older image
