In conclusion, and after waiting weeks to receive all new wall chargers, USB-C cables, HDMI cables. Is that, for whatever reason, the VIM 3 will not display an image onscreen without power supplied from the computer. Keeping cables unchanged but from 4 different wall chargers. Then rotating through cables to test the cables. Then rotating HDMI cables… showed only a black screen.
Then, when it is powered by a computer it will only display, as before, until it has reached or just finished the boot screen in android and krescue, or at a specific point at around 6 secs into ubuntu… then it will turn off; however now, in android, it will try rebooting, and make it to the logo screen and stop there indefinitely.
Only twice have I managed to get it to boot into krescue long enough to use the OS, and nothing I’ve found (though I’m admittedly an amateur at all this) seems to indicate the root cause of these issues; so I think I’m just going to have to send it in under warranty, as these issues are beyond me and have gotten in the way of enjoying trying to use the device
