I used the search function to find an answer to this but no luck.
I am trying to upgrade the factory Android on my VIM3 to the latest version to get touch screen support etc. but after having tried all 4 ways to enter upgrade mode I am stumped. I ran the various tools/burners etc. and followed the instructions but nothing I tried will initiate upgrade mode.
When using the USB upgrade mode should I also connect the VIM3 to 12 volt external power? I’m a bit nervous about doing this as I don’t want to burn the board.
Any info./help is appreciated.
