Hi there - my new VIM2 only had Android on it and I want Ubuntu so I prepared an SDcard and tried to boot into upgrade mode as per the instructions here.
About when I pushed the reset button the screen went black. When I released the power button the screen stayed black - no upgrade/progress nothing. White LED stayed on. After a while tried removing power and plug in again - still only ever black screen & white LED.
I have tried the M-register mode as per this thread with the same outcome - screen stays black, white LED stays solid. (I presume the instructions are short M pins, press & release reset button, then remove short from M pins?)
Any/all suggestions welcome as cant get my VIM2 to do anything now
