I tried to install LeJos on my EV3. After multiple fails (because of wrong Java version etc.) it worked, once
Then i restarted it and the normal Lego UI was showing. I formated the SD card again and created a new one using the tool from LeJos. It was starting again the LeJos software and updating everything, but during "expand image" the ev3 just turned of and now i can't turn it on again
I already removed the sd card and changed the batteries, but there is no sign of life, not even a LED blinking.
Was somebody already having the problem or can provide me a solution, I would really appriciate it . (The Lego support was not able ATM)
