I have a problem with my Yun, it works to upload sketches but the Linux part I think it's broken. I do not see any LEDs on when I plug the YUN in USB. So I tried the steps from the following link https://www.arduino.cc/en/Tutorial/YunUBootReflash , but after I press ``reset and enter, I receive something like this
So nothing readable. Is my Yun Gone or I can make it work, somehow?
