After trying to flash my Beaglebone black C with Ubuntu (Loaded the image using PiFiller on a Mac) and power suply (5V), and having many failed attempts finally after a around dozen tries the 4 LEDs didn't light anymore, only the power led. I already tried pressing the S2(boot) button for a few seconds alone, and in combination with the reset and power buttons and nothing work.
Do I have a BeagleBRICK?
