I have SX OS and I tried updating my Switch using Choidujour to the latest firmware. After selecting Reboot Now, it flashed the SX OS logo and then the screen went black. My Switch is 100% charged. I tried to put the SX OS dongle in the Switch but it doesn't light up anymore. I tried to charge the dongle and still can't get it to light up or turn on the Switch. What to do?
