First time owning a modded OLED. Bought it from a modder on ebay. The console worked fine on Friday when I received it (5/26). Then I updated atmosphere and hekate and when I powered off the unit now I see the LED pulsate purple, then yellow for a few seconds, back to purple, then finally red before it booting me to OFW. Removing the SD card and booting the device just shows black screen too. I tried booting while holding - or + and still same LED sequence. Any thoughts on what could be the issue?
