I have been using my modded oled hwfly for a while, and the last time I restart the device was probable 2 months ago. Today, when I was trying to reboot the device, it did not restart, instead it flashes blue light for about 1 minute, turn white for 1 sec and blue for another minute, lastly flash yellow 3 times. I have no ideas what does it means, and hope if anyone can give me some helps, thank you in advance!
