Hello everyone. A few days ago my MK808b stopped working. At one point I was on the screen and an ad appeared saying "updating the android system", or something similar. After a while, the system was restarted. But it never starts again. It got struck at the beginning and after 15 minutes of waiting, I decided to disconnect it and reconnect it again. The problem was that it never started again. Nowadays when you start it, the Linux penguin's are shown for a few seconds and then the screen gets black. I tried to enter the hard reset mode by I couldn't. I press the button as it is shown in the tutorial, then I plug the stick to the pc/tv but it didn't enter in flash mode. I have seen on youtube a video about how to get into flash mode, you press the button and then connect the stick and that's how I do it. I notice a difference between the youtube video and what i do, and it is that even having pressed the button, as soon as I plug the otg cable on the pc, the blue light turns on. But on the youtube video while the person is pressing the button, the blue light is not on. It turns on when the guy stop pressing the button. I guess there's the problem. I've tried two different USB cable and have had the same result. I also tested on the PC and the TV. I do not know what else to do. Can anyone help me to solve this problem? Thank you very much!!!!
