Hello guyz, Just got MRZ02, when I started it up the screen went black with some japaneese letters in the center an number 6 in the righ bottom corner. Started looking in the forums to find out the problem. I came accross a video on youtube from a Russian guy who solved thr problem bu deletin the system file and replacing it with the new one. I did it accordingly but the device still doesn't work. only thing that has changed is number 6 which turned into 7. Any suggestion?
