Hi everyone. Sorry, I cant speak russian. I get a mmi3g into my shop and try to diagnose it. It powers up but have no sound, no tuner signal and no media music play. I boot into normal mode and get this log but cant figure up what is happening. I attach my logs. Can anyone enlighten me.
Thank you ...
