Thanks for fast response. There is no way to reach to manufacturer. They do not respond. I keep on trying for over a week with no luck.
So what is exactly a hard reset? Will I lose the operating system on it? Why I'm asking is I'm not sure if I can install an operating system back on it or not. But if I lose only the files and applications I've installed on it, then it's OK with me. I can do a fresh start with it.
How can I initiate a hard reset? There's nothing on the manual
