After performing above steps given as correct answer. I can able to install latest os version in my device. In computer the software show installation complete message. But when I switch on my device after loading for some time I got dialog box which has some unknown language messange written in it. After that I press dialog box button and again my phone get restarted and start performing same thing.

Again I want to mention one thing that when I get my device after update at that time my device does not have any bettery so it can't turn on. After some recharging I turn on the device and got above thing that I wrote in above paragraph.

Please some one help me in this.
