Micromax Funbook P600 tablet - stucks on boot screen

Hello friends,
I am having Micromax tablet which I'm using since few weeks. The tablet was working well sinse then. The problem raised when I tried to update it to android jelly bean. I did it successfully it was installed as I was thinking. But when I reboot the system it’is stuck on boot screen.
Cn't find out how does this happened? Where the thing really went wrong?
Can anyone here help me regarding this issue?

Hi there

I think you should remove the battery of the device when it got struck while restarting.
And then let it be switched off for 5 minutes.

After 5 minutes , reinsert the battery and then try to switch it ON.
As soon as it start over, RESET it to FACTORY DEFAULT.

procedure is :-

setting-privacy-factory reset
