[swaroop_singh]

On 27th Evening I entered wrong patterns in my Karbon ST10 Tablet for experience purpose and finally screen has locked.
Now it is asking me to sign in with google account and the problem is that
1st How to SignIn with google account without internet connection. Even Tablet has dongle support but without entering setting how I will connect it with internet ? I have try it out but didn't able to connect with internet.
I have called Karbon service centre but he told me that pattern lock don't fall under warranty so service charge will be charge which is 250.
Please tell me what I will do ??

You can't do anything but return it to factory settings, which will cause you to lose all your files and apps.
To do so,
Hold the volume down and power button together, go to recovery mode and do a restore.

Karbonn guys will reset the tablet. Its better you do it yourself by following thetechfreak's advice.
