Xolo TW800 factory reset via stock recovery topic

I have accidentally got my Xolo Play tab 7.0 TW800 locked. My nephew tried various pattern combinations and landed up locking it. Now it says enter gmail details to unlock it. I tried entering the registered gmail address but it fails as I cannot switch the Wi-Fi on. How can I enter stock recovery and do a factory reset? Or any other way. The tab is not in warranty. Please help
