I had been using Hipstreet Titan 2 for the last 4 years. Last year the glass of my tab had been broken by me mistakenly. I fix my tab's glass yesterday. But i forget my pattern. It was not being used for the last one year. So i don't remember it's pattern. Now i want to flash my tab. There are no important data included in my tab. So i can handle the removal of my data on the tab. So, please help me to flash my Hipstreet Titan 2 tab.
