I am using Karbonn A27+ and today my Cousin locked it by attempting patterns lock more than 5 times. So, it was asking for email address and password of the google account attached with my android phone. But, the problem was it has disable the data connection though it was not able to authenticate the lock.I had search a lot of hours on internet to how can I unlock, I found many tricks on how to unlocked android phone without internet connection....
