Hi!, I have a Lenovo a6000 plus. Some days ago there was a lollipop update for it which weighed 1092 MB. But it was withdrawn by Lenovo as it had many bugs. So I could not update my phone. Yesterday again I got an update of 1124 mb and it seems that it is for lollipop 5.0.2. Is it a safe update? Should I go for it? Pls help me. Thank you.
