Can't hard reset samsung and forgot the Pattern I have Samsung Galaxy Duos Grand Prime plus running Lollipop. I forgot the pattern.


If I keep entering wrong pattern, the phone won't prompt me to enter
the backup pin
Volume up + home + power isn't working, the phone will boot normally. Volume up+ power isn't working either.
Volume down + home + power takes me to the downloading updates screen and it get stuck there forever.


What other possible ways are there to remove the pattern?
On my phone, I need to draw 5 wrong patterns, before the phone asks for the pin code. But I noticed, that pattern consisting of few points (I think less than 4 points) do not count. 

I hope this observation helps you. You need to draw 5 complex patterns (four or more points) in order to be asked for the pin.
