Nowadays many android phone
users use the inbuilt “pattern locks”
as a security to their phones. But
the main problem with it is that, if
you forget the pattern you used
and you try out many wrong attempts, it gets locked
permanently. So, just follow these
simple steps to unlock pattern locks
on your android device and use it
again free of cost. Steps to be followed : Unlock using Google Account : If you don’t have data connection
or internet access or if you don’t
have your google account linked to
your phone, then, you can skip this
step and refer the Additional TRICK. When you try different patterns and
unable to unlock your phone in five
attempts. Then a message pop-up
and shows two buttons “next” and
“try again”. Now click on “next”
button and you see two options for unlocking phone. One is answer the
security question and the second
option is to provide Google account
details. Mostly people don’t set a security
question. But if you set it then
simply answer the question and
unlock your device quickly.
Otherwise check the Google
account option and click “next”.Now provide your Google account
username and password attached
with your device and click on “sign
in”. After that you are directed to
choose new pattern and now you
can unlock with this pattern. Additional TRICK: NOTE: This method deletes all your
data and apps. The following steps are
intended for both rooted and
non-rooted android devices.
For rooted phones, patterns can
be unlocked even without
factory reset which we will be updating later on after thorough
verifications. 1) Switch off the phone. 2) Now hold these buttons all
together at the same time “Volume up + Home Key + Power
Button” until the phone boots (if you device
doesn’t have a home button just
hold together volume up key and
power key) 3) Now a screen like DOS will come
up with different options 4) Use the volume key to move up
and down then scroll down to
“Restore Factory Defaults” or
“Delete all User Data” depending on
which is on your device. Select this
factory reset option and then press power button to let the action begin. Now it asks you for confirmation,
select “yes”. 5) After clicking on the settings
above, now scroll down to “Reboot
System Now” and wait for your
phone to reboot (restart). Now your phone will reboot and all
lock patterns have been removed
and your device will now in its
default settings.
