If you have enabled "usb-debugging" in your phone,  then you can try the following method by m.sabra:

ok so not long ago i had a problem with a locked android device with a pattern and i managed to unlock it using adb,so here's how in case you were stuck one day with a locked device.

the device needs to have usb debugging enabled in case usb debugging isn't enabled and you have cwm you can run the same instructions from cwm,root is not required (though it will be so better if the device was rooted)

this was tested on:gingerbread,ice cream sandwich and jelly bean.

both method are through adb.

method 1:

Code:

adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name='lock_pattern_autolock';
update system set value=0 where name='lockscreen.lockedoutpermanently';
.quit

-AND/OR-

method 2:

Code:

adb shell rm /data/system/gesture.key

and that's a video showing how method 2 is done (thanks to melvinchng) : http://www.youtube.com/watch?v=tVJ7T...layer_embedded

you can try both of them,here is how i managed to remove the lock:

1- run the first method.

2-reboot

3-run the second method

4-reboot

NOTES:

-in the first method each line is a seperate command so click enter after typing each line.

-in the second method type all the command and then press enter.

-after running both methods and rebooting you may see the pattern lock,that doesn't necessarily mean it doesn't work,just try any random pattern and it may unlock then remove the pattern from settings.

-this may and may not work,it may work on some devices and don't on others,so all you can do is trying it but i can't assure it will work.

If the data is not important, Press the Power + V- button until the Samsung logo comes up and there'll be an option to format.

tried this also...........it shows a triangle with a ! symbol inside.........it stays till i remove my battery...............

First you have to get unclock code. 
Switch ON your Samsung mobile phone with a NOT ACCEPTED SIM Card.
Don't bother about what's being displayed on your Samsung Galaxy mobile
Compose : #0111*CODE#.There are various site like classicunlocking.com from where you can get unclock code. You can also check at Samsung India site in its support option
