Do this
adb devices
adb shell
cd data
cd system
rm passwork.key (for PIN and password)
rm gesture.key (for pattern)
C:\android-sdk\platform-tools>adb devices
List of devices attached
c16079a4137277f recovery


C:\android-sdk\platform-tools>cd data
The system cannot find the path specified.

C:\android-sdk\platform-tools>adb shell
[email protected]:/ $ cd data
cd data
[email protected]:/data $ cd system
cd system
/system/bin/sh: cd: /data/system - No such file or directory
1|[email protected]:/data $
it's ask for sh i think it's ask for su , for root and devices not rooted [ /system/bin/sh: cd: /data/system - No such file or directory ]

the terminal cmd not see my devices if i open on lock i do that , with my device open recovery mode

Use this app

My app can temporary disable the lockscreen, but the home button not work.
Install via adb and use this command:
adb shell am start -n hu.hexadecimal.locktester/.UnlockActivity​

Installing apps without usb debugging is not possible.

But you have an another chance:
1. Follow the instructions at here: http://forum.xda-developers.com/galaxy-s2/general/how-to-root-install-cwm-recovery-flash-t1814801 (Install CWM Recovery)
2. Download the AROMA Filemanager (http://forum.xda-developers.com/showthread.php?t=1646108) and place it to sd.
3. Reboot to recovery and select AROMA Filemanager's zip, and install.
4. In AROMA go to settings and mount all partitions.
5. Delete /data/system/settings.db
6. Reboot and enjoy :)
If not working go to step 5. and delete /data/system.

I know this is a old thread but I just unlocked my Tab4 10.1 with this method but I didnt have a settings.db file so just renamed the _password.key to _password.key.old and the sparepassword.key with .old as well. I was like hey what do I gotta lose anyway if I mess it up I'll just restore.. I hit exited out of everything rebooted & presto no more password.. I dont know if this would be the same if I set a pin, what the file would be called but maybe I'll set one and see just for the hell of it.. lol :)
Anyway just thought I'd share that you dont have to panic & lose everything by doing a hard reset..
Cheers !

And thank you to [email protected] !!
