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

I think you needs root
But if you install cwm recovery then tool I have posted should work.

It will raise flash counter and you will lose warranty.
Read chainfire's triangle away thread, if your device listed then you can revert warranty.

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​

Sorry for my bad English!

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 !
