How to unlock android phone through ADB

Question

My screen is dead and I want to unlock my phone so I can access it through Kies to backup my pictures   I locked the phone through Android Device Manager setting an easy password  was hoping for an Unlock option once I locked it  and tried various methods to unlock it for example   adb shell input text 1234   Since I don t know what the lock screen look like I m not sure of the correct inputs to unlock it   I know the phone is on and that it responds to adb  I am also able to run apps on it through Eclipse  It s a Samsung Galaxy S5 with Android 5 0

If you had MyPhoneExplorer installed and connected (not sure this is a must, happened to be my setup already), you could use it to control the screen with your computer mouse. It connects via ADB, for which your normal USB cable is enough.

Another solution I found that even worked without a reboot is updating tables in settings.db and locksettings.db I had to switch to root to open the settings.db though:

 adb shell
 su
 sqlite3 /data/data/com.android.providers.settings/databases/settings.db

 update secure set value=1 where name='lockscreen.disabled';
 .quit

 sqlite3 /data/system/locksettings.db

 update locksettings set value=0 where name='lock_pattern_autlock';
 update locksettings set value=1 where name='lockscreen.disabled';
 .quit

Source that made me edit my tables

If you have USB-Debugging ADB enabled on your phone and your PC is authorized for debugging on your phone then you can try one of the follwing tools  scrcpy scrcpy connects over adb to your device and executes a temporary app to stream the contents of your screen to your PC and you re able to remote control your device  It works on GNU Linux  Windows and macOS  Vysor Vysor is a chrome web app that connects to your device via adb and installs a companion app to stream your screen content to the PC  You can then remote control your device with your mouse  MonkeyRemote MonkeyRemote is a remote control tool written by myself before I found Vysor  It also connects through adb and lets you control your device by mouse but in contrast to Vysor  the streamed screen content updates very slow   1 frame per second   The upside is that there is no need for a companion app to be installed

I would like to share my way  first of all i had Huawei ascend p7 and my touch screen stopped handling touch  so none of the above solutions helped me to be unlock the phone  i have found a better clever way to do it since i can see the screen on thus i thought that my display is 1080 x 1920 px thus i had to simulate a drawing on my photoshop with keypad with  x y  so i can try instead with  input mouse tap command     Since i have pin lock as you can see in the picture  i have got all the  x y  for all the numbers on the screen to simulate touch and unlock my screen and have to backup my data  thus if my password is 123 i did all the following commands  adb shell input mouse tap 100 1150 adb shell input mouse tap 500 1150 adb shell input mouse tap 900 1150   And then my phone just got unlocked  i hope it was helpful
