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.

Answer 1

If you have to click OK after entering your passcode, this command will unlock your phone:

adb shell input text XXXX && adb shell input keyevent 66

Where

• XXXX is your passcode.
• 66 is keycode of button OK.
• adb shell input text XXXX will enter your passcode.
• adb shell input keyevent 66 will simulate click the OK button

Answer 2

This command helps you to unlock phone using ADB

adb shell input keyevent 82 # unlock

Answer 3

Tested in Nexus 5:

adb shell input keyevent 26 #Pressing the lock button
adb shell input touchscreen swipe 930 880 930 380 #Swipe UP
adb shell input text XXXX #Entering your passcode
adb shell input keyevent 66 #Pressing Enter

Worked for me.
