0 Flares 0 Flares ×

The worst thing that may ever happen to you on planet Earth is, when you forgot your Android smartphone’s password, it may be a pin, a pattern or any other kind of password that you may have implemented on your phone. This may be a case even when someone has changed your device’s password without bringing it in to your notice and you’re unable to get inside your device. The very first thing you would think to do is, you’ll try to apply any recovery options and most probably you will fail. The 2nd choice you’ve is, access your phone’s recovery and reset factory data, sounds quite ugly isn’t it? You will loose all your data just to get inside your device. There is need of a method that can easily grant you the access of your device without wiping/loosing data stored on your device or any settings on your device. In case you’re unable to find any such method, you’ll definitely want to hit your phone on the floor rather than compromising on your data. Well, you may just wait a little and find the remedy to your problem in the very post we’re going through.

Android Lock

Our friend Dr. Ketan (XDA-Recognized Contributor) has developed a great solution to bypass Patterns, Pins, Passwords on Android devices. The solution is packed inside a zip file that you may flash on your phone in case you’ve lost your device’s password, and it will immediately bypass it. What’s the cool thing here is, you won’t have to worry about any data loss or loosing any settings that you’ve made on your phone. Dr. Ketan’s tools earlier was believed to work on Samsung’s Galaxy Devices only, but after trying it on different devices by myself I concluded that the tools is able to bypass lockscreen on most of the Android devices without any hitch. So far this bypass has been tested on Sony Xperia Z, Xperia Z1, HTC One X, HTC One, One S, Sensation XE, Desire, Desire HD, Wildfire, Wildfire S, Samsung Galaxy S4, S3, Note 2, Note 3, Tab 2 7.7 and few other devices and it successfully unlocked all these devices without making any side-effects.

Let’s learn now how to Bypass the Screen Lock using Lock Screen Security Bypass:

      1. First of all you need to have a working CWM or TWRP recovery installed on your device. You may find one here.
      2. Download Lock Screen Security file.
      3. Copy the downloaded .zip file to your phone’s sd card.
      4. Now boot into recovery on your phone. These methods vary for different devices. For HTC you may press Volume Down + Power Key & then select Recovery mode.
      5. For Sony, turn off your device, now turn it on and as soon as you see the Sony logo, press Volume Up key.
      6. For Samsung, turn off of your device completely, now turn it on by pressing and holding Volume Up + Home Button + Power Key.
      7. In case you’ve some other device, try using ADB method explained in this guide.
      8. Once in recovery mode, select “Install Zip > Choose Zip from SD Card > Lock Screen Security > Yes “. 
      9. Wait for the file to get flashed.
      10. Once flashed, reboot your device.
      11. Turn it on now.
      12. Phewww! The lock has vanished.
      13. That’s All! Enjoy

    • Usama Mujtaba

      @melvinnyambe:disqus go to advanced options in recovery and disable signature verification, after that flash the file and let me know if it works or not. Also, make sure that you’re using the latest version of the custom recovery on your phone.

  • Jackson

    My phone is HTC One X, the problem is how am I going to take out the microSD card? Since it cannot be removed in easy way…

    • Usama Mujtaba

      @disqus_cFazCRLLPP:disqus just flash the recovery, use storage mount and transfer file to your device.

  • Robert Blocks

    Thanks you for a great post. I am so new to this so I have a question. where can I find a guide to install CWM on my S3 without rooting? I don’t have USB debugging enabled and I cannot remember my pin. Can cwm be installed from a SD card?. Can I use an andriod tablet to download and transfer to SD or must a PC be used. Thanks

  • Drape

    Can the lockscreen be bypassed if the phone is not rooted and has no custom recovery installed?
    My phone was stolen and I’m hoping the thief cannot access my data.

  • Shahryar M

    @Usama Mujtaba: Hi Usama. I really need your help. Did a crazy thing and changed my pattern while sleepy, now I don’t remember it :-( The gmail+pass thing doesn’t work either for some reason. Neither do the two security flaw codes of *#*#73… (the demo trick and the service menu trick)

    My phone is a Xperia Z1 Compact. I don’t have CWM. Is it possible to install it in this locked-out state, so as to use the guide above for unlocking?

    Your help will be most appreciated.

    • Usama Mujtaba

      @shahryarm:disqus this guide will work for your device. Go ahead and follow the instructions carefully.

    Hello, I am trying to unlock a Samsung S4, I keep getting Footer is wrong and signature verification failed messages. Can you help?

        • Usama Mujtaba

  • Chris

    I am using a Samsung s4. I am not sure about recovery as the phone is locked via numeric passcode. I tried installing the lock screen security bypass but it says footer is wrong and signature verification failed. I am not quite sure how to get a recovery file on the phone as it’s locked. Although I think I saw what ever stock recovery that comes with the phone there on it.

    • Usama Mujtaba

      @disqus_WXilSFqXTM:disqus Kindly tell me your device’s model number.

      • Chris

    I just found a handy tip to bypass lock screens, patterns, pics etc easily & without installing any other software. As long as you signed in with and connected to your Android device then you can use the Android device manager to set a temp password which will then allow you to unlock your mobile. The original guide said it worked for Kitkat but i’ve just tried it on Marshmallow with no problems atall. Now for the guide! –

    On a computer or other mobile phone, visit:
    Sign in using your Google login details that you also used on your locked phone.
    In the ADM interface, select the device you need to unlock (if it isn’t already selected).
    Select ‘Lock’
    In the appearing window, enter a temporary password. You don’t have to enter a recovery message. Now click ‘Lock’ again.
    If it was successful, you should see a confirmation below the box with the buttons Ring, Lock and Erase.
    On your phone you should now see a password field in which you should enter the temporary password. This should unlock your phone.
    Now, before you go on with your life, go to your phone’s lock screen settings and disable the temporary password.
    That’s it, good luck!
