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.
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:

Is it necessary that my phone should be rooted for this patch to work?
@mustafabohra:disqus you only need CWM or TWRP recovery not the root..
how to open for my s6 edge please help me
my phone says signature verification failed. what do i do?
@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.
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...
@disqus_cFazCRLLPP:disqus just flash the recovery, use storage mount and transfer file to your device.
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
@robertblocks:disqus Here you go: https://techbeasts.com/2013/12/23/install-latest-twrp-recovery-2-6-3-1-on-samsung-galaxy-s3-i9300-all-variants/
You will need Odin on a PC to flash the recovery using .tar.md5 file.
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.
@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.

Hello, I am trying to unlock a Samsung S4, I keep getting Footer is wrong and signature verification failed messages. Can you help?
@disqus_WXilSFqXTM:disqus what recovery are you using? Try disabling signature verification and then flash this file.
how do I disable the signature verification, I am not seeing that option
@disqus_WXilSFqXTM:disqus what recovery and what device are you using?
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.
@disqus_WXilSFqXTM:disqus Kindly tell me your device's model number.
It is GT-I9500
Hello, any updates on unlocking the Samsung S4
@disqus_WXilSFqXTM:disqus what lock is there on your device?
