Hi friends,
As I was reading some random post about bypassing the Android lock protection using adb (Android Debug Bridge), I thought why not try something that doesn't require you to connect the phone to computer. The way that came into my mind was using the flashable zip.
What is a flashable zip?
Flashable ZIPs are the zip files that can be flashed into phones using the Recovery found in phones, which is automatically installed when you install custom kernel or root the phone. I tried googling the exact meaning, but couldn't find it. Though from my experience, these ZIPs are generally used to apply updates to the phone.
Why flashable ZIP?
Password of your Android phone can be cleared using adb from you computer, but for that you need a computer, and 'USB Debugging' enabled on your phone. But consider a situation, you forgot your password, have no computer (or you have one) but 'USB Debugging' disabled. In this case, this trick will come handy as these ZIPs don't need any special setting enabled on your phone.
How passwords are stored in Android?

Note:
I've successfully tested this on my rooted Xperia Mini w/ unlocked bootloader. Your phone need to have CWM recovery installed on it. I'm not sure if this requires root permission or not as I don't have any un-rooted device. But this certainly worked on my rooted GB.
What you need?
Demo Android Update.zip -> mackief / update.zip--for-Android-Devices-
Any good editor
Little patience
Busybox installed on your phone(installed automatically when you root, most of the time)
