Yesterday my colleague asked me for help...She has two android phones , one is hTC and the other is samsung. One day she changed the pattern lock and later she forgot...she tried all possible combination but in vain..
I check her phones and find them not rooted. Fortunately the usb debug mode is on...I decide to use adb command and dictionary attack to crack it.
1.Put the dictionary db into the phone
2.Install android_puzzle_unlock apk
3.Run unlock app
4. Yes~it really figure out the pattern lock guesture key
5. Try to get into the phone
6.Now it works~
7.Then crack hTC
8.Run crack
9.Yes~pattern lock is disabled now
She is very happy and she could use her phone now~
