Android Pattern Lock Extraction Using JTAG

Another way you can try
enter the recovery mood
connect to pc
if usb debug works in this mood
select mount data
and delete /data/system/*.key in cmd.
if usb debug does not word in this mood
change to a higher edtion of recovery
these is risky you cannt open the phone
but you also can backup phone data in recovery mood

Hi,

As I know,the key point of Android pattern lock is /DATA/SYSTEM/GESTURE.KEY . If the usb debug is on,you could use adb cmd to backup data from android phone. Then try to decrypt GESTURE.KEY. there is a tool called LockPatternUtils.java you could find it on the internet..
Of course you could use dictionary attack to decrypt GESTURE.KEY..the combination is not as big as you imagine…so it won't take long..

Well the major trouble here is that the USB Debugging is not enabled. But obviously i will go with your advice if i am able to get the dump.Thanks a lot

Hi

I think Ufed Chinex can solve it. It's made to acquire smart phones made in China with chipset like MTK…

Sorry I made a mistake. Above answer is for the other question…

Just out of curiosity, why do you need the screen lock code if you already have a JTAG physical image?

Hi
I just wanted to know it. No particular reason.
