I have an android device- Samsung Grand Quattro, yesterday i forgot the pin to unlock my device, now my android device is locked and i am unable to use it and unfortunately its not showing any link to unlock it through google account.

However i was trying to root it and wanted to install CWM recovery through odin, and when i used odin to install .tar file after showing pass and green indicator, my device rebooted and when i want to enter recovery mode it just shows yellow warning sign and rebooted automatically rather then entering into recovery mode.

Now the thing is that how can i deal with the yellow warning sign as my device is locked and is unable to enter the recovery mode. and how can i unlock my pin protected device without losing any data.

Any suggestions or trick that can work ?
