The only thing I can think of -if you don't have 'heavy machinery' like XRY- is to install CWM recovery on that device via fastboot [fastboot flash recovery nameOfRecovery.img > enter; got to have fastboot & device drivers installed] and flash a little patterns break tool via recovery which I will upload once you confirm you have CWMR installed. That's definitely worth a try.
