[Satyam Choudhary1]

i am having SONY XPERIA ZR C5502 and while updating on pc to lollipop, due to my phone battery update started and within 2 seconds my device turned off (50% charged) and then it keeps on restarting.. i need to wipe its cache partition but no key combination is working.. my mobile rom is pure stock rom,, no rooting or unlocking done.. My device usb debugging was on when thiis happened.. please suggest a way to wipe cache only.. i dont want to lose personal data.. can flashtool do only wipe cache partition???
