Stuck at Erasing

I tried doing a factory reset on my Nexus 6 and the device got stuck in "Erasing". All I am able to do now is enter fastboot flash mode but none of the options work as the boot loader is locked. Tried flashing with a factory image from here but that too failed because the device is locked. -------------------------------------------- Bootloader Version...: moto-apq8084-72.01 Baseband Version.....: D4.01-9625-05.42+FSG-9625-02.113 Serial Number........: ZX1G524DKM -------------------------------------------- checking product...
