Unhappy [Q] Soft Bricked - No storage - Wont flash stock recovery

I was texting on my phone when it crashed. I was running SlimKat official release with franco kernel 25 for two weeks. Phone had been running great! Now it bootloops on the google logo and doesn't recognize the 32gb of memory. Wont mount any of the partitions in recovery. When in recovery (TWRP) and I opt to reboot to bootloader or reboot is says NO OS. Now as well all I can do with fastboot is relock the phone. I wanted to reflash the recovery to stock as Google will exchange the phone. When I try and flash the stock recovery in the terminal command window everything looks like its flashing good however when I boot into recovery it still boots TWRP.
Help please.
