Default [Q] Sprint Variant help!

I am just got s-off on my m8. After the exploit ran, I decided to reboot into the bootloader to confirm. Satisfied with the results, I booted back up. As soon as I was back up Blinkfeed kept FCing, making the phone unusable. I rebooted to the recovery to dirty flash the rom, but now the rom fails to flash. What can I do? i cant seem to do anything, and when i boot up the phone is unusable. Any help appriciated.
