Cache gone! Fastboot help topic

So I accidentally deleted my cache partition of my Kindle HD 6 in fastboot. What a dork!

Code:

---

C:\kindle>fastboot update
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt

C:\kindle>fastboot erase cache
erasing 'cache'...
OKAY [  0.086s]

C:\kindle>fastboot format cache
formatting 'cache' partition...
Formatting is not supported for filesystem with type 'unknown'.

C:\kindle>fastboot reboot

C:\kindle>fastboot reboot

^Was the command I entered, and then I rebooted... Now my Kindle is just a happy paper weight that is forever booting up. Any help? I have a factory flash cable coming but I'm unsure how to recreate the cache partition. And I did attempt to, it just said it can't format an unknown filesystem.

Thank you for the help and God bless!
