Default [Q]Downgraded after using slapmymoto on Droid Mini and Softbricked

I made the mistake from trying to downgrade from 4.4 to 4.2 after using my slapmymoto because I didn't root my phone properly. I soft bricked my phone (stuck in fastboot after trying to flash). Is there anything I can do? Thanks!

Edit: Not sure if this helps at all, but factory mode boots, recovery and normal do not.
