Xperia E (C1505) partitions screwed up

Ok, so I may have messed up my Xperia E.
I rooted it with Kingo Root, then decided I wanted to make a FULL backup (nandroid)
google -> Ok, I'm going to need a recover.
unlocked the bootloader through Sony's website -> Bootloop.
tried to flash fresh firmware with flashtool -> still bootloop.
tried different version of firmware -> still bootloop.
used Sony's Xperia Flash tool (emma) -> installed FirefoxOS. WTF?!?
flashtool starts refusing to flash.
able to reflash kernel and system through flashtool's fastboot. -> Stuck on Sony logo.
can't get flashtool to flash firmware.
used fastboot cmdline tool to flash CWM to boot. -> able to get into recovery.
/cache and /sdcard won't mount and won't format. (make_extf4fs failed. Found out through adb shell that it can't be found.)
(/boot /system /data and /external_sd will)

I can get to recovery, fastboot and flashmode, so I'm sure this can be fixed. I just can't figure out how.
(Sadly I'm going to be away from my computer for most of the rest of the day. I've tried to squeeze as much as I can into this post.)
