Thanks to http://direct.xda-developers.com/sho....php?t=2451426, I was able to get the original *.img files and drop them in with fastboot.
You'll need to go to http://downloads.codefi.re/autoprime/LG/LG_G2 and download the partitions that you need. After that is done, run the following (replacing with your file names along the way):
fastboot flash aboot aboot.img fastboot flash boot boot.img fastboot flash tz tz.img fastboot flash rpm rpm.img fastboot flash modem modem.img fastboot flash laf laf.img fastboot flash sbl1 sbl1.img
After that's done, you need to flash the *.img file for the recovery that you want. For instance, mine would be:
fastboot flash recovery twrp.img
