If you're retarded like me and attempt to upgrade to 232 with only 15% battery left you will be screwed at some point during this procedure. The battery does not charge in AP Fastboot or Recovery mode. I was able to fix it by holding vol + and - while turning it on and selecting BP only. It should take you to the battery bar and let it charge. You'll then most likely have to FXZ back to 905 and start over.
