Recovery can't mount /system S5 bricked topic

TWRP can't mount /system. Phone is a SM-G900T 16GB
- Running the latest version of TWRP I tried:
- Wiping, repairing, and reformatting from TWRP, also tried formatting data. I get a unable to mount '/system' error message every time.
- Using Odin and Heimdall to reformat using a downloaded .pit, neither works. I ran Heimdall in Windows and Linux (ran as sudo and admin). I re-downloaded the .pit multiple times and tried a couple different sources.
- Installing CWM using Heimdall, and ADB. In ADB and Heimdall I still have TWRP and in Odin it removes the recovery completely.
- Fix permissions gives the unable to mount '/system' error message.
- Installing ROM from Heimdall and TWRM
- Mounting /system with or without MTP

How it happened:
I was running Cyanogenmod 11 with encryption and updated to 12. CM12 was running great, flashed GApps, still running good. I signed in to my Google account and downloaded IPcamera. While running IPcamera I got an email, the screen started going crazy flashing between the alert and IPcamera screen, I couldn't do anything so I pulled the battery. When I rebooted it was stuck in a boot loop. I booted into recovery, it asked for my encryption password as usual. The password didn't work. I tried several times. I rebooted and tried again, still nothing. I rebooted again and this time hit cancel when asked for the password. I wiped everything and got the can't mount /system error. I tried everything above, nothing works.

I can't download my .pit so there is more wrong than just the data partition.

Any ideas? I would love this thing to no longer be a really expensive paperweight. I really can't afford to replace this thing right now :(

Thanks for your help.
