Bricked S3 i747 and not sure where to go from here



I wanted to update my S3 from whatever version it was on to the newest one available. I essentially wanted to start with a blank phone I went into the TWRP recovery and wiped cache, system, data, etc. I guess that was the entirely wrong way to do it because after that I installed the dirty unicorn rom (DU_d2att_5.1.1_20150723-1444.v9.4-UNOFFICIAL), and it got stuck on the boot screen. Thinking there was something wrong with the install I tried a factory reset and reflashing. It got stuck on "patching system image unconditionally" because there was something wrong with the system partition I think. I let it sit overnight and it stayed on this part.
The next day I read a bunch of things and thought it was just a bad ROM file or something. I went and downloaded the newest stable cyanogenmod (cm-12.1-20151117-SNAPSHOT-YOG7DAO1K6-d2att) to try and make it work. It installed without error and looked like it was going to work, i even wiped dalvik cache to up the chances of success. It also hung on the boot screen. I left it alone for a few hours and it still didn't progress.
After some more research I found a post that I thought would correct my partitions and make it bootable again. It was using adb commands to do something:
adb shell
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3
reboot
I did this from recovery and the first two commands worked. The third shot back an error. I tried modifying it according to other users who have found success and it didn't work for me. I went ahead and hit reboot anyway and now the phone doesn't respond. It doesn't power on, it only has a charging light when plugged in without the battery.
I have tried to fix this as well, I tried a slew of different debrick.img files on a 16gb sd card formatted with Win32 Disk Imager. None of those were able to get me back to download mode. This is where I'm stumped. Is there a debrick.img I'm supposed to use and haven't found yet? Or am I just SOL with this method?
Thanks in advance :)
