Need Help to Debrick S3 Running Cyanogenmod 12.1 android version 5.1.1

I installed Cyanogenmod 12.1 on my sprint s3 with CWM about a month ago; everything was working fine until last night when my phone died on me and after leaving it on the charger over night I woke to find my phone Hard Bricked. Now I know it's not the battery since I have two (both of which I've fully charged via battery charger) and I can't get into download mode or recovery mode; plus given the fact that there is no battery charger light on when phone is plugged into charger; except when the battery is not in the phone then it's only lit up for around 30 seconds: I am absolutely sure that my phone is Hard Bricked (Still not sure as to why my phone Hard Bricked in the first place though), and given the fact that I've lost my old img back up I made when I installed a new linux OS on my PC a few days ago foolishly not backing up all my phone files. Given all that I can say without a doubt that my phone is screwed without any help from someone else, but sadly out of everyone I know personally not one of them seams to have a Sph-L710 S3.

Now I've searched all day now to find a dumped sph-l710 5.1.1 cyanogenmod 12.1 image to no avail (not sure if the recovery software is a factory but I use CLOCKWORKMOD). Now I know that a SD card debrick loader has a chance to not work but I really would like to at least find out whether or not it will help me in my situation, or if I should just finally decide to upgrade to a new device (the latter option is not exactly appealing to me; oh how I love my S3 with its perfect size), If there is anyone that could possible help me out I would greatly appreciate it. So, that is my issue; I hope that you can help if not thanks for the effort of reading this post anyways.
