Root LOOKING for a recent PROVEN root for STRAIGHT TALK Galaxy s3

[TETRIX]

I've scoured the net countless hours off and on for 18 months. I've yet to find a root for my specific phone model, carrier, baseband etc. I am looking for someone who has done a root to the same phone and parameters I have. Also someone would be nice enough to be somewhat specific in their instructions if this is possible.

Not being a prick about this but I'm trying to be very specific, so I'm not looking for suggestions, or "this should work". I need someone who has done this, on the same model, carrier, version, baseband or whatever pertinent specs that match what my phone is now. Further info on my phone can be provided just please ask and I'll be prompt as possible. I have...

Straight Talks Samsung Galaxy S3 SCH-968C / JELLY BEAN 4.1.2 / BASEBAND H2 OR S968CUDUANH2 / HARDWARE VER S968C.01

Thank you in advance for anyone that took the time to read this as well as offer their help.

The SCH-968C is basically the Verizon i535 with a unlocked bootloader. You can download the current SuperSU update zip and copy to SD card.
Download the current TWRP for the i535 and flash to phone with Odin. Uncheck Auto Reboot in Odin and when you get a Pass, unplug phone and remove battery. Replace battery and use button combo to boot into TWRP. Flash SuperSU update zip in recovery and reboot.
