Trying to flash gs7 edge

I have a sprint galaxy s7 edge that I flashed to att firmware to use on there network. and can't flash back to Sprint to send it in for repair. I keep getting sha256 as a error on Odin every time I try to flash any help would be greatly appreciated
*I'm kinda having trouble understanding EXACTLY what the issue here is, but I think I have the right idea. This is just the way I see it, so please, correct me if I'm wrong.

Your device is a Sprint-branded Galaxy S7 edge and you tried to flash AT&T firmware to it? NOT A GOOD IDEA!

Before you perm-brick your phone, do not, I repeat, DO NOT flash firmware to your device that is designed for a different model number. That's exactly how you kill your phone permanently. If you're gonna flash anything at all to this device, flash the Sprint firmware, not the AT&T firmware (Do some googling on your phones model number and you should find your firmware, if you're lucky). In order to get passed the SHA-256 error, download the Modified ODIN from the link below, which is made to bypass the SHA-256 detection. Remember to be extremely careful when flashing firmware to your device. The smallest screw-up can leave you with an $800 brick. Trust me, I learned that the hard way :(

Odin 3.12 Patched (requires Win-RAR or 7Zip to extract): https://mega.nz/#!jlIlRYLA!AE0yW7A9gi3236cjRFr7QUJslMj6Pjy-pll6OONfgLk

Cheers!
