Need help to resurrect my NOTE 7 SM-N930X

[topgman80]

I need help. I happen to get my hands on a note 7 sm-n930x live demo unit here in Denver, CO, USA

SM-N930X UD
S/N RF8H71JQGFD
64GB
Exynos 8890 SoC
4x Exynos M1 @ 2.3 GHz
4x Cortex A53 @ 1.6 GHz
Mali T880MP12 GPU

I had it running by flashing a sm-n930f firmware to it, which I understand is the same phone. I then attempted to flash the hydra rom and now I can only access download mode and it stays on the "Hydra Rom N7" splash screen. I dont remember the original phone info because the paper it was written got tossed out. To further my string of bad luck the SD that stored the NAND got corrupted.
I've tried to wipe everything via PIT and reinstall the 930f firmware, but it always fails. Sometimes it fails immediately and other times it actually starts installing for a moment and then fails. I've tried to install Hyrdra again and it fails. I've repartitioned in an attempt to wipe it without success. Info on the 930x version is hard to come by as I've come to find out. Today I finally found the fw listed below is the stock firmware for the international version, but the only downloads I can find are in a foreign language and want me to pay for it which I don't trust at all. At least I think these are the stock for the 930x, please correct me if I'm wrong.
I'm not sure of the baseband because someone threw away the paper I had written it on or the imei # which is all zeros with a one on the end now . How can I fix the loop and get it working again? Is it failing because I can't wipe the cache through recovery and it's too much overwriting at this point? Since this is the "x" international variant, is it accepting of any of the exynos roms? Does anyone have access to the firmware versions below that they could share with me or clue me in as to where I can find the downloads myself?
My goal is to get the Note 7 working again with hydra, or any other rom. I just need it to work and be able to use it on my carrier which is currently at&t. I may have tried to flash the wrong ROM, the efs could be missing, andi know the imei is gone. It is probably safe to assume all are true.
Do I need to repair the imei before it will accept an install? If so, how would you suggest? I have QFIL, QPST, SPC but am unsure exactly how to utilize with great affect as I'm still teaching myself or if they are the correct programs that I need in order to remedy my situation. I'm no pro but I'm not a newbie either. I'm great at following detailed, precise instructions so please guide me to resurrecting my Note 7. I'm not sure what happened but I know I can fix it with a little assistance. All guidance and suggestions are welcomed and greatly appreciated. Cheers

CLARIFICATION: When i stated "I had it working" I meant that i got the demo to stop. Before I could figure out how to make it usable on my carrier I attempted the Hydra install and Bam!, my current dilemma began.

thanks
