Note 5 won't unlock! Any help appreciated

A long story short is, I mistakenly said my Canadian note 5 was Rogers and the provided unlock did not work... I then corrected it to the proper carrier, which was MTS. The replied eventually with the same code. Which did not work..... So I tried another, expensive website... Which returned with the same code... Which did not work. I am now into the unlocks... And nothing! I have unlocked 1000 phones using this method and sites.....

Does anyone have any ideas or solutions? Thanks

In a tight spot, Any Assistance Appreciated~

So after having my HTC M8 for over a year I decided it was time to root it and flash a custom ROM because it was becoming extremely slow and unbearably sluggish. I came across quite a few guides and what not detailing steps and decided on using the Hasoon2000 "All in one Kit." Everything was going smoothly initially, I managed to unlock the bootloader, and flash a custom recovery (TWRP), but then that's when the problems started. I had an issue with updating SuperSU and it gave me an error stating that the binary was not installed and the app would not work without it. I attempted to install it via the playstore and that didn't work either. So I decided to re-flash the custom recovery and see if I couldn't reinstall the SuperSu, BUT after restarting the phone again, I got an error that kept saying that the the AT&T Ready2Go app has stopped working and it repeatedly popped up and wouldn't let me do anything at all. I tried to go into the TWRP Recovery and factory reset the phone, but this is where I royally screwed up, I went into the Advanced Wipe options and without thinking, wiped the "System" and "Cache" portion. Now not only do I have no OS, but my phone isn't event fully rooted because SuperSU was never fully working. I honestly have no idea what to do now and pretty much am without a working phone, great first attempt at rooting my phone huh?!

Also I understand getting a microsd card might facilitate fixing this issue, so probably first thing tomorrow I'll be going to get one.

Maybe Bricked? Frustrated. Guideance Appreciated :(

I'm fairly new to this, bear with me. I'll try to include lots of detail. If I'm asking or posting in the wrong area, just let me know. I've been trying to do this without any hand-holding, but it's been pretty frustrating and it's a lot to soak in and I think I probably got something wrong.

My S4 seems to be partially bricked.

I was given a retired S4. The phone is locked to Bell in Canada (It's an SGH-I337M, not a 9500 en.wikipedia.org/wiki/Samsung_Galaxy_S4#Model_variants ). When it was given to me, it had Cyanogenmod 11 on it. The previous owner is techsavy and tried to unlock it, paid for several websites to give him codes, none worked and they refunded. This was when the S4 was new, he hadn't tried since.

I wanted to use it with Rogers. I was happy to just pay for an unlock code, but, it seemed I needed to be on the original firmware. So I learned how to use ODIN and downloaded Bell's original firmware. As suggested here: ( galaxys4root.com/galaxy-s4-stock-firmware/ ) and I picked the Bell one ( stockroms.net/file/GalaxyS4/SGH-I337M/I337MVLUAMDJ_I337MOYAAMDJ_BMC.zip ). It seemed that I needed to downgrade anyway to get most of the carrier unlocks to work. (In Canada, IIRC, there was no region lock, just carrier, but regardless it spent two years on a Bell plan).

When I finished using ODIN, successfully, the phone restarted but now appears to not complete booting or be able to flash a new ROM of any kind, at least by methods I've tried.

On powering up:
1 - "Samsung GALAXY S4" in curvy font.
2 - Blue swirly animation of Samsung.
3 - Do do do do doo dooooooooo, audio.
4 - Blue LED in top left stays lit.
5 - SAMSUNG in white on black screen stays there, pulsing with blue light occasionally.
6 - It stays here forever.

It never finishes booting, and it's a hell of a power draw the phone got hot after an hour.

When I try to boot into recovery, I get the blue text in the upper left, but it just reboots.

When I try to put it into download mode, I get a green warning about custom OS's, I can use volume up to agree or volume down to cancel. Either way, it just reboots.

If I try to power it down without pulling the battery, it just boots up, same loop as above, and stays there, pulsing the logo forever.

I can't get to any diagnostic screen, but maybe I'm trying the wrong ones or the wrong ways.

How badly did I mess up my phone?

I'd like to just use it as a camera even, if I can't get it to unlock so I can use Rogers, but it seems I've messed that up now too.

Any help or advice would be greatly appreciated. If you need more detail, I'm happy to give it. (Sorry for bad links, new user, can't post links).
