Note 5 help I'm not a noob

[thedroidstr]

So I have been a phone freak for several years, ever since the Droid 1 days. I have successfully rooted all my phones. Until recently, I bought a note 5 from a private party. Brought it home and stuck my Sim card in and phone calls work great but no 4g. So I powered the phone off did a factory reset and knoticed it has a rom. (I think cyanogenmod). I want to set the phone back to stock. I thought easy flash the md5 in Odin and done. But no....... Tried Samsung keis, smart switch. (phone won't recognize in either) don't tell me to reinstall drivers, I have tried, and computer recognizes phone just kies and smart switch doesn't. Any ideas would be helpful thanks in advance here is my phone info
Model number sm-9200
Android version 5.1.1 (connection fails when try to update ota)
Let me know what other info I can provide. Again thanks

Bump, seriously no one has an idea?

Everyone is preoccupied with the Note 7 atm. If achieving 4g is your first goal, are your APN settings correct? Presumably you will be on a different carrier than the previous owner.

Can I just flash the sm-n920t over the sm-n9200? That's t-mobile. I have found out this phone is from Korea I thing. Not local that's for sure

Yes phone is not recognized by odin, smartswitch, but is recognized by my computer. There is a mismatch error but I can't find out where
