The issue that I had was getting rid of the mf9 software and baseband. Whenever I flashed mdl the mf9 software and baseband would still be there. I gave up but I need to unroot still and get back to all stock with no custom binary too. I think I might try today again.

No, follow the directions to get back to MDL unrooted, stock rom. Do not root it once there. You may have to do a couple of factory resets for the binaries to get reset so that it's all "official" on the Download screen. Once you get to that point - all official - then take the OTA to go to MF9. That will give you stock rom, unrooted, all official MF9.
From there you can root or not, up to you. I did. But my download screen says custom again of course, now that I've rooted my MF9.
Success!!!! Thank you so much for your help!!!!

I think MF9 locks the baseband in odin when you trip the counter. I found the easiest way to downgrade was to odin MDL or MDC and then let it boot up. It will show as baseband of MF9 still. Go back into odin one more time and load the same version as the first time. The second time will change the baseband because the bootloader is using the MDL or MDC version and not the MF9 version so the second time everything will change and when you re-boot you won't see MF9 anymore. At least this works for me. Hope it helps someone else.
