[Q] Cannot reach LTE!!!

Hi all! When I got my phone I was able to use LTE 4G on it, and when I rooted and installed a ROM, I was only able to use H+ (maximum). Which is really slow. I've tried different kernels and roms but no success. Now I have the Original Unrooted Samsung Firmware (Hungary/ BASEBAND: I9505XXUDMHA /ANDROID 4.2.2) Please help me!:'( Thank's

[Q] {Q} Updating modem and baseband? HOW TO??

Gentlemen,
I've had my S4 and it's rooted with baseband i337MVLUEMK6. I don't what modem I'm running (HOW TO CHECK??).
I've run a lot of different roms but currently on GoldenEye and Hyperdrive 17.1.
What's the difference between the modem and baseband? How do you check?
The problem is that it's only connecting to the GSM network on Rogers. Is it a modem issue or a baseband issue?
I've read people upgrading to NC1 from MK6 but what are the implications? Locking so I can no longer root and use TWRP? (installed).
I've read and posted with no replies. If someone could shed some light, I'd apprecaite it. How do I check what modem I'm running?
If I could get this to connect to the LTE side, I'd be happy because everything else seems to work fine. Just data is slow on the 3G side.
I'm downloading the latest NC1 firmware from Sammobile now. If I load it, will be return the phone to stock, thus no more rooting and custom
recovery?
Thanks guys. I really like this community..........

What is shows for "BASEBAND" is the modem you have installed. The i337"M" variant has to flash modems with Odin.
Also you need to check your APN for your device as it might be wrong and not allowing the LTE to work. Or you could be in a lye dead zone and only picking up the 3G signals.
I do not have the "M" variant but there are other threads about modems for the i337m that should point you in the right direction

i9505 i337m canada mobile network connectivity

Hello All,
I have a samsung galaxy s4 i337m in canada using the rogers netowork. Ive been using customs roms shortly after i got this phone. Ive used samsung rom, original, GPE but eventually settled on Cyanogenmod. I use TWRP for the i9505 which allows me to use any rom (since CM12 doesnt have a build for the i337m, and other builds wont flash in a i337m TWRP).
Anyway ive been using CM 12.1 with a i9505 build for some time, and it works great. I had to update my modem to the NI2 build to get it to work, but its been working flawless ever since.
Now to my problem, buddy has an S4, same model, same carrier. He claims he needs a new phone and i beg to differ. I rooted, installed twrp (i9505)and cm12.1 (i9505). works great, however no network connectivity. I remember i need a new modem, try the same one that works with mine....nothing... try a different one.... nothing. calls and SMS, but not data of any speed.
Reverting to kitkat roms results in it working perfectly (multiple modems). both from his original Nandroid and CM 11. All lollipop roms seems to have the same issue, no mobile data. Wifi works fine. No issues with SIM card, switched them between the two phones and confirmed its HIS phone with the issue.
Im a little puzzled, can someone recommend a modem to load? should I try to use TWRP an CM12 for the ATT variant/ different variant? I want to help him but this is making me look amateur (even if its true).
Thanks ahead of time.
