Baseband and IMEI not showing up and no mobile service

I have decided to try a rom cause being on stock was getting boring and I couldn't even use Samsung pay so I installed Twrp and then proceeded to restore one of my backups, that's where it stopped working. I had G920TUVU3DOI1 on my phone and I can't manage finding the files to flash. Whenever I try to flash a firmware (5.1.1. It fails, can anyone provide me a link to that version as that is my problem. Currently the phone is working but the IMEI and Baseband numbers are unknown.

Problem with the service mode

Hi,

I would like to manually select LTE frequencies on my note 4.
However, while I can display the service mode, I cannot access to any menu. My phone only shortly displays "0". My Note 4 is a non-rooted N-910F with the COI3 (Android 5.1.1) rom.

How could I manage to access the menus in the service mode?

Thank you for your help!

How do I get texting to work on a Verizon Samsung Galaxy S4 with T-Mobile service?

I just got this phone about a month ago and I am not able to send any text messages but yet, I can receive them. MMS, data, and calling works pretty good too. MMS didn't work at first until I had to change my APN settings. Is there a way to fix this?

Does this problem have something to do with the software version? It's 5.0.1 (lollipop)
