[Q] Need help With Bell Galaxy S4, going back to 4.2.2

Need a little help here as I am not sure if this will work. I have the Bell Mobiliy variant of the Galaxy S4 and my phone is currently on baseband: i337MVLUGOC4 and the build number is : LRX22C.I33OCUGOC3
I currently have the latest version of TWRP installed. I recently did an OTA update which was giving me considerable amounts of trouble so I decided to flash a rom from here.
I found the following;
I flashed a stock I337_OC3 rom from this thread:
http://forum.xda-developers.com/galaxy-s4-att/development/rom-100-stock-i337oc3-5-0-mdl-t3098197
I'd like to go backwards and flash a Canadian stock S4 firmware using Odin, titled the following:
Bell Galaxy S4 SGH-I337M VLUAMDJ (Android 4.2.2)
Can anyone tell me if this is safe to do?
Thanks for all your help

Galaxy s4 I9505 Upadte (Baseband)

Hello
I do have a Galaxy S4 LTE I9505 on H3G, now my phone is on the CM 5.1.1 lollipop and I want to turn it back to the official rom, I find two ROM's one to the baseband I9505XXUHOD7 and the other to I9505XXUGNJ3 which is my current one.
Now i want install the official ROM with the baseband I9505XXUHOD7 because its on the 5.0.1 and the other original is on the 4.4.2. So my question is if I can install the ROM with the baseband I9505XXUHOD7.

Yes, but you will have to reflash the lollipop firmware one second time if the flashing method don't update the bootloader.

Rom question

Hello. I have a galaxy s5 LTE, g901f on android 5.0.2 and i want to downgrade to 4.4. Can i use a rom from the g900f or is a diffrent one for my version?

It's strongly not recommended to use other version's firmware...brick...

NO! You will brick your phone. It has to be for the g901f. Simply look around the forums. Search for your specific model and you'll find the rom you're looking for. Here is a link for a KitKat firmware called SimpleGX Rom for your phone: http://forum.xda-developers.com/galaxy-s5/development/rom-simplegx-rom-v1-0-0-t2971815

Is it possible to downgrade modem firmware?

According to a forum post somewhere, the Verizon Note 3 when upgraded to Android 5.0 has a loss of signal quality over Android 4.4. I have never used this device with 4.4 but I have noticed that my wife's S4 Mini will have LTE when my note 3 will have 3g and sometimes less than that. I've read somewhere that downgrading the modem to the 4.4 modem firmware can help, but I have not been able to find the 4.4 firmware. Anybody have any input on this whether or not it could work and where I can find the firmware and how to flash it if I find it?
Phone: Verizon Note 3
ROM: Official Lineage OS 7.1.2
Baseband: OF1
Recovery: TWRP
Bootloader: Unlocked/Developer
