Is the international Galaxy S4 (jfltexx) ROMs compatible with the US Cellular Galaxy S4 (jflteusc)? If so how would I go about rooting and installing CM12 or CM13 for example?

A long as it doesn't have a locked bootloader you should be able to root it.
Find out if it does or does not have a locked bootloader. Depending on the result you can or can not use cf auto root to root.

How would I find out if it has a locked bootloader? I do not have any other (Micro)SIMs to test it with. Everytime I attempt to open the Service Menu, It acts as if it is actually going to dial a number and then says the number is invalid. Where I live I always have to use roaming so when I also try a service code it gives me a Verizon Wireless operator. I even tried shortcuts to the service menu and all it says in a toast notification is "Permission Denied". The default service is US Cellular
Verizon and Sprint lock their bootloaders I think.

Helpful. Another reason I hate Samsung. So glad I was forced to get lollipop, I got absolutely no notice back in JULY 2015 that it was updating, so the next day i woke up to no calls or alarms, just an overheating phone.
It's not Samsung's fault. The decision was made by the carriers, not Samsung. Also, Samsung have to give the update to the carriers in order to add the carrier specific apps before pushing it to the users. That means that each carrier pushes the update independent of Samsung.

I have done lots of reading on this and I am still not sure if the solution really exist ...
AT&T Sansung Galaxy S4 i337 MF3 build
1. Having MF3 build, none of the easy unlock solution worked.
2. Can I go back to any previous stock ROM from MF3 such that any of the easy unlock process would work?
3. Will the rooting methods using this be able to sim unlock my device?
4. I assume not, but will updating my MF3 build to any recent ones (MJ6 or MJ9) solve my problem?
Ultimately I want to unlock my device without having to pay $20- $30.
Any help will be appreciated.
Thanks

Lucky you, I just SIM unlocked my friends Galaxy S4 i337 MF3 from AT&T last night so I can tell you your options.
If your phone is off contract (fully paid) you can call AT&T and ask them for an unlock code.
Pay $10-$30 for a factory unlock code for your device from Ebay or whatever.
Root your device, block the AT&T updater from updating you to 4.3, and get the app Region Lock Away from the Play Store.
AT&T denied us the unlock code so we went with the Region Lock Away app from the Play Store and today my friend just activated his AT&T S4 with a T-Mobile prepaid plan. They transferred his number within a couple hours (4 hours or so) and he's been playing with 4G LTE, texting and calling all morning. He hasn't had cell phone internet before because AT&T is so expensive so he is pretty happy.

I did it and it works. My phone is unlocked now. Is it safe to update to 4.3 now ?

Probably not a good idea. The unlock is a software unlock so updating it might remove it and you might lose root capability as well. For now, wait and see if you can still root after the update. If you can, then you can update, root and reinstall the Region Lock Away.
I have always found the best methods for customizing previous phones on XDA. I hope the developers can easily overcome any bs Verizon puts up to stop root, tether, roms!
Keep up the great work
Thus far, all domestic (US) carrier versions of the S5 have locked bootloader, knox, etc. So challenges here may not be related directly to vzw, although historical bias obviously isn't unwarranted.

This appears to not be accurate at the moment, it's looking like the 900t, T-Mobile, had shipped with an unlocked bootloader

Unlocked, or unlockable?
From anandtech:
"With the Galaxy S5, KNOX has finally come full circle, as all US carrier variants are shipping with a locked bootloader. "

unlocked...feel free to check out the chainfires auto root thread, he states "if his program works on the 900t then the bootloader is unlocked"
multiple people have successfully rooted their 900t using chainfires program
http://forum.xda-developers.com/showthread.php?t=2713950
EDIT: honestly at this point the only proof we have is trusting chainfire, and his determination that if you can flash his auto root then you have an unlocked bootloader...for some people thats proof enough and for others it is not (which i completely understand)
I have a verizon samsung galaxy note 3 as many already know after 4.4.4 was released verizon locked the note 3 boot loader so users cannot down grade back to 4.4.2 and the only successful root process that works is on 4.4.2 at this time as far as I've researched so my question is if I were to pay verizon the sim unlocking fee and switch to a carrier that has a known properly working root process, in theory would this work. ? Any feed back would be great. Hoping this will work??!! If any thing I've said is confusing please reply and I'll try my best to reword it.
You're assuming that when you pay the fee that verizon will flash you with an unlocked boot chain. Don't think it's possible. If I'm not mistaken, some of the trust zones are flashed then locked with a physical fuse.
....
So paying the unlocking fee then say you buy a BYOD (bring your own device) kit from t-mobile, straight talk etc, activate the phone with the new carrier (preferably a carrier that currently has a root method that works) then proceed with rooting said device?
Again I'm new to the forum as well as new to the concert of rooting, flashing custom roms etc so please respond in laymens terms
Idk if it could work, I'm just trying to explore any possible solutions to the problem of when android 4.4.4 was released (verizon released theirs with a locked bootloader and if my reseach is correct, there are root processes working for android versions after 4.4.2 on other cell carriers.
So what I'm trying to figure out is if I found a root process that is known to be working on for example (a root process that works on t-mobile, sprint, at&t etc)if I paid to unlock the damn sim and activate the SM-N900V on a cell carrier that so happens to have a working root process, what is the likely hood of it working?
Or
Will it be a complete waste of time, effort, and money to atempt?

You are confusing 2 different types of "unlocking".
Sim unlocking is not the same as unlocking a bootloader.
The locked bootloader will not be unlocked by Verizon.
The locked bootloader will not allow you to flash a custom kernel or system and prevents the easy rooting methods. Unless someone finds a root method, you will not get root on that device.

I currently have a Verizon Samsung Galaxy S5 phone.
I rooted the phone after I got it but a few months ago I had to unroot the photo so I could send it in to Samsung to fix a problem with the screen and while Samsung did fix the screen problem under warranty, they also installed the latest software update which looks down the boot loader and makes rooting very hard (The VZ S5 forum had a way to root the newer software but only if a certain part of the hardware was a certain chipset and mine phone didn't have that).
So now, I'm looking for a new phone that has a microSD Card and the ability to be rooted.
The IR function of the Galaxy S5 would neat too but I don't have to have it.
From what I've read it appears the LG V20 would fit the bill in regards to the microSD Card and an IR Blaster but from looking online and this forum, I can't seem to find out which models of the LG V20 have an unlocked boot loader and/or can be rooted.
Does anyone know which models have an unlock boot loader and/or can be rooted?
Also, they need to be models that are compatible with Verizon as they as the cell service company I use.
as far as i know, only the T-mobile variant and the international variant have unlockable bootloaders. the verizon variant is locked down , i assume some folks are looking for an exploit, but as of now its still a no-go. i have no idea if/when it might happen, but i wouldnt bank on it being soonish.
Hi,
can anyone provide an updated list of V20 variants with unlockable bootloaders and root?
I ask because I really like the phone, but I rely on having Titanium Backup Root to backup and restore my data and settings.
I also want to be sure that whatever I buy can have a life beyond LG's support for running custom ROMs.

Do not use the stock Sprint software Numbers will not come formatted correctly when you receive phone calls.
For instance when you get a call it should show like this.
+1-808-123-1234
But on the Sprint software with a non Sprint Sim Card it will show like this.
+808-123-1234
So anyone who's saved in your contacts it won't show there phone number. And you also can't easily call them back from your call log.
And this also prevents blocked numbers feature from working correctly.
If you flash the unlocked firmware or you flash the carrier firmware of your choice this issues will go away.

Hmm, maybe this is why Google Voice can't send mms for me? I'm DSU'ed on G935P and using a Mint SIM (T-Mobile). When I try to send a mms from Google Voice, it says mms can't be sent to international numbers.

Nah it wouldn't reverse the unlock status, I'm 200% sure it wouldn't change anything. I personally unlock and flash the latest G955U1 and G950U1 firmware AQH3 on 6 S8+ and 1 S8. It's works great on All US carriers, you can also flash each 4 individual Carrier firmware. I have flash all of the firmware each carrier release on my SPRINT S8's with zero problems. Enjoy
Were did you get their stock firmwares? Looking for,sprints and you used a modified Odin to flash?
Hi, I'm trying to get my unlocked sprint s8 plus to be used on Verizon but no luck so far. Is this even possible.. Any advice would be appreciated. Thanks

Did you ever get your phone unlocked ?
I have a Sprint Galaxy S8+. It has been unlocked by Sprint. I am giving it to my daughter and want to change the firmware to MetroPCS firmware for her. I have the latest T-Mobile and MetroPCS variant firmwares. Do I need a special ODIN to perform this? I'm a little confused because I keep seeing discussions about modded ODIN versions for the Galaxy S8 and S8+
