Ok, this is how I understand it, although I could be wrong on some things....
a) 4g on three has nothing to do with your SIM
b) 4g on Three has nothing to do with your ROM (Stock or Custom)
c) Three have not switched on 4g yet and apparently at first it's only four places, so unless your in one of those there really ain't any rush.
.
d) If your on a stock or even custom rom the 4g network setting does not show as an option, As your rooted though you can use an app called phoneinfo from the play store. Using this app you can change your network setting to anything you want.
e) This one I'm not 100% about, Getting 4g on three can only be modem related, you can upgrade your modem(s) to GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1 without getting Knox.
Please read up about e) as I've spent ages looking for a definitive answer and I think I'm correct, if you find anything else out then get back to me.
.... If anyone else could verify the above that would be great.
Hope this helps a bit ...
Cheers

Three 4G OTA Update on rooted phone
I am in a similar situation, I have a Samsung Galaxy Note 3 SM-N9005 Rooted with Kitkat ROM (Poland) .
I contacted Three UK about the 4G update and asked them to send it to me. I was told that closer to the time I should unroot the phone DL the update and reroot. However I am not sure that would even work for various reasons.
I think that the info mentioned is accurate we just need to establish the correct file for each phone and flash with Odin.
Any further information appreciated.

[Q] How to upgrade to 4.4.2 on N9005 without tripping Knox and keep root?

I am currently on Android 4.3 and everything is stock. I am rooted and also have knox 0x0.
I would like to keep it that way and want to upgrade to KitKat...
What is the best way to do it? I want to have root again, once i am upgraded....
Any advice? I saw many threads on upgrading but all involve flashing through custom recovery and such things, which will trip knox...

update problem after update G900FXXU1ANG8

Hello,
i use a G900F and had root with towelroot.
i did an update on my Phone today to G900FXXU1ANG8. the installation went perfect.
but after the update i tried a new search for a software update and now i got the notification:
the operating system on your device has been modified in an unauthorized way. try downloading software updates using samsung kies on your pc or visit a customer service center.
I also use the app Phone info and when i check my knox counter it says 0X0 so normally this isnt triggerd.
when i connect to kies it just says my Phone has the latest software?

Hi,
u have just lose the Root. towelroot only work with OLD kernel.
i suggest u to Downgrade to ANG2 and use This method to gain Root and stay on this Version Until new trick was discovered to have again root on new stock roms.
Best regards

but i dont want root again. i didnt use it. so what then?

Galaxy S4 USC Unroot?

Hello,
I have a galaxy s4 on 4.4.2 that I rooted using kingroot a while back. It is a US Cellular SCH-R970. Knox has not been tripped. Under device status it says the phone is custom. This means I cannot update to 5.0.1.
My question is, how would I return the phone to official status without 1. Tripping knox, and 2. Keeping all of my data. Also, do you know if I can root with kingroot once I get on 5.0.1.
Baseband is R970TYUFNK1.
Thank You!

Hi,
Flash a proper complete stock firmware via ODIN. Firmware for R970TYUFNK1 is R970TYUFNK1 (itself).

Would you happen to know where I can find a download for that? Also wouldn't flashing that delete everything?
Thanks for all the help!

SamMobile, Samsung Updates, or via SamFirm app. I usually rely on SamFirm.
Edit: As long as Re-partition and NAND Erase All is unticked on Odin, it should be fine.
PS Note: You can install newer firmware over your current firmware via Odin, too.

It would be wise to backup and wipe data before flashing. Otherwise you might encounter problems.
And do not use kingoroot to root lollipop. It used to not work or cause problems. Use cf autoroot method, if your device is supported.

Problem is cf auto root trips knox.
If I flash R970TYUgoh2 would I keep knox at 0x0 and all of my apps? Then I can root with kingroot.

Yes, but backup is mandatory. About Kingroot, see again previous post.

Having knox triggered is just a bunch of crap from Samsung to scare you. Unless you actually use knox. Or if you are afraid from losing your warranty. Which is also crap, because, whilst reading the warranty file, I saw that it won't cover water damage, it won't cover a broken screen and a bunch of other stuff. The only thing it covers is actual hardware failure. And if the phone is new, that's pretty unlikely. Even if it does fail, Samsung has no way to see if knox has been triggered until they change your hardware and are able to boot up the phone. At that point they can't refuse to take it into warranty service anymore.

Wow, that warranty is a load of ****. Also the phone is over a year old so I'd doubt it's still under warranty anyway.
What would you recommend to make a backup? I don't have fast Internet at all (300 kbps down), so I think a local backup would be more efficient.
Thanks for all the help! Have a good Christmas!

OK I flashed 5.0.1 successfully, all my data carried over. Now I need to root. Do you know where I can download the cf autoroot files for jflteusc or sch-r970 on 5.0.1?

There is a cf auto root thread in the general section. Or you could simply google "cf auto root s4".
Make sure to read the thread.

cwm is outdated. Use twrp. And yes, you can install it via odin or other methods.

OK I have that installed now. I'm looking for some new roms and found that there are practically none for the sch-r970. Could I just use roms for the gt i9505 (jflte) or would this not work at all? I'm looking for a 6.0 rom.

JDCTeam AOSP has your device model on the support list. They have Lollipop and Marshmallow.
But you should be able to use other GT-I9505 roms too.

Under their downloads section they have 2 untagged files (doesn't say GSM or cmda) and one GSM (won't work). Will one of the untagged roms work?

Marshmallow roms have been split into gsm and cmda, due to changes in the radio. You have a cmda device.
The initial build of aosp marshmallow was for both cmda and gms devices. The newest build (the december 24th build) is split into two. Gsm version has been released but cmda version needs more work.
So you will have to download the 6th december build which was unified. Or the lollipop builds.
Lollipop builds have a different thread and a different link.

If you root you'll trip Knox and potentially lose your warranty. There's no way around it.
To unroot just flash a stock rom (that you just found) with Odin

This is the same method I used on the W8 model and it worked perfectly. When I decided to unroot, I downloaded the firmware from sammobile and flashed via odin, and that also worked flawlessly.
