Disclaimer: T-Mobile always removes this and did again with the new Nougat update. I'm not sure if any other carriers may have removed this too, but I've placed this in the general Note 5 thread just in case. Unfortunately, I've received quite a bit of short minded ridicule on this subject from people from other service providers who can't possibly imagine that another variant of the Note 5 might actually be different than theirs. So, if you're version of Note 5 has the mobile data toggle standard in quick settings then there is really no reason for you to comment on this thread with negative remarks or unhelpful things like, "I have it on mine". Hope this doesn't sound too harsh, but I ran into some real jerks on this one and really don't care to hear from any more. After all, I'm just on here to help. Any positive feedback you might have though is quite welcome.

Hey guys! For some reason the last couple of roms I've had with T_Mobile didn't have a toggle for mobile data in the quick settings menu. Just in case others are having this issue as well I've decided to add a short tutorial on how to add that toggle and others manually, since the old method of doing this is no longer valid. In older versions of Android you had to use "SQLite Editor" to modify the Settings app in order to add this toggle, but it no longer works like that in more recent versions of Android. This method will require root, but there is also a link to a non-root method at the bottom of this post for those who need it. Anyhow...
Here is a quick explanation of how to fix this issue on the Note 5.
Root Method:
1) Open up a root browser like "ES File Explorer".
2) Navigate to the "/system/csc/" folder and tap on "others.xml" to open it with "ES Note Editor".
3) Search for "CSCFeature_SystemUI_ConfigDefQuickSettingItem".
(The wording of this may be slightly different on your device.)
4) Add the term "MobileData" to the end of the list of quick settings items that are inside the brackets(). Make sure to separate it from the other items with a comma(,).
(You can of course add other Quick Settings items in this same way too.)
5) Then just reboot the device for the changes to take effect.
