Impossible to Add or Remove iPhone's Ringtone via iTunes

I did. And this is just a part of the whole “can’t add or remove ringtones in iTunes” problem. Removing them via iFunBox is a feasible workaround, but it doesn’t change anything about the fact that iTunes has dropped support for the custom ringtone management entirely. And unless there’s some massive public outcry that would make Apple change their mind, I suppose we’re gonna have to accept that, or look for alternatives that would cover both removing and adding ringtones — like GarageBand.

Goodness… it was really broken on my side in the end. I tested it with my secondary iPhone. Sadly, I had to restore it into the factory settings and set it up as a new phone. After this, it started to work via iTunes again. I'm glad I've found a solution to this, but at the same time, it kind of *****… I've got too much stuff set up on my primary iPhone which I'm not ready to set up all over again just because of this… so I guess I'm gonna have to pass on this, or wait for the iOS 12 to come up and then maybe play with it a little.

As for removing the tones exported by GarageBand, you just select a tone, hit Share and choose the option to export it as a ringtone. You'll get to the screen shown in the below animation — there's an option called "Your Ringtones" — select this to open the list of ringtones, then delete it with the regular swipe-left gesture (or via the Edit button in the corner).

OK, I've just found out that this functionality has simply been removed in iTunes 12.7 entirely. Good job…

We’re going around in circles here. As I said, I don’t have any custom ringtones in either of my iPhones as of now, and yet I can’t add any new ones, not even by dragging m4r files from Finder and dropping them to Tones under the target iPhone in the left menu of iTunes. I’ve even made an internet research to make sure this is no longer an option in iTunes.

The GarageBand’s GUI allows removing ringtones you added before using it, which now makes it the only feasible option for adding it, bypassing iTunes or any other external software entirely.

OK, and now it's started to work on my primary iPhone, as well… all of a sudden, I didn't need to do anything. Maybe you brought some good aura into this, Mr tt2, I have no idea. I'm slowly getting used to Apple toys playing up a bit lately.

Anyway, thank you for your attempts to help me. Hope I've helped you with that GarageBand… otherwise, feel free to ask on.

Take care!

Thanks; I'm fully familiar with this procedure… and as I said, it doesn't work anymore. With either of my iPhones, the result is the same — the tones never appear in the phone transferred like that; using iTunes, they can be neither added nor removed.

As of now, the only option left, apart from buying the overpriced ringtones in the iTunes Store, is using iPhone's GarageBand — import whichever piece of music one fancies and export that as a ringtone.
