How can I change a untrusted devloper to a trusted devloper for clash of clans on tweakbox untrusted company or devloper on tweakbox

Tweakbox is system for side-loading apps. Side-loading apps from outside of the App Store is not supported. And it is just a silly thing to do as you have no idea what, exactly, is being installed when you side load apps from internet sites. Along with what you think your getting, you could well be getting all sorts of malware since you have no control of what a tweakbox installer puts on your device.

And much of the software in tweakbox is being illegally distributed to begin with. Clash of clans is owned by its developer, SuperCell and I guarantee you they did not grant anyone rights to distribute their proprietary property via tweakbox. Supercell’s apps are already legally distributed, by them, via Apple’s App Store.

I can think of no reason an intelligent, rational human being would want an app on their phone that is not trusted.

Settings doesn’t have any download capability, so there is something you are not telling us.

Maybe from Settings in the Clash of Clans app itself???

Thanks for that info Michael. I'll keep that info in my toolbox.

Are you trying to download this from the App Store? If not, that is why you cannot download it.
