Can't update via OTA

[therealabeeb (Adeeb)]

Hey there,

I may have made a post about this, I can’t remember. But, the issue I have right now, with my iPhone 15, on iOS 18.5 (stable), is that I can’t update OTA. I remember that I messed around with OTA Disabler on Nugget a long time ago, and since then, I have had to update via iTunes. Today, I decided I’ve had enough, so I factory reset my phone, and restored an iCloud backup, thinking that would fix the issue. But, for some reason, it still doesn’t work. Why? How can I fix this without losing my data?

It looks like you’ll need to use Nugget to undo the changes you made, since modifications made through Nugget are included in your backup. So if you restore your data, you’re also restoring Nugget’s edits.

And yes, you did post something similar last year.

Disabled OTA with Cowabunga Lite/Nugget, can't turn back on

I think you need to restore the MobileGestalt file to its original state—the one you exported initially before making any changes. Another solution is to restore your iPhone using iTunes without restoring data from a previous backup. For some reason, iTunes backups retain the changes you previously made.

But, will Nugget still work to undo changes??? I am on iOS 18.5, does mobileGestalt work anymore?

I also do recall trying to check the box to undo OTA disabler, as in unchecking that box, and the problem never fixed then.

I think you can reach out to leminlimez (the creator of Nugget) for help.
Alternatively, you can also open an issue on Nugget’s GitHub page.

I don’t use Nugget anymore, so unfortunately I can’t be of much help

wait, is it possible to restore ios 26 ipsw to my phone, then get my data on there? can’t I just do that without OTA then?

Feel free to try. I’m currently on iOS 26 beta 1 and I also can’t check for OTA updates. It seems to be a bug, both of my devices are unable to check for updates at the moment.
