Disabled ota for ios18.3 beta

my iOS is 18.3 and I had never got the update reminder before today. After researching, i downloaded the OTA and hoped it worked.

Unfortunately, it’s not. May I know how to stopped the reminder? my iPhone is only 128GB, or am I have to update and use the intelligent
Thank you

So, you want to stay on iOS 18.3, right? Could you share a screenshot of the update reminder you’re getting?

Also, if you want to block iOS updates, you can install the Block OTA profile.

hello, thank you for your reply.
yes, I have downloaded Block OTA profile already, but the reminder still here. also, i turn off my auto update of ios

I think you need to update to iOS 18.3.2 to remove this notification.

Previously, jailbroken devices could easily remove this update reminder, but unfortunately, iOS 18 cannot be jailbroken at the moment.
