I am having some problem in installing my app on the iphone as I am constantly getting the following error message
The service is invalid
Please check your setup and try again
(0XE8000022)
It was running perfectly well till yesterday but since yesterday I am having this problem.
It can be a couple of things, the first and inmediate thing I'd check is to see if your IPhone is currently Downloading or "Preparing Update..." whilst this is running you generally get the "Device is invalid (0xe8000084)" / Error MT1006.
This i found to be the most common thing. so try this first.
And if that fails: Restart your IPhone, and then if that fails restart your Mac/Xcode and do a clean then Rebuild and deploy..
Hope this helps
I confirm that restarting your device solves the issue. But if your device is jailbroken with a Semi-tethered jailbreak you will loose it after a reboot.
To prevent this, do a ldrestart(soft reboot).
In order to perform it, download a terminal application from Cydia, then type:
su
Input your password when asked, the default password is "alpine".
Then type
ldrestart
Unplugged the device and connected again with Mac solved my issue. Did not need to clean, build or restart XCode. XCode 10.2.1, iOS 12.3.1 version.
First remove the app from iPhone before building the app from xcode. Then Clean All Targets from xcode and then try to build your app again.
Simply restarting the device (as the alert suggests) fixed the problem, at least on iOS 12.
