I did some debugging on this and I noticed that the issue occurs because of the 'WaitForDisconnect' field being sent to the 'com.apple.mobile.diagnostics_relay' service. I haven't debugged the service itself(not that I can actually do it properly) but I tested out and only the 'Request' field is actually needed by the service to successfully reboot the device - 'WaitForDisconnect', 'DisplayPass' and 'DisplayFail' seem to be obsolete. Still there is probably a reason that it was implemented like this and I'll refrain from fixing stuff by just removing stuff and leave this as information that could potentially help @danielpaulus fix it

P.S.: This seems to occur for the first reboot only. I also tested:

• Removing 'WaitForDisconnect' field
• Rebooting the device successfully without it
• Adding 'WaitForDisconnect' back
• Attempting to reboot again - successful

Thanks for the investigation @shamanec. Just want to chime in and confirm the issue. We are aware of circumstances where a reboot fails with go-ios, but succeeds tidevice. (In otherwords, there's a working implementation that can be referenced https://github.com/alibaba/taobao-iphone-device)

Seems to be most prevalent when the phone is severely hosed up (in other words, exactly when you need to be able to remotely reboot).

I've encountered a similar phenomenon. For me, it was not the "first reboot", but many reboots later.

Much like @deepakarorawins, I'm using iOS 15.4.1 as well (iPhone 13 connected to a Windows PC). Recently, I have noticed some issues when using the 'ios reboot' command (which used to work just fine).

Could this be related to the iOS version?

[briankrznarich]

@ssadoun Certainly go-ios's behavior could be tied to IOS device version.

I am not sure I have ever had idevicediagnostics restart fail to restart a device. Maybe give that a try for comparison.
