My Apple Vision Pro is still on visionOS 27.0 beta 4 (24M5326g) and can't update or use any Apple service. Safari works. Software Update offers visionOS 27.2 (24N6120) but stays at "Update Requested". The OTAUpdate log shows: MobileSoftwareUpdateErrorDomain 806 "Failed to download update brain asset, MADownLoadResult:MADownloadDaemonNotReady". App Store can't connect, Apple TV and Games say a network connection is required, iCloud doesn't work, and Media & Purchases hangs at "Signing in to Apple Media Services". Other devices on the same network work normally. Reset All Settings didn't help. devicectl device sysdiagnose fails with CoreDeviceCLISupport.DiagnoseError 0. I don't have a Developer Strap. Has anyone recovered a Vision Pro stuck on an early beta like this without one? Filed as FB25386556.
