Help me fix my iPhone please! Device: iPhone 17 Pro Max Timeline: • Installed iOS 27 Public Beta 2 at the end of July — worked fine for ~5 weeks • On September 5, phone started randomly rebooting/shutting down when swiping or opening apps • Forced reboot did not resolve it • Updated to Beta 8 — issue persisted • Updated to RC after Apple Event — issue initially persisted; phone eventually stopped shutting down on swipe, but Telegram and App Store stopped launching • Forced reboot after that → stuck on Apple logo → redirected to Recovery/Restore screen (current state) From crash logs collected before the phone became unresponsive (on Beta 8, build 24A5430a): • Kernel panic: userspace watchdog timeout: no successful checkins from backboardd in 181 seconds • backboardd last exited with SIGNAL, code 10 (SIGBUS) • SpringBoard had 2 induced crashes before the panic • ISP-cp coredump was skipped — IOP was not running, coredump_init returned KERN_NODE_DOWN • A second, separate incident: SpringBoard watchdog timeout (bug_type 409) on its own, without full kernel panic
