socd-iboot — Unknown

Difference from “AP watchdog expired”: there, the main processor froze and the hardware watchdog restarted the device, with no text in the report. Here, the boot firmware itself (iBoot, called mBoot on recent iPhones) panicked; on the next boot, iOS only recovered the SOCD report (diagnostics kept across the restart) and displayed it as a panic. Unlike the watchdog case, the SOCDContainers block of an “iBoot panic” is readable: once decoded (base64), it contains iBoot's message in plain text. On an iPhone 14 Pro Max log (iOS 27.0): “iBoot Panic: ANS2 : Recoverable PANIC assert failed … MSP 0 asserted”; an ANS2 panic points to the NAND storage controller (iFixit). Without this decoding, the “iBoot panic” text does not say which component is at fault.
