For iPhone repair technicians

iPhone stuck in a restart loop? The log knows why.

Upload a panic-full file. You get the likely faulty part, the test to run before ordering it, and the repair pitfalls.

Drop your panic-full files

One or more .ips files from the same iPhone, or click to browse.

Where to find the file.

On the iPhone

  1. 1Open Settings › Privacy & Security.
  2. 2Tap Analytics & Improvements › Analytics Data.
  3. 3Open the most recent file starting with “panic-full”.
  4. 4Tap Share and send it (AirDrop, Mail) to the shop computer.

From a computer

  1. 1Connect the iPhone and open 3uTools (or Xcode › Devices and Simulators).
  2. 2Go to the crash logs (Crash Logs / View Device Logs).
  3. 3Export the “panic-full-…ips” files.
  4. 4Drop them all here: the trend is more reliable with several logs.

A method, not a guess.

Frequently asked questions

Is a panic full always a hardware problem?›

No. A single panic can come from an iOS bug, an app or a jailbreak. It becomes a strong hardware clue when the same signature repeats across several logs, especially with a regular restart rhythm.

Does a panic full damage the iPhone?›

The file itself is harmless: it is only a report. The repeated restarts it documents can, however, interrupt updates or data transfers, so back up the device as soon as you can.

Can I delete the panic full files?›

iOS manages these files itself. Deleting them does not fix anything: if the cause is still there, a new panic-full file will be written at the next panic.

Why does the same code mean different parts on different iPhones?›

The sensor array value is a bitmask whose layout changes between generations. 0x200000 is the proximity sensor on an iPhone 14 and the wireless coil on an iPhone 15. Always read a code together with the model.

A log diagnosis guides the repair, it doesn't replace it: always confirm with a known-good part before ordering. Main sources: iFixit wikis and forums (CC BY-NC-SA), DFRWS APAC 2025, technician feedback.
