PanicAnalyzer

An iOS app that reads panic-full, .ips and .crash logs and points to the component most likely at fault. Made by iOSVN for iPhone repair technicians.

Download

Latest builds are on the Releases page.

File	Install with
PanicAnalyzer-unsigned.ipa	Your own signing (ESign, Sideloadly, AltStore…)
PanicAnalyzer-TrollStore.tipa	TrollStore
PanicAnalyzer-rootless.deb	Sileo/Zebra, rootless jailbreak
PanicAnalyzer-rootful.deb	Sileo/Zebra, rootful jailbreak
PanicAnalyzer-roothide.deb	Sileo/Zebra, roothide (Bootstrap, Dopamine roothide)

Remove any IPA install with the same bundle ID before installing the TIPA or DEB. On roothide install PanicAnalyzer-roothide.deb as is: converting the rootless package with RootHide Patcher turns the app's sandbox off and the interface (WebKit) cannot start.

The IPA and TIPA change only with a new app version. Fixes in between reach them as interface updates; native fixes for jailbreaks replace only the .deb files, under the same version and build number.

Features

• Severity: each panic is rated Critical (hardware signs: missing SMC sensors, I2C bus hangs, storage errors, SoC overheating), Watch (watchdog timeouts, sleep/wake hangs, a single kernel panic) or Ignore (Jetsam, third-party app crashes).
• Suspected part: missing SMC sensors and I2C device names are mapped to real components, each with a confidence level.
• Repeat detection: panics with the same cause are grouped with their frequency.
• App crashes: crash reports of other apps (bug_type 309 and 109) are listed apart from kernel panics, with the app, time, exception and termination reason. A scan reads kernel panics first, then the newest files, and says when it hit its limit (100 files / 24 MB over pairing).
• Parts tab: reads the display and battery authentication results that iOS itself publishes in the IORegistry, over the pairing connection, and the serial of each camera module (rear main, ultra wide, telephoto, front, TrueDepth). A camera serial that differs from the factory one is shown as "check", not as "replaced": compare with Parts and Service History.
• Own crashes: if PanicAnalyzer itself crashes, the next start offers to send the details to iOSVN.
• Clean reports: exported reports have serials and UDIDs removed.
• Share Sheet import: share logs straight from Analytics Data in Settings.
• Updates without reinstalling: diagnostic rules (assets/) and interface fixes (web/) are downloaded from this repository at launch.
• Vietnamese, English and Chinese interface.

Reading logs automatically (no jailbreak)

iOS 17.4 or later, with LocalDevVPN (device IP 10.7.0.1):

1. Export a pairing file with iLoader, then in the app use Settings › Import pairing file manually, or copy pairingFile.plist into Files › On My iPhone › PanicAnalyzer. On iOS 27 you can pair on the device instead: tap Pair this device, choose PanicAnalyzer in Settings › Privacy & Security › Developer and enter the PIN.
2. Turn on LocalDevVPN and tap Auto-scan system logs.

The app only reads the CrashReporter folder (com.apple.crashreportcopymobile) and, for the Parts tab, IORegistry through diagnostics_relay; it cannot browse the rest of /var. Pairing records stay in the app's protected storage and are excluded from backups. TrollStore and jailbreak builds read the log folders directly and need no pairing.

Diagnostic rules

The rules live in assets/, separate from the code:

File	Contents
panic_rules.json	Panic signatures and severity
i2c_rules.json	I2C addresses per bus and model
sensor_database.json	SMC sensor codes → part names
model_database.json	Model identifiers → marketing names

Sources: Apple's xnu source, public panic logs from Apple forums, and iFixit. Unverified rules are marked in their source field and rated low confidence. Logs the app cannot identify can be sent to @longdzqua on Telegram.

Releases

• Changes to assets/ or web/ do not build a new installer. Rules are fetched as they are; web-update.yml publishes assets/web_update.json (build number and SHA-256 of each file), and the app uses the new interface from its next start.
• Changes to native code (Swift, Rust) build new installers (build-ipa.yml) with a new build number; the app offers the update when the version or the build number is higher.
• The version label (CFBundleShortVersionString in project.yml) only changes for major releases.
• If the page needs a native action older builds lack, raise NATIVE_API in scripts/web_manifest.py and WebUpdater.nativeApi together.

Building

Requires macOS, Xcode 16+, XcodeGen and Rust:

brew install xcodegen
rustup target add aarch64-apple-ios
bash PairingBridge/build-xcframework.sh
xcodegen generate
open PanicAnalyzer.xcodeproj
