Troubleshooting StikDebug

Encountering issues with StikDebug? This guide covers the most common pairing, JIT, LocalDevVPN, sideloading, and iOS 26 update problems seen in the current release line.

Connection & Pairing Issues

StikDebug will not connect to my device

  • Check your pairing file: Open iLoader and confirm the pairing file was placed for StikDebug correctly.
  • Use USB for first-time fixes: USB is the most reliable recovery path if wireless behavior seems inconsistent.
  • Restart the workflow: Close StikDebug, reconnect LocalDevVPN if needed, and reopen the app.
  • Verify iOS version expectations: iOS 17.4-18.x is the most stable range. iOS 26 is supported, but app compatibility still varies.

Pairing file expired or invalid

Pairing files can stop working after device resets, restores, or iOS updates. If you updated to iOS 26.4 or a related 3.1 pairing change, create a fresh pairing file before trying anything else.

Device not showing in iLoader

  • Connect via USB and ensure the device is unlocked and trusted.
  • On Windows, confirm iTunes or the required Apple mobile drivers are installed.
  • On Linux, verify usbmuxd is running.
  • Try a different USB cable or port if the device keeps disappearing.

JIT Not Working

JIT enabled but the app still runs slowly

  • Enable JIT before launching the target app.
  • Fully quit the target app and relaunch it after JIT is enabled.
  • Check that the app is one of the known supported apps or a similar sideloaded app with the right entitlements.
  • On iOS 26, remember that some apps may still lag if the app itself has not been updated for newer system behavior.

JIT option is unavailable

Make sure StikDebug is actually connected and that your pairing file is still valid. If the app just updated to a newer iOS 26 build, recreate the pairing file first.

App crashes when JIT is enabled

Update both StikDebug and the target app if newer builds are available. Recent 3.1 releases improved iOS 26 and TXM JIT reliability, but individual apps can still crash if they are outdated or not fully compatible.

LocalDevVPN & Loopback Issues

LocalDevVPN is connected but JIT still fails

  • Disconnect and reconnect LocalDevVPN, then relaunch StikDebug.
  • Make sure the target app is not already running when you enable JIT.
  • If you recently changed network conditions or updated iOS, refresh the pairing file and try again.

Heartbeat or loopback errors

These often point to a stale pairing file, a VPN issue, or a target app that does not behave well on the current iOS version. Refresh the pairing file first, then retry the workflow from a clean app launch.

Installation & Launch Issues

StikDebug crashes on launch

  • Ensure you are on iOS 17.4 or later.
  • Trust the sideloaded developer certificate in Settings -> General -> VPN & Device Management.
  • Reinstall or refresh the app if the signing certificate expired.

Cannot install StikDebug

Use AltStore, SideStore, Sideloadly, or iLoader with a valid Apple ID workflow. If installation fails in one tool, confirm your Apple ID session, anisette state, and app signing limits before assuming the IPA is broken.

Location Simulation Issues

Fake location does not update in the target app

  • Set the simulated location before launching the target app.
  • Keep StikDebug open while the spoofed location is in use.
  • Restart the target app if it cached your older location.

Route simulation behaves oddly

The newer route simulation logic is more realistic, but it still depends on app behavior, permissions, and current iOS handling. If something feels off, stop the simulation, reopen StikDebug, and start a fresh route.
