How to Fix Error 12 in iGlide LocationChanger

iGlide uses the Apple Mobile Device USB Driver installed by iTunes to detect your iPhone. Without this driver, your iPhone will not appear — even if it shows up in Windows Explorer.

1. 1Uninstall old iTunes versions if needed (Settings → Apps → iTunes → Uninstall)
2. 2Download iTunes from apple.com/itunes
3. 3Run the installer and complete the setup
4. 4Follow the official iTunes installation flow from Apple’s website for consistent driver setup
5. 5Restart your computer after installation
6. 6Reconnect your iPhone and try iGlide again

Developer Mode is required on iOS 16 and later. Without it, iGlide cannot communicate with your iPhone even if the USB drivers are installed correctly.

1. 1Connect your iPhone to the computer first (this makes the Developer Mode option appear)
2. 2On iPhone: Settings → Privacy & Security
3. 3Scroll to the bottom and tap Developer Mode
4. 4Toggle Developer Mode ON
5. 5Tap Restart when prompted
6. 6After iPhone restarts, a dialog appears: 'Turn On Developer Mode?' — tap Turn On
7. 7Enter your passcode if prompted
8. 8Reconnect iPhone to computer and open iGlide

When you connect your iPhone, a dialog appears: 'Trust This Computer?'. You must tap Trust and enter your device passcode. If you tapped Don't Trust, iGlide cannot detect your device.

1. 1On iPhone: Settings → General → Transfer or Reset iPhone
2. 2Tap Reset → Reset Location & Privacy
3. 3Enter your passcode
4. 4Disconnect and reconnect your iPhone
5. 5Tap Trust when the dialog appears
6. 6Enter your device passcode

Not all USB cables support data transfer. Many third-party cables are charge-only and cannot carry the data signal iGlide needs.

1. 1Use the original Apple Lightning or USB-C cable that came with your iPhone
2. 2Try connecting to a different USB port on your computer (directly on the motherboard, not a hub)
3. 3Avoid USB extension cables or docks
4. 4If possible, test with another original Apple cable

Not all iOS versions are supported. Apple changed internal APIs in iOS 17.0–17.4 that iGlide depends on, making those versions incompatible.

1. 1Check your iOS version: Settings → General → About → iOS Version
2. 2If iOS 17.0–17.4: Settings → General → Software Update → Download and Install (upgrade to 17.5+)
3. 3If iOS 16.x: Fully supported — continue to next check
4. 4If iOS 17.5+: Fully supported — continue to next check
5. 5If iOS 15.x or earlier: Supported — no Developer Mode needed

A corrupted connection state, cached driver error, or stale USB enumeration can prevent detection. Restarting both devices clears this state.

1. 1Disconnect your iPhone from the computer
2. 2Restart your iPhone: hold Side + Volume Down → slide to power off → wait 30 seconds → power on
3. 3Restart your computer
4. 4After both devices have fully restarted, reconnect the iPhone
5. 5Tap Trust if the prompt appears
6. 6Open iGlide and try connecting again

If the driver is corrupted or partially installed, a fresh reinstall is required. This involves removing all Apple software and driver residue before reinstalling.

1. 1Open Settings → Apps
2. 2Uninstall in this order: iTunes → Apple Mobile Device Support → Apple Application Support (32-bit) → Apple Application Support (64-bit) → Bonjour → iCloud (if installed)
3. 3Open Windows Explorer → navigate to C:\Program Files\Common Files\Apple
4. 4Delete the entire Apple folder if it exists
5. 5Navigate to C:\Program Files (x86)\Common Files\Apple and delete if it exists
6. 6Restart your computer
7. 7Download and install iTunes fresh from Apple’s official website
8. 8Reconnect your iPhone

If you are using the PoGo IPA or MHN IPA installed via Sideloadly, incomplete installation or an untrusted certificate can also cause Error 12 or device issues.

1. 1Make sure the IPA was successfully installed via Sideloadly (log should show 'Done' or 'InstallComplete')
2. 2On iPhone: Settings → General → VPN & Device Management
3. 3Find your Apple ID under 'Developer App' and tap it → tap Trust → confirm
4. 4If the IPA shows 'Untrusted Developer' when opening — trust the certificate above
5. 5If the IPA expired (7-day limit), re-sign it via Sideloadly
6. 6Disconnect and reconnect iPhone, then try iGlide again
