Troubleshooting AOMEI MBackupper Standard: Common Issues & FixesAOMEI MBackupper Standard is a popular free iOS backup and transfer tool that helps users back up iPhone and iPad data, manage photos, contacts, messages, and transfer files between iOS devices and computers. While the software is generally reliable, users can encounter a variety of issues — connection problems, failed backups, device not recognized, slow transfer speeds, or error messages. This article walks through common problems, practical fixes, and preventive tips to help you get the most from AOMEI MBackupper Standard.
1. Device Not Detected by AOMEI MBackupper
Symptom: The app doesn’t detect your iPhone or iPad when connected via USB.
Common causes:
- Faulty USB cable or port
- iOS device locked or not trusted
- Outdated iTunes or missing Apple drivers (Windows)
- Conflicts with other software (e.g., other mobile management tools)
Fixes:
- Check the cable and port
- Use an official or high-quality Apple-certified Lightning cable.
- Try another USB port on your computer and avoid using USB hubs.
- Unlock and Trust
- Unlock your iPhone/iPad and, when prompted, tap Trust This Computer.
- Install/update iTunes and Apple Mobile Device Support (Windows)
- On Windows, ensure iTunes is installed from Apple’s website or Microsoft Store. This installs necessary drivers.
- Restart the Apple Mobile Device Service (AMDS): open Services (services.msc) → find Apple Mobile Device Service → Restart.
- Reboot devices
- Restart both the computer and the iOS device.
- Close conflicting applications
- Exit other phone management or synchronization tools that might access the device.
- Update AOMEI MBackupper
- Ensure you’re running the latest version; update via the app or AOMEI website.
2. Backup Fails or Stops Midway
Symptom: Backup process aborts with an error or stalls at a percentage.
Common causes:
- Insufficient storage on computer or device (for local backups)
- Corrupted data or incompatible file formats
- Interrupted USB connection
- Software bugs or permission issues
Fixes:
- Check storage space
- Ensure the destination drive has enough free space. Clean up or choose an external drive if needed.
- Use a stable connection
- Replace the cable, use direct USB ports, and avoid moving the device during transfer.
- Close background apps on iOS
- Force-close unnecessary apps to free memory and reduce interference.
- Selective backup
- Try backing up categories separately (e.g., just photos, then messages) to isolate problematic data.
- Update iOS and AOMEI
- Install the latest iOS and AOMEI MBackupper updates to fix compatibility bugs.
- Check for corrupted items
- Remove or transfer questionable files (large videos, corrupted photos) manually and retry.
- Run as administrator (Windows)
- Right-click AOMEI MBackupper → Run as administrator to ensure proper permissions.
3. Transfer Speed Very Slow
Symptom: File transfers take much longer than expected.
Common causes:
- Slow USB connection (USB 2.0 vs USB 3.0)
- Large number of small files (overhead increases)
- Background syncing (iCloud, antivirus scans)
- Computer performance limits
Fixes:
- Use USB 3.0 ports and cables
- Connect to a USB 3.0 port (usually blue) and use compatible cables.
- Disable background syncs temporarily
- Pause iCloud syncing and disable antivirus or indexing temporarily.
- Transfer large files in batches
- Group large items into fewer transfers; avoid moving thousands of small files at once.
- Close unnecessary programs
- Free CPU/RAM to allow faster transfer.
- Convert HEIC to JPEG (if needed)
- If transfers slow due to HEIC decoding, convert photos beforehand or change iPhone camera settings to capture JPEG.
4. Error Messages (Common Codes & Meanings)
Symptom: Specific error codes appear or messages like “Backup failed,” “Device disconnected.”
Common messages and steps:
- “Device disconnected” — Check cable/port, trust prompt, restart AMDS (Windows).
- “Backup failed with error code [xxx]” — Look up the code in AOMEI support; general steps include updating software, checking storage, and trying selective backups.
- “Permission denied” — Run as administrator or check antivirus/firewall settings.
- “Unsupported device” — Ensure iOS version supported by installed AOMEI version.
If an error persists, capture screenshots and note exact wording for AOMEI support or forums.
5. iTunes Backup Encryption Issues
Symptom: AOMEI can’t access encrypted iTunes backups or prompts for a password.
Explanation: AOMEI may rely on existing iTunes backup settings. If iTunes backup encryption is enabled, AOMEI needs the correct password to read or reuse that backup.
Fixes:
- Remember or reset encryption password
- If you know the password, enter it in iTunes to decrypt. If forgotten, you must reset all settings on the iOS device (Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings) — this does NOT erase data but removes the backup password.
- Disable iTunes encryption for new backups
- In iTunes, uncheck “Encrypt iPhone backup” to create unencrypted backups moving forward.
6. Contacts, Messages, or Photos Not Displaying Correctly
Symptom: Certain data categories show incomplete or missing items in AOMEI.
Causes:
- iCloud sync storing data in cloud only
- Permission restrictions on iOS
- Data corruption or format differences
Fixes:
- Ensure local data availability
- If contacts/messages/photos are stored in iCloud, enable local copies or turn off iCloud sync temporarily to force local storage.
- Grant permissions
- On iOS, check Settings → Privacy to ensure AOMEI has access where applicable; also ensure device is unlocked and trusted.
- Export problem items manually
- Use native apps (Photos, Contacts) to export/import missing items as a workaround.
- Use selective backup to isolate the issue and reattempt.
7. App Crashes or Freezes
Symptom: AOMEI MBackupper becomes unresponsive or exits unexpectedly.
Fixes:
- Reinstall AOMEI
- Uninstall, download the latest installer from AOMEI, and reinstall.
- Check system requirements
- Ensure your OS version meets the app’s minimum requirements.
- Run diagnostic logs
- If available, enable logs and send to AOMEI support for analysis.
- Update drivers and OS
- Ensure Windows/macOS updates and Apple drivers are current.
8. Backup Verification and Data Integrity
Advice:
- After backing up, verify backups by restoring a small subset to a test device or checking backup logs.
- Keep multiple backup copies (external drive + cloud) for redundancy.
- Periodically export important items (contacts as vCard, photos to folders) for easier recovery.
9. When to Contact AOMEI Support
Contact support if:
- You encounter persistent, reproducible errors after trying the above fixes.
- You see unexplained data corruption or missing data.
- You need help with specific error codes or log files.
Before contacting support, gather:
- AOMEI version, OS version, iOS version
- Exact error messages and screenshots
- Steps to reproduce the problem
- Log files if available
10. Preventive Tips
- Keep AOMEI MBackupper, iOS, and iTunes/drivers up to date.
- Use quality USB cables and direct ports.
- Maintain sufficient storage on backup destinations.
- Back up regularly and keep at least two copies (local + external/cloud).
- Disable automatic syncing (iCloud) during large transfers to avoid conflicts.
If you want, I can: summarize troubleshooting steps into a one-page checklist, create step-by-step instructions for a specific error code, or draft an email to AOMEI support including logs and reproduction steps. Which would you prefer?
