ఐఫోన్ ఎర్రర్ 75 ను ఎలా పరిష్కరించాలి?

iPhones are designed to offer a smooth and reliable user experience, but like any software-driven device, they can occasionally run into unexpected errors. One issue that frustrates many users is iPhone Error 75, which usually appears during an iOS update or restore using iTunes or Finder. The error message often reads: “The iPhone could not be restored. An unknown error occurred (75).”

Encountering this error can be stressful, especially when your iPhone becomes stuck, unresponsive, or unusable during the process. For many users, error 75 appears suddenly, even when everything seemed to be working fine before. Fortunately, this problem is typically software-related, not hardware damage, and can usually be fixed with the right steps.

In this article, we’ll explain why iPhone Error 75 occurs, walk you through effective solutions, and introduce an advanced fix for stubborn iOS system errors that standard methods can’t resolve.

1. Why Does iPhone Error 75 Occur?

Understanding the cause of iPhone Error 75 is the first step toward fixing it. This error usually means that communication between your iPhone, computer, and Apple’s servers was interrupted or failed during the update or restore process. Below are the most common reasons:

1.1 Outdated iTunes or macOS

If you’re using an older version of iTunes (on Windows) or macOS Finder (on Mac), it may not fully support the latest iOS firmware. This compatibility issue often leads to restore or update failures.

1.2 Corrupted or Incomplete iOS Firmware

A damaged or partially downloaded IPSW firmware file can prevent iTunes or Finder from completing the restore process, triggering error 75.

1.3 Security Software Interference

Firewalls, antivirus programs, or VPNs can block iTunes or Finder from accessing Apple’s servers, causing verification to fail.

1.4 USB Connection Problems

Using a faulty cable, USB hub, or unstable port can interrupt data transfer between your iPhone and computer during the update or restore.

1.5 iOS System Glitches

Underlying system bugs, failed updates, or corrupted iOS files can also cause iPhone Error 75, especially after major iOS upgrades.

2. How to Resolve iPhone Error 75

Below are proven solutions, starting with basic fixes and moving to more advanced methods.

2.1 Update iTunes or macOS

Always ensure you’re running the latest software:

This ensures full compatibility with current iOS firmware.

2.2 Check Your USB Cable and Port

Connection issues are a surprisingly common cause of error 75:

• Use the original Apple USB cable
• Plug directly into your computer (avoid USB hubs)
• వేరే USB పోర్ట్‌ని ప్రయత్నించండి
• If possible, try another cable

A stable connection is essential for restoring or updating iOS.

2.3 Temporarily Disable Antivirus, Firewall, or VPN

Security software can block Apple server communication:

• Disable antivirus and firewall software temporarily
• Turn off any active VPN
• Retry the update or restore process
• Re-enable protection once finished

This step alone resolves error 75 for many users.

2.4 Restart Your iPhone and Computer

Simple restarts can clear temporary system conflicts:

• Restart your computer
• Force restart your iPhone: To force restart your iPhone, on iPhone 8 or later, press Volume Up, then Volume Down, and hold the Side button; on iPhone 7/7 Plus, hold the Volume Down and Side buttons together; and on iPhone 6s or earlier, hold the Home and Power buttons at the same time.

Then reconnect your iPhone and try again.

2.5 Use Recovery Mode

If normal restoration fails, Recovery Mode can help:

• Connect your iPhone to the computer
• Force restart until the recovery screen appears
• When prompted, choose Update first
• If Update fails, try Restore

Recovery Mode reinstalls iOS without immediately erasing data (when Update is selected).

2.6 Restore iPhone Using DFU Mode

DFU (Device Firmware Update) mode is a deeper restore method that bypasses the current iOS system:

• It allows iTunes or Finder to reinstall firmware from scratch
• Particularly useful for persistent error 75 issues
• Note: DFU restore erases all data

This method is effective but can be complex and risky for non-technical users.
