The "Unable to restore iDevice (-75)" error in 3uTools is a communication or storage-level failure that prevents the software from mounting the device's file system or writing firmware. It often occurs during an iOS update or restore attempt when the device's storage is nearly full or the connection is unstable. Common Causes

APFS Partition Error: The system cannot mount the APFS data volume, often requiring a full erase rather than a simple update.

Full Storage: If the iPhone's storage was full before the restore, it may trigger this error as it fails to create temporary update files.

Power/Connection Issues: Low voltage from a USB port, a faulty cable, or subpar battery health can disrupt the NAND (storage) power supply during the flash process.

NAND/Hardware Failure: Persistent error 75 across different cables and computers may indicate a hardware issue with the logic board or NAND flash memory. Troubleshooting Steps

Use DFU Mode: Instead of standard Recovery Mode, put your device into DFU mode (the screen should remain black) before attempting the flash in 3uTools.

Enable "Fix Battery Health": In 3uTools under the "Smart Flash" tab, select Quick Flash Mode and ensure the "Fix battery health" checkbox is selected before starting.

Direct Connection: Connect the device directly to a rear USB port on your PC's motherboard (avoid front ports or hubs) using an original Apple cable.

Full Restore (Data Loss): If you were trying to "Retain User's Data," switch to Quick Flash Mode to perform a clean install. This is often necessary if the error message mentions "Missing data volume".

Try iTunes: If 3uTools fails, try the official restore method using Apple Devices or iTunes to see if it provides a different error code or completes the process. ERROR: Unable to restore iDevice(-75). - Apple Community
