Introduction to DFU Mode

DFU mode is different from normal restore mode or recovery mode. When an iPhone is in DFU mode, the device is not loaded with the operating system and does not boot up like usual. Instead, it allows you to interact directly with the iPhone’s firmware. This mode is often used when normal restore mode fails to fix software issues or when you want to downgrade to a previous iOS version.

It’s important to note that putting your iPhone in DFU mode should be done with caution as it can potentially lead to data loss or other complications. Make sure to back up your device before proceeding.
