Checking the firmware on a locked iPhone can be useful for troubleshooting issues, determining if updates are available, or ensuring that the device is running the latest software. However, since the iPhone is locked, accessing the firmware information may require additional steps or tools.
The firmware on an iPhone contains the low-level software that controls the device’s hardware and functionality. It is important to keep the firmware up to date to ensure optimal performance, security, and compatibility with the latest features and apps. Additionally, checking the firmware can help identify any potential issues or vulnerabilities that may need to be addressed.
