Ipad Air 2 Update Ios 14 Error. Reset Network Settings on iPhone or iPad. Next reboot your computer.
The iOS update requires quite a few free storage space. Now try to updaterestore your device again. Resetting network settings is proven to be a particle practice to get software update smoothly.
Check Your USB Cable.
I note that Finder indicated it needed to perform an update on the device first whereas Configurator 2 did not. Tap on the Close button to exit this error message and wait for a few minutes and then tap on Download and Install again. You can go to Settings General Reset press the Reset Network Settings. Apple Configurator 2 on MacOS Catalina bricked its first iPadOS 14 update for me yesterday even when the iPad was in Recovery Mode.
