I'm trying to restore my iPhone SE (2016) via DFU mode, but iTunes freezes when "Preparing iPhone for Recovery" appears.
Hi there a4abaev,
We'd like to help get your iPhone restored to get back to enjoying it.
You mentioned trying to restore it in 'DFU' mode, but did you mean it's currently in recovery mode?
You also mentioned that iTunes becomes unresponsive when it gets to the step showing 'Preparing iPhone for Recovery'. To confirm, does iTunes in fact become unresponsive where you can't click on anything within it, does it seem to not start downloading the new iOS system, etc. The more details you provide, the better equipped we'll be to assist.
Have you already tried any steps on your own? Here are some examples of steps to take for what's happening: restarting your computer, trying to restore from another computer, confirming you have the latest update for iTunes and Microsoft updates for Windows
Please keep us posted on the above details in your next message. Take care until then!
