I assume you can use a physical keyboard on an iPhone like I can on Android via USB? Presumably you could buy a wired Czech keyboard to access the device?
Twice I have had the touchscreen fail on Android devices and been able to get what I needed off them using a USB mouse.
For the same reason, plugging in an external keyboard is also a no-go since freshly updated iPhones are placed in what's known as a Before First Unlock state, which prevents wired accessories from working until the passcode is entered.
