iPhone stuck in boot loop, DFU mode / recovery mode not working

Hi community,

my test iPhone running the IOS 17 beta crashed after removing an item from Homekit. It is now stuck in a boot loop - showing the home screen for a split second before then a turning wheel for about 5 seconds and again the home screen for a split second.

Entering DFU mode and recovery mode is possible, but the device doesn't pop up on either of my two Macs (tested on macOS 16 and 17) - the device also doesn't pop up under 'system report's USB page or via Apple Configurator.

Of course I tried three different cables as well.

What can I do? Is this iPhone bricked? Have a Genius appointment for Tuesday - but if we can solve before together, even better.

Mac OS 13 and 14 of course, sorry!

suggest you go to Genius appointment or genius bar
