iPhone 11 stuck in update and dfu mode

Hi everybody

Recently i attached my iPhone to my macbook and received the message to update my ios.

After unpacking etc itunes started updating but failed at +-10%. With failed i mean it got stuck, and after several hours i had to reboot and the device boote into dfu mode.

I had the feeling the connection between the iphone and macbook was interrupted.

Now i cant use my iphone anymore.

Tried to:

- use a windows pc, itunes and different cable.

- tries every way possible to update:

The iphone always gets stuck at +-10% OR +-90%

not sure what i can do anymore...im running out of options 🫤.

Please advice.
