“Unfortunately, Lightning to USB-C cables cannot be used to enter DFU mode and cause problems. There is nothing that can be done about it, and that includes USB-C cables from Apple and third-party cable manufacturers. If the cable does not work, we recommend you to use a USB-A cable with the help of a USB-A to C adapter, if necessary. “

Technically, they explain this issue as follows:

“BootROM will switch to DFU only if it detects USB voltage. This goes all the way to ensuring that certain pins on the Tristar chip are controlled. Since the Tristar chips do this based on the ID of the cable used, we think that USB-A and USB-C cables have different IDs. One of the USB-C cables causes the Tristar chip to fail to display the USB voltage pin. “

In addition, do not use any USB multiplexer Hub. Use only USB-C to USB-A adapter if necessary.
