Zero - USB Boot Button gone

My USB Boot Button on the zero is gone… how can i boot?

Are you trying to boot from the eMMC?

If so, you can boot from sd card first, then dd the image to eMMC, and then you can boot from eMMC.

The USB button is used to flash eMMC.

i tried like this. but it fails and ended with a boot loop

dd if=/dev/mmcblk0p1 of=/dev/mmcblk2p1 bs=1M status=progress

also tried with if=Dietpi…img

ok, i did it with dietpi-imager
