Hello @doudootiana, you can boot into oowow and use the shell terminal to run some commands.

From here you can plug in a usb disk with the uboot bin file, and it should appear in /tmp/mounts/

Your command to write the uboot onto the eMMC should be something like

dd if=VIM1S.u-boot.sd.bin of=/dev/mmcblk0 conv=fsync,notrunc bs=512 skip=1 seek=1
