and execute the following commands in the router's shell
export rootfs=$(cat /proc/mtd | grep rootfs | grep -v _ | cut -d: -f1)
ubidetach -f -p /dev/${rootfs}
ubiformat /dev/${rootfs} -y -f /tmp/factory.ubi
2. U-Boot Method using UBI Image
Place the factory.ubi file on your TFTP server, enter U-Boot CLI and exec these commands
tftpboot <your_tftp_server_ip>:factory.ubi
flash rootfs
reset
3. U-Boot Method using initramfs Image
(1) Place the openwrt-*-initramfs-fit-uImage.itb file on your TFTP server
and rename it to initramfs.bin
(2) Enable serial console, enter to U-Boot CLI and exec these commands
tftpboot <your_tftp_server_ip>:initramfs.bin
bootm
