scp xana@192.168.1.128:Transferências/openwrt-24.10.0-ipq40xx-generic-zte_mf286d-squashfs-sysupgrade.bin /tmp

para colocar o novo firmware:
ubiattach -m 9 #it could return error if ubi was attached before or rootfs part was erased before ubirmvol /dev/ubi0 -N ubi_rootfs #it could return error if rootfs part was erased before ubirmvol /dev/ubi0 -N ubi_rootfs_data #some devices doesn't have it

se der este erro quando executar ubiattach -m 9:

ubi: mtd9 is already attached to ubi0
ubiattach: error!: cannot attach mtd9
error 17 (File exists)

então fazer o seguinte:
ubidetach -m 9 mtd erase /dev/mtd9 ubiattach -m 9 ubirmvol /dev/ubi0 -N ubi_rootfs #provavelmente dá erro ubirmvol /dev/ubi0 -N ubi_rootfs_data #provavelmente dá erro sysupgrade -n openwrt-24.10.0-ipq40xx-generic-zte_mf286d-squashfs-sysupgrade.bin
