As I understand your instrucitons:

buckup mtd spi
cat /proc/mtd
cat /dev/mtd(number) > /tmp/(name).bin
cat /dev/mtd0 > /tmp/mtd0.bin

I have done the following on my NBG6616 running OpenWrt 21.02.0-rc2, r16122-c2139eef27

root@n5:/tmp# cat /proc/mtd

dev:    size   erasesize  name
mtd0: 00030000 00010000 "u-boot"
mtd1: 00010000 00010000 "u-boot-env"
mtd2: 00010000 00010000 "art"
mtd3: 00060000 00010000 "zyxel_rfsd"
mtd4: 00060000 00010000 "romd"
mtd5: 00010000 00010000 "header"
mtd6: 00ee0000 00010000 "firmware"
mtd7: 00200000 00010000 "kernel"
mtd8: 00ce0000 00010000 "rootfs"
mtd9: 00970000 00010000 "rootfs_data"

I have created the dumps with
for i in 0 1 2 3 4 5 6 7 8 ; do cat /dev/mtd$i > /tmp/mtd$i.bin; done

How can I transfer the files to you?
