Question about revert back to vendor's firmware

[llkpersonal]

Greetings!

I recently use v1.1.3 installer to flash my E8450, therefore it has only two files in the boot_backup folder. I am wondering in this case how can I go back to the vendor's firmware as there are four files listed in the readme manual.

I assume it should be:

ubidetach -d 0
insmod mtd-rw i_want_a_brick=1
mtd write /tmp/mtd0 /dev/mtd0
mtd write /tmp/mtd1 /dev/mtd1

followed by

mtd -p 0x200000 write /tmp/FW_E8450_1.0.01.101415_prod.img /dev/mtd3

Is it correct?

where do you get /tmp/mtd0 /tmp/mtd1
