Topic: TP-Link WR1043ND v.3 Back to original firmware

I´m trying to go back to original firmware my TP-Link WR1043ND v.3

My reference is:
wiki.openwrt.org/toh/tp-link/tl-wr1043nd#back_to_original_firmware

As I understand I have to remove a part of the original firmware but I don't how to to this.
Here is the original instrunction:

"Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware:
dd if=orig.bin of=tplink.bin skip=257 bs=512"

Can anyone understand this?

Thank you in advanced.

Well, you download the original firmware from TP-Link and rename it to orig.bin. Then you issue

dd if=orig.bin of=tplink.bin skip=257 bs=512

The resulting file tplink.bin can then be transferred to the router and be flashed.

One relatively easy further security check would be to compare the resulting file size to OpenWrt's factory image, those need to be exactly the same, up to the last byte.

The discussion might have continued from here.
