How to Flash Chip of a Router With a Programmer | TP-Link Router Repair & MAC address change

In this video tutorial, I show how to flash chip of a router with a programmer. Also, I show how to change MAC address of the router (you can see it at the end of the video).

Why do such flashing:
Such repair procedure can be helpful after wrong or unsuccessful flashing.
I flashed my router because I wanted to go back to an older firmware, but TP-Link blocked it with a firmware lock (error 18005), but with a programmer, I flashed it anyway.

I also show in the video how to change MAC address of the router using a programmer, MAC address stored in the chip so you can easily change it using a programmer.

What programmer did I use:
I programmed my chip with a CH341A programmer

Update: Now, I am happily using OpenWRT with W25Q128FVSIG chip, I upgraded the router's chip from 4MB to 16MB. OpenWRT is much more stable and offers a lot of functionality. And In case I break the firmware I can restore everything with the setting and installed packets in a matter of minutes because the chip is outside, and I have a full dump. Cheers!

I've changed MAC address to 00-11-22-33-44-55 :) you can see it at 09:16, it is the most fun thing that I did using a programmer.

Your tutorial is clear and easy to understand. Awesome

[copetimusmaximus]

Thank you for mentioning the need for a full flash firmware, and the mac address.
Btw, have you tried reading the chip still soldered in the router (using a clip)?

[AhmedHasan-limi]

I did same way, using dump file. Extracted from working router ( extracted using CLIP) of programmer.
But not booting only two light glowing, one full glowing another half glowing.

I did modified the Hex values of mac address of my tp-link tl-wr840n and it's worked...

Hello sir, this is the first video of an YouTube who's explaining everything very easly, can you link me to all tools you used in this video, from the 0 to 100.
I really want to do it EXACTLY how you did, thank you. And keep it up!

It's a beautiful video, thanks for teach.

Hi. Thanks for the information. Can I use clip adapter without unsoldering flash ic. I mean directly on the board with out removing it?

[ElectricalPro]

Hi, guys, why do TP-Link lock their firmware from downgrade? any idea? It seems like only EU firmware has such lock.

[markmado]

thank you so much. I was looking how to change mac address.

[diddierhilarion]

I think it's easier to flash to openwrt and flash from openwrt to the old firmware, desoldering a programming it's useful when you bricked the router, and the backup methods like tftp or serial don't work

[mtalhakhalid]

good job man i had a old router didnt save its settings i guess it need to be flashed as well

[gigaflexinformatica]

Boa noite, precisando da firmware de inicialização do TP-Link wdr4300? Alguém por favor...

[atexnik]

There are readily available clips that attach to the chip directly without soldering. Never heard of them?

[VOTMentalist]

thank you, very useful knowledge ... success is always for you.
Regard

useful tutorial and informative, however it is not easy to find another original full dump. me too was thinking the same way about how to reflash using programmer. (using .bin firmware) :D, full dump backup of installed firmware .bin.

Saludos y gracias por el aporte, más abajo del binario también se le puede cambiar la clave wifi que trae por defecto en: 0001FE00

Great tutorial
I have a cisco wag120n and wifi is not working every time but the internet and dsl light works
Does flashing it well solve the problem
Another question if you mind does the mac address location 0001FC00 is for all of the routers?
