Welcome to Free Wifi and Internet marketing. There are several videos in my channel guiding how to debrick/unbrick WiFi router using TFTP or serial console

However with this TP-Link WDR4310 the u-boot is damaged so LED pattern is only 1 LED and nothing happen after power up

In this case, both tftp and serial console debrick methods could not help because there is no program in u-boot

The only way we can do is copy whole flash chip to this router

It is easy to de-solder SOP8 flash chip, just add some tin in both sides of the chip

Then heat up both side

Clean up the board

And clean up the chip as well

Now we will clip the chip and connect it to ch341a chip programmer

We can detect the chip and see if it is working

The chip program is damaged so we cannot read any useful information from it.

Now I have loaded the information from another working chip to the buffer

Then we have to erase the chip, make sure it is empty before we write to it

Click program to start writing to the chip

Wait until it finish writing

Finally, solder the new programed chip back to WiFi router board

LED pattern shows that my router is de-bricked and works again

I do some final test with RJ-45 cable connecting to it LAN and WAN ports
