Unbrick router WiFi TP-Link TL-WDR4310 using CH341A flash programmer


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 Thank you for watching and please subscribe for more useful videos
