Model: TD-W8970  
Hardware Version: V3
Firmware Version:

Hello. After a firmware update gone wrong, I need to reinstall the firmware of a TP-Link TD-W8970 v3.0 !!
The router is without firmware, only accessible through Serial connection UART and some cp2102 usb.

Unfortunately the v3 version uses brcm63xx and Broadcom, and the Uboot is CFE bootloader, this updated version is very poor and not user friendly.
I tried to push the firmware, using TFTP server from Windows but I always end up with error CFE -21.

I looked a lot unfortunatly could dont find the correct process to restore this router through serial.
here are some stuffs I used :

Thx

Hi@DrZipZwan,

Thank you for your reply.

 

You can refer to page 3 of TD-W8970(EU)_V3_UG to learn about the LED Explanation.

If you cannot see the SSID of the modem, please hard reset the modem for a try:

With the modem router powered on, use a pin to press and hold the Reset button/hole for at least 5 seconds. The router will then reboot to its factory default settings.

 

For further help, it is recommended to contact local support.

  @Joseph-TP Thank very much.

I did not try to install any custom firmware, and I would not come to the official site to look for help, I know that once you install any thing custom on a product, it is not on the official site to go.
An accident happened during update of official TP firmware from PC to Router, the power went down in my house! Such a luck right ?
So now the router is turning on, with only 1 led ON, and only through serial it is accessible. Router not usable.
As explained I looked around how to restore it, but this model is a little different , so maybe some users, came around Broadcom and CFE bootloader .

Thx
