If the powerline utility can't recognize your PA210, I am afraid that you can't save your PA210.

By the way, you can check if there is any reset button on your PA210.
If there is a reset button, you can give a try to reset your PA210 by pressing this reset button to see if there is any luck.

Thanks vincent, but there is no reset button for the TL-PA210.

I have recovered the device compiling these tools: https://github.com/qca/open-plc-utils

downloading this firmware: TPL-307E-NVM-v4.5.0-0-1-X-FINAL

and entering this command line from the linux console:

[CODE]sudo int6kboot -i eth0 -N TPL-307E-NVM-v4.5.0-0-1-X-FINAL.nvm -P TPL-307E-PIB-v45001.pib -FF[/CODE]

Miquel can you help me do this in more detail? I have same problem and want to recover PA210
