Start by reading its device page in the wiki.

Are you talking about the TP-Link TD-W8980? Its device page is missing the procedure for restoring the stock firmware.
Use the device page for the TD-W9980 instead. Its hardware is identical to the TD-W8980.
Note that I have not tried the restore procedure myself.
