WZR-HP-AG300HにTFTPで純正ファームを書き込めない

WZR-HP-AG300Hをdd-wrtのファームで運用していたんですが。
2.4Gの電波が出なくなったので、
試しにdd-wrtのファームをアップデート。
で、再起動ループに…。

とりあえずバラしてシリアル接続。
シリアルポートへの配線接続はポート穴に2.54mm間隔ヘッダーピンを挿すと楽。

純正ファームを書き込んで一旦元に戻そうと画策。
↓を参考に母艦PC側でTFTPサーバーを立てて書き込もうとする。

[Misc]WZR-HP-G300NH のファームウェア書き込み失敗からの復活

が、ことごとくタイムアウトエラー。
母艦側はWin7 64bitでもVMWarer上のDebian7でも同じくタイムアウト。

元々機器側の故障くさいし、このまま処分かな～。
