1. 从这里下载并解压文件。
2. 从官方网站下载最新固件，并将其重命名为“recovery.bin”。注意：必须将其放在与 Tftpd 工具相同的文件夹中。
3. 关闭路由器电源。拔下电源适配器或按下电源按钮。
4. 使用以太网线将电脑连接到路由器的 LAN 端口。
注意：只有一款型号例外：TR1200。固件恢复期间必须连接 WAN 端口。其他所有型号均使用 LAN 端口。
5. 手动将计算机的 IP 地址配置为“192.168.1.88”。
6. 运行“ tftp32.exe ”。
7. 在命令行运行“ netsh advfirewall set allprofiles state off ”命令来禁用Windows防火墙，否则TFTP连接将被阻止。或者，您也可以在计算机的控制面板中禁用防火墙，如下所示。
8. 按住“重置”按钮/孔。在路由器通电之前以及TFTP开始下载固件之前，不要松开“重置”按钮/孔。
9. 打开路由器电源。
10. 当所有指示灯快速闪烁，或者 tftp 开始下载固件时，您可以松开“重置”按钮/孔。
11. 当指示灯缓慢闪烁时，升级完成。
12. 请将您电脑的 IP 地址恢复为动态 IP。
13. 完成。

TR3000 256mb sn2550，recovery.bin文件用的2.4.22原版固件，恢复出厂遇到问题：
1. 到TFPT刷写完毕后，指示灯从红白快速闪烁 – 短时间白灯 – 一直持续慢速红白闪烁
2. DHCP失效，不分配路由IP。无法登入192.168.10.1。
@Dear Will,

@Dear Will,
TR1200 is different with other models. You must connect your computer to the WAN port of TR1200 when recovering. Please have a try.
“Hi, I tried all the steps above, but my TR1200 still isn’t being detected by TFTP. I tested on both Windows and Mac (using native TFTP), and also tried PuTTY to check for any serial logs, but didn’t see anything. Can you help please?”
