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。

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。

@Dear MD RAKIBUL ISLAM,
Yes, you can do it. This method also can recover the broken firmware issue.

@Dear Alan,
Please check if your use the correct firmware. You must use the firmware for TR3000 256MB, which the firmware version on Cudy official website is 2.3.9. Then you can follow the steps as the instruction.
“I am confident that it is the 256MB version because I purchased it from China, and the box, router, label, etc., all indicate “256MB.” However, when I opened the router, I discovered that the chip memory is ESMT F50L1G41LB only 128MB. You can check my post here: [https://www.right.com.cn/forum/thread-8441740-1-1.html] for a screenshot. I also sent this information to sales@cudy.com but haven’t received a reply.”

@Dear Franciska,
1. Please try to power off the router and power on again.
2. Try to change a computer to update the router and check again.
