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。

@Chris,
Thank you for you help. I have sent the method “connect to the WAN port” to Ivan.
“Hi Team, I can answer myself; got it running to flash back to Cudy FW for a TR1200 by connecting to the WAN (!) Port on Cudy; not the LAN port. That was the only thing different for TR1200 compared to the the description above”Hi Team, I can answer myself; got it running to flash back to Cudy FW for a TR1200 by connecting to the WAN (!)

Hi Cudy support, I do have the same issue as Ivan for TR1200.
I could download the TFTP32 for windows and follow all the steps above; but does not work to update / downgrade to original Cudy FW. Can you help?
@Stev0,
Our technical support has sent you the solutions via email. Please check.
“I recently bought a 3-pack M1800 Mesh set. I wanted try OpenWRT and flashed the firmware on all 3 M1800 units. It worked fine. I followed your instructions to return to Cudy’s firmware, i.e. to go from OpenWRT Firmware back to Cudy’s Official Firmware.”
I recently bought a 3-pack M1800 Mesh set. I wanted try OpenWRT and flashed the firmware on all 3 M1800 units. It worked fine. I followed your instructions to return to Cudy’s firmware, i.e. to go from OpenWRT Firmware back to Cudy’s Official Firmware.
However, after successfully flashing Cudy’s newest official firmware for the M1800 v2 (M1800V2-R28-2.1.3-20240509-102323), I get an “invalid board info!” error at the device login page (192.168.10.1) where one needs to create a new admin password. The website-header also reads a strange “lede” title.
I also tried an older firmware version available on Cudy’s website (M1800V2-R28-1.16.14-20231117-190903), but unfortunately receive the same error. After trying to flash a second M1800 mesh unit, the unit also stared giving the same error. I even tried to flash OpenWRT back onto one of the units, but now it does not want to accept the OpenWRT firmware.
What does the “Invalid board info!” error mean and how can it be fixed?
