1.从这里下载并解压文件。
2.从官方网站下载最新的固件并将其重命名为“recovery.bin”。
3. 关闭路由器。拔下电源适配器或按下电源按钮。
4. 使用以太网电缆将您的计算机连接到路由器的 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、在命令行中运行“ netsh advfirewall set allprofiles state off ”禁用Windows防火墙，否则tftp将被阻止。
8. 按住“重置”按钮/孔。在路由器通电前和 tftp 开始下载固件前，请勿松开“重置”按钮/孔。
9. 打开路由器电源。
10. 当灯全部快速闪烁时，或者当 tftp 开始下载固件时，您可以松开“重置”按钮/孔。

@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?
