1. Download and unzip the file from here.
2. Download the latest firmware from the official website and rename it to 'recovery.bin'. Note: You must put it in the same file of Tftpd tools.
3. Power off your Router. Unplug the power adapter or press the POWER button.
4. Connect your computer the Router's LAN port with an Ethernet cable.
5. Configure your computer's IP address to be '192.168.1.88' manually.
6. Run 'tftp32.exe'.
7. Run 'netsh advfirewall set allprofiles state off' in the command line to disable Windows firewall, otherwise tftp will be blocked. Or you can disable the firewall on the Control Panel of your computer. As shown below.
8. Press the 'Reset' button/hole and hold it. Before the Router is powered on and before tftp start to download the firmware, don't release the 'Reset' button/hole.
9. Power on the Router.
10. When the Lights are all flashing fast, or when tftp start to download the firmware, you can release the 'Reset' button/hole.
11. When the light flashes slowly, the upgrade is complete.
12. Please recover your computer's IP address to be dynamic IP.
13. Done.

@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?
