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.

Dear Customer,
Thanks for contacting the Cudy support team. What is the hardware version of your M1800? You can try to recover old version firmware of the router and check again.
“Trying to flash Cudy’s firmware from official site in my M1800 after flashing OpenWRT and I am also getting the ‘Invalid board info!’ message at the Luci login page. Can’t do anything? I’m reading through the comments and there are lots of users reporting this. Please deliver a workaround”
