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.

@Mariusz and Denys,
The reason for this problem is that the base production information of the router was erased or overwritten when the OpenWrt firmware was upgraded. Sorry to tell you that there is no suitable workaround at this time.
I’m having same issue after recovery from OpenWRT to original Cudy firmware. Having error “Invalid board info!”. Using M1800 router. Thank you!
Hi same story here with my m1800 after flashing back from openwrt it dose login to router setting but doesn’t allow to do anything its saying invalid board etc. Can you please tell me what can I do with that ?

“您好，我的TR3000在刷入過渡韌體後再刷入KWRT後就連不上，疑似是檔案過大。後來用tftp刷回時有出現download且紅白燈交替慢閃，持續約五分鐘後還是一樣，改回DHCP也是無法連接。”
