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。

Dear Cudy Support Team,
I am writing to request assistance with my Cudy M1800 (AX1800 Whole Home Wi-Fi System) router.
After an unsuccessful firmware update, the router has encountered a critical error. The web interface displays the error message “Invalid board info!” (Неверная информация о доске) and the login/password fields are completely locked out.
Upon further inspection, it appears that the factory/ART partition has been corrupted, and the router’s MAC address has been wiped and reset to 00:00:00:00:00:00. Because of this, the official firmware (currently showing version 2.1.3 in the footer) blocks access. A standard hardware reset via the Reset button does not resolve the issue.
Here are my device details:
• Model: M1800
• Hardware Version: V2.0 (EU2.0)
• S/N: M1800243110049
• Original MAC Address: 80:AF:CA:5C:7C:50
I have attached a photo of the label on the bottom of my router for your verification.
Could you please provide a special service dump, a personalized recovery firmware file, or the appropriate tools/instructions to restore the correct MAC address and board ID to my device via TFTP?
Thank you in advance for your help. I look forward to your reply.
@Hi 呱宝，
感谢分享。
“经测试TR3600在某些openwrt固件下无法刷回官方固件（https://github.com/Crostia/openwrt-Cudy-TR3600-v1），刷去其它的openwrt固件后再按照流程正常刷回官方固件了。看来是个别固件的锅。已解决”

TR3600（BE3600）恢复原厂固件失败。TFTP上传完成后没有刷入动作。红灯继续闪烁，等一会手动重启还是现在的openwrt固件
@Dear Archi,
Our technical support has sent you the firmware via email. Please check.
“TR3000 256MB V1.0 — bricked after flashing intermediate firmware
Hello Cudy Support,
I have a Cudy TR3000 256MB Flash V1.0 router.
Serial number: s0001825262604247
What happened:
I updated the router to the official firmware m_upgrade_TR3000_256MB_Flash-R103-2.5.21-20260708.
After that, I downloaded the intermediate firmware DTS_and_intermediate_firmware_b766f42b-5e1c-4ad5-85b2-53990a85a956 from the TR3000-256MB 1.0 download page.
I flashed this intermediate firmware through the web interface.
After the flash, the router does not boot. It is bricked.
What I need:
The correct TFTP recovery file (recovery.bin) for my specific device.
Step-by-step TFTP recovery instructions for TR3000 256MB V1.0.
Confirmation of which flash chip is installed in my unit (F50L1G41LB or F50L1G41LC).
The correct intermediate firmware for my device revision to install OpenWrt, if my unit has the new flash chip.
Please help me recover the router.
Thank you."
