1.從 這裡。
2.從 官方網站並將其重新命名為"recovery.bin"。
3.關閉路由器電源。拔掉電源供應器或按電源按鈕。
4.使用乙太網路線將電腦連接到路由器的 LAN 連接埠。
5.手動將電腦的 IP 位址配置為"192.168.1.88"。 6.執行"tftp32.exe"。
7.在命令列中執行"netsh advfirewall set allprofiles state off"來停用Windows防火牆，否則tftp將被阻止。
8.按下"重設"按鈕/孔並按住。在路由器開機和 tftp 開始下載韌體之前，請勿放開"重設"按鈕/孔。 9.開啟路由器電源。 10。當指示燈全部快速閃爍時，或 tftp 開始下載韌體時，您可以放開"重設"按鈕/孔。
11.當燈慢閃時，升級完成。
12.請將您電腦的IP位址還原為動態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."
