1. Scarica e decomprimi il file da qui.
2. Scarica il firmware più recente da sito ufficiale e rinominarlo in "recovery.bin".
3. Spegni il router. Scollega l'alimentatore o premi il pulsante POWER.
4. Collega il tuo computer alla porta LAN del router con un cavo Ethernet.
5. Configura manualmente l'indirizzo IP del tuo computer su "192.168.1.88".
6. Esegui "tftp32.exe".
7. Esegui "netsh advfirewall set allprofiles state off" nella riga di comando per disabilitare il firewall di Windows, altrimenti tftp verrà bloccato.
8. Premi il pulsante/foro "Reset" e tienilo premuto. Prima di accendere il router e prima che tftp inizi a scaricare il firmware, non rilasciare il pulsante/foro "Reset".
9. Accendere il router.
10. Quando tutte le luci lampeggiano velocemente o quando tftp inizia a scaricare il firmware, puoi rilasciare il pulsante/foro "Reset".
11. Quando la luce lampeggia lentamente, l'aggiornamento è completo.
12. Ripristina l'indirizzo IP del tuo computer in modo che sia un IP dinamico.
13. Fatto.

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，

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."
