1. Téléchargez et décompressez le fichier depuisici.
2. Téléchargez le dernier firmware depuis lesite officielet renommez-le en « recovery.bin ».Remarque : vous devez le placer dans le même fichier que les outils Tftpd.
3. Éteignez votre routeur. Débranchez l'adaptateur secteur ou appuyez sur le bouton d'alimentation.
4. Connectez votre ordinateur au port LAN du routeur avec un câble Ethernet.
5. Configurez manuellement l'adresse IP de votre ordinateur sur « 192.168.1.88 ».
6. Exécutez 'tftp32.exe'.
7. Exécutez 'netsh advfirewall désactive l'état de tous les profils' dans la ligne de commande pour désactiver le pare-feu Windows, sinon TFTP sera bloqué. Vous pouvez également désactiver le pare-feu dans le Panneau de configuration de votre ordinateur, comme illustré ci-dessous.
8. Appuyez sur la touche 'Réinitialiser' et maintenez-le enfoncé. Avant que le routeur ne soit allumé et avant que tftp ne commence à télécharger le firmware, ne relâchez pas le bouton 'Réinitialiser' bouton/trou.
9. Allumez le routeur.
10. Lorsque les voyants clignotent tous rapidement ou lorsque tftp commence à télécharger le firmware, vous pouvez relâcher le bouton «Réinitialiser' bouton/trou.
11. Lorsque le voyant clignote lentement, la mise à niveau est terminée.
12. Veuillez récupérer l'adresse IP de votre ordinateur pour qu'elle soit une IP dynamique.
13. Terminé.

1. Download and unzip the file from here. (File is tftpd64.exe when unzipped – I unzipped it to \tftpd in \Downloads, also tried c:\tftpd\ and e:\tftpd\)
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. (I downloaded the latest 2.4.5 firmware for WR3000H, extracted, and renamed file to recovery.bin, and placed it in the \tftpd – all three times)
3. Power off your Router. Unplug the power adapter or press the POWER button. (Unplugged router each time)
4. Connect your computer the Router’s LAN port with an Ethernet cable. (My PC has 3 NICs, 2 onboard, and 1 via PCIe. Onboard are Gigabit and 2.5 Gb, PCIe is 10 Gb. I disable 2.5 and 10, and connect 1 Gb directly to router, and I have tried the LAN ports and the WAN port.)
(Note: I run VMs, so 1 Gb and 2.5 Gb are bridged with virtual NICs for Hyper-V, could this be the issue?)
5. Configure your computer’s IP address to be ‘192.168.1.88’ manually. (Open Windows 11 settings, —> Network and Internet tab —> Advanced Network settings —> verify 2.5 and 10 Gb NICs are disabled, then for 1 Gb NIC More adapter options —> enable IP v4, then click Properties then enter IP address 192.168.1.88 and Subnet gets filled in 255.255.255.0 and then click OK.)
6. Run ‘tftp32.exe’. (I have to run tftpd64.exe, but yeah)
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. (I tried both ways, each iteration of trial and error I tried command or I tried using Control Panel to disable both firewalls.)
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. (I press and hold the reset button)
9. Power on the Router. (I plug it in and enable power button)
10. When the Lights are all flashing fast, or when tftp start to download the firmware, you can release the ‘Reset’ button/hole. (Only power light flashes. Tftpd never starts downloading anything. If I let go of reset button while it is flashing fast, this stops after a while. If I continue to hold the reset button after a minute or so it stops flashing, goes to a slow blink, but still no download from tftpd)
11. When the light flashes slowly, the upgrade is complete. (never actually downloads file, and there is no upgrade process. Attempting to remove and connect again leaves me with no interface at all, will not generate IP for NIC, and neither is there an SSH daemon running.)
12. Please recover your computer’s IP address to be dynamic IP. (I do this after powering off after step 10)
13. Done. (Not done for me)
So, as I said, verbatim, the steps above.
@Dear John,
So what steps have you done when recover the router. Please tell me one by one in details.
“I have a WR3000H (one of three that I just bought last week using the BOGO Amazon offer) that I flashed correctly to OpenWrt, and after setting it up, disconnected from to move it to it’s final location.
Upon powering it up, nothing works, brought it back to my test bench, and nothing works. The instructions here to restore it to Cudy firmware are also not working – tftpd64 does nothing, never starts downloading the recovery.bin to the device, and during startup when connected to my PC, my NIC briefly gets an IP address of 192.168.1.1, but nothing else ever happens (noticed this phenomenon when I first brought it back to find out why it was not registering on my network).
I’ve followed the steps above explicitly (including unplugging the other NICs in the PC from active connections), but it is not working at all."

@Уважаемый вася,
К сожалению, заводская информация по умолчанию маршрутизатора была удалена. Мы не можем ее восстановить. Рекомендую вам приобрести новый маршрутизатор.
“здравствуйте,на wr300 после возвращения с openwrt на официальную прошивку,поле создания/ввода пароля не активно,а под ним строка “Неверная информация о доске!”из-за чего нельзя войти в настройки устройства и настроить его.Как исправить?”
