Update: December 24,2025 Good news!
The OpenWrt forum has merged the pacth which supports the new Flash F50L1G41LC and update the OpenWrt firmware to the version 24.10.5. So if you download the OpenWrt firmware version 24.10.5 or newer version in the future to update the Cudy related models. There will be no problem.
Important Notice: November 24, 2025
Cudy AX3000 series routers manufactured starting in November 2025 (TR3000, SN code start with 2543 or later. 2543 in the SN means the 43th week in the year 2025 ) use the new Flash F50L1G41LC. Upgrading to older versions of OpenWrt intermediate firmware or OpenWrt firmware will prevent the device from booting. Therefore, we will be releasing new firmware updates for these products to add restrictions. If the device is detected to be using the new Flash, it will not be able to upgrade to older firmware versions 2.3.X or earlier. Additionally, previously provided OpenWrt intermediate firmware for older Flash devices will not be compatible.
Affected models include: AP3000 Outdoor 1.0, AP3000 Wall 1.0, M3000 1.0/2.0, TR3000 1.0, WR3000E 1.0, WR3000H 1.0, WR3000S 1.0, and WR3000P 1.0.
Cudy has released the new OpenWrt intermediate firmwares, which have been updated to Google Drive. Please switch to the new intermediate firmware.
Regarding the OpenWrt firmware, we are still waiting for the official OpenWrt forum to release an OpenWrt firmware compatible with the new Flash. Once released, please use the new OpenWrt firmware.
If the SN code is less than 2543. It uses the old flash. There is no such problem.
Warnings
This webpage lists software of devices which support OpenWrt system, before download and install the software, please note that OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Description
- This file can only be used when your router works under Cudy web UI.
- If the router already works under OpenWRT UI, user should restore it to Cudy official firmware first. And then upgrade the router with this firmware.
- How to restore the router to Cudy official firmware? Please read the readme in the file downloaded.

Hi Cudy Support Team , I’ve tried what you suggested – flashing older official firmware, but no luck , my Cudy WR3000 v1 is still bootlooping. Is there any firmware or recovery steps that I might perform in order to recover my router so I be able to boot into GUI ?
One more note : after flashing your firmware from Google drive or OpenWRT firmware, I’m able to enter to OpenWRT failsafe mode and access router via LAN using SSH , but from there I wasn’t able to perform system restoration steps from OpenWRT guides( I just don’t know how to do it propertly) . Thanks is advice for your support.
“@Dear Michael,
You can try to recover the old firmware version. Such as the 2.0.0, 2.2.6. Please connect the LAN port when recovering the firmware.
“Hi Cudy Support Team , I have purchased cudy wr3000 v1 router at the end of y 2023 ,I’ve successpully installed openwrt on my router using intermideate Cudy firmware, that was about 2 years ago. Then year after at 2024 ,I decided to go back to Cudy’s official firmware using OpenWrt system update and latest official firware at that moment .But something went wrong ( as I understood, there was some internal flash incompatibility with newer firmwares and older routers caused by internal flash)
As for today 2026 , my WR3000 v1 router is bootlooping endlessly but I’m able to upload firmware using tftp64.
What I’ve tried:
– Uploading latest official firmware v WR3000-R31-2.4.19 via tftp64 (using WAN port and LAN1 port )
– Uploading itermideate firmware from google drive , using tftp64 via LAN1 port and WAN port ,
– Uploading latest openwrt firmware v24.10.5 using tftp64 via WAN and LAN1 port .
- Uploading openwrt kernel only firmware based on v24.10.5 via WAN and LAN1 port .
Only when uploade official Cudy firmware ,the device rebooted itself autoamtically afer 3-4 minutes. In all cases the device is bootloping after manual or automatic restart.
Do you have any suggestions ? Maybe some firwmare to restore the device ?”"
WR3000P2550 . Can’t change to intermdiate cudy_wr3000p-v1-sysupgrade_20251119.bin: “File is invalid. Please retry.”

Hello,
I own a Cudy AP1300 1.0 access point and would like to install OpenWrt.
https://www.cudy.com/products/ap1300-1-0
Could you please provide an OpenWrt firmware image without signature verification that can be installed via the stock web interface?
@Dear Roman,
Please try to update the intermediate firmware again. Note: The IP address of the router will change to 192.168.1.1 after update. You must check if your computer gets the correct IP address from the router and login the web page with 192.168.1.1.
“Hello! I do have Cudy WR3000E v1.0 with S/N: WR3000E254702030 having problem installing Intermediate firmware to install OpenWrt after that. I’ve tried to install cudy_wr3000e-v1-sysupgrade_20251119.bin from https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj but the router won’t start after installing it. Only 1 LED of Power is working so i have to start the recovery process with Tftpd64.”
