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.

@Dear George,
Sorry for replying so late due to the Chinese Spring Festival！
Our technical support has sent you the firmware via email. Please check.
“Hello, Cudy Team!
I have a Cudy AP3000 V1.0 access point (regular one, not wall, not outdoor), currently running firmware 2.4.4, and I would like to upgrade it to OpenWRT, but the firmware for “Wall” and “Outdoor” devices from the Google Drive link do not work.
Could you please send the official intermediate firmware to my email?
Thanks a lot!”
@Dear Jeroen,
Sorry to tell you that there is no OpenWrt firmware for WR3000 V2.0 now. Please check other Cudy models.
“Hi Cudy,
I accidently bought V2 of WR3000, expecting V1 to flash OpenWrt. While the router is cheap, I am now stuck with a device that could do a lot more if the official OpenWrt is supported!
What was the reason to stop supporting it? It is such a disappointment. Can’t you help the OpenWrt project to support V2 by telling them how you got your version working (which is clearly based on OpenWrt)?
Surely this will cost you potential customers to move away from Cudy? Myself included unfortunately, I will need to replace a functioning router :(”

@Dear Jaroslaw,

1. You said you are not behind CGNAT. But I insist that you should check if the WAN IPv4 address is a public IPv4 address? You can check it on the “System Status” -“WAN”—-“More Details” page. If the IP address is the same as the Public IP address?
2. If you want to install the OpenWrt firmware. You can update the intermediate firmware first, then update the final OpenWrt firmware. There are many video instruction on Youtube. You can search and have a look.

Dear Cudy Support Team,
A few days ago, I bought your router, connected it to the ONT, configured PPPoE and VLAN, and forwarded ports to be visible on torrent trackers.
To my surprise, the redirection does not work. Websites that check port openness (no matter which port I open) always show closed, fail, connection refused, etc.
Is it just me, or does this software version contain a bug that no one has noticed before?
Can I somehow install the official version of OpenWrt and check if that helps? Can you provide me with a specific link to the software and instructions on how to do it so that I don’t brick the router?
For clarity, I will add information about my environment:
- Debian 13 headless,
- Firewall on the host disabled,
- DMZ, regardless of whether it is enabled or disabled, does not work,
- UPnP changes nothing,
- I am not behind CGNAT."

For now, it is not possible to develop the OpenWrt firmware for M3600 and WR6500/H devices. The Wi-Fi drive of broadcom chip in these devices is not open source.
“Hello Cudy team!
Is OpenWRT support planned for the M3600 and WR6500/H devices? I’m really looking forward to the firmware for them"
