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.

Hello and greetings of the day!!
when would the captive portal feature which got recently added to the WR1300 and WR3000, will be available for the R700. I regularly check blog posts for updates but haven’t found any information.
I’ve been unable to find any existing solutions for captive portal authentication on the R700. I also checked for OpenWRT firmware support but found none, and I’m unsure if it will be available in the future.
I’d like to request that the Cudy development team implement the captive portal feature in an upcoming R700 firmware update.
Thanks in advance.
PS: Blog posts previewing upcoming features would be very helpful, not just those announcing released updates.
@Dear Hermann,
Our technical support has sent you the solutions via email. Please check.
“I just bought a Cudy AP3000 Outdoor v1 (Serial# AP3000OD244001666 EU1.0) and want to put OpenWRT on it. As described, I downloaded the AP3000 firmware from your site and tried to flash it.
→ This results in a bricked router! (fixed red light).
I could debrick the router with the original firmware and TFTP, however, I still want to put OpenWRT on this device.
→ So it seems, the provided package here is not suitable for my system:

Maybe you can send me a correct firmware?
Best Regards,
Hermann"

@Dear Pavel,
It is very difficult for developers to develop the OpenWRT firmware due to the WiFi driver of the broadcom chip. So for now, there is no OpenWRT firmware for our BE3600 and BE6500 WiFi product. We don’t have the OpenWRT firmware too. The OpenWRT firmware is not developped by Cudy but the developers.
