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.

Hello Cudy Support Team ,
Maybe you have some intermediate , temporary firmware ,that I can flash to my WR3000 v1 using tftp64 so it will restore it’s state to defaults ? with memory erasing and rebuilidng the filesystem ? Thaks in advance.
“@Dear Michael,
I see. I suggest you can try to do it by yourself. We don’t have such instructions.
“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 Support
I have already built a working OpenWrt firmware for AP1300 v1.0, based on the OpenWrt firmware for AP1300 Outdoor v1.0 (same SoC and hardware platform).
The firmware itself builds and boots, but I cannot flash it via TFTP or the web interface because the stock firmware requires a signed image.
To proceed without hardware modification (UART/SPI), I need an intermediate firmware that can be installed via the web interface and allows upgrading to a custom OpenWrt image (without signature verification).
Could you please provide such an intermediate firmware for AP1300 v1.0, or advise if there is an official way to bypass the signature check for development purposes?
Thank you.
“@Dear Bourn,
There is no OpenWrt firmware for AP1300 V1.0 currently. The OpenWrt firmware is not developed by Cudy but by the developers. We need the OpenWrt forum official support the router at first, then we can release a middle firmware for you, then you can use and upgrade to the OpenWrt firmware. "
