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.

Hi. I want to test openwrt for LT400E v1 (https://github.com/openwrt/openwrt/pull/20660) could you provide firmware without signature checking?
Hi Support team,
Could you send me the intermedia firware for TR3000 128MB, exiting one is not working, thanks.
@Dear Guglielmo,
No, the OpenWrt firmware for WR1300 3.0 and 4.0 are different. We must wait for some developer to develop the OpenWrt firmware for WR1300 4.0 first. Then we can offer the intermediate firmware for WR1300 4.0.
“Hello, I have baught a bunch of WR1300. Some of them are v3, but some came as v4. On v3 i could download the intermediate firmware and the install OpenWrt. Are you going to release the same for v4? I’d like to install openwrt also on them. Thank you! With OpenWrt this is a great product”
@Dear Tod,
Our technical support has sent you the firmware via email. Please check.
