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.

@Dear Bourn,
OK. I will upload it to the Google Drive.
“Hello Cudy Support,
Thank you very much for your help. I have received the intermediate firmware, then successfully flashed AP1300 Outdoor v1 OpenWrt firmware on my AP1300 v1.0 device. Everything works correctly, and there is no need to build a custom firmware anymore.
Please consider uploading the intermediate firmware you provided to a public location (for example, Google Drive or your download center). This would help many users configure and migrate their devices more easily.
Thank you again for your support."
Hello Cudy Support,
