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.

Hi Jaddie, even going back to 2.0.0 did not work here. Still getting the file is invalid message. A 2nd hand Aruba is on its way to me now, if it works then there will be some Cudy kit going on eBay!

I have two Cudy M1800 with firmware version 2.1.3-20240509-102323. I tried to use the file in M1800+V2.zip. However, it says “Not applicable！Please upload the firmware applicable to the following models.” if I try to update firmware from Advance Settings → Firmware. If I try to update the firmware of a specific model, it says “File is invalid. Please retry.”. I have tried downgrading the firmware version of the M1800 devices to 1.16.14-20231117-190903. It gives the same error. What should I do?

That seems to be working, Jon if you follow the 2nd link they gave, there is a 2nd place to update the firmware which works, the normal one errored for me too, but doing it where the 2nd guide shows it is now rolling back to v2.0.0 at which point openwrt should install
Following the openwrt saga. I have several M3000 v1 units and cannot load ANY openwrt file, even with original FW back to 2.0.0. This is very frustrating and I am openly thinking about replacing the whole system (4x M3000, 1x AP3000 Out)… I need separate wireless networks and being limited to 2.4 and 5 is useless… I need a separate 2.4 network for IOT as well as a separate 5 network for IOT, a merged 2.4/5 for everything else and then a guest network…
