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.

- 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.

@Dear JC,
You router still uses the old Flash model. You can update the OpenWrt firmware. Don’t worry about it.
2513 in the SN means the thirteen week in the year 2025. At that time, we still uses the old flash.
“Hi,
I’ve just received my WR3000H from Amazon. I intended to switch to OpenWRT but I’m learning that you changed the ROM in this model recently and the flash will no longer work until your proposed patch has been validated and merged.
First, is my model with S/N WR3000H251301647 EU1.0 concerned? How can I check? I won’t open the device.
Second, what should I do now?”
Dear Shai,
I suggest WR3000S, WR3000H or WR3000E. You can choose one of them.
“Hi again
What model would you recommend as a home Wi-Fi router which is both current (still in production) and supports OpenWRT?”

@Dear Raj,
OK. We will follow this.
“Dear Cudy Team,
Thank you for the recent OpenWrt notice regarding the new Flash chip compatibility (SN 2543+). This information confirms the complexity of flashing your routers.
I am writing to urgently request public confirmation that your R&D team is integrating a fix for a severe and proven performance bug in the WR3000S (V1.0) Firmware 2.4.6. My support case, which includes the requested Diagnosis Bin File, has gone unanswered.
The Critical Issue:
Problem: When the 5GHz band is set to 80MHz Channel Width and 802.11ax mode, the download speed drops drastically to ~3.89 Mbps (I have provided all technical proof to support).
Technical Root Cause: This is a confirmed driver-level issue, specifically the RRM (Radio Resource Management) bug: kern.err kernel: [ 3964.022354] 7981@C00L1,RRM_PeerNeighborReqAction() 846: snprintf error!
Since you are already developing a mandatory new firmware update to handle the new hardware restrictions (as per your notice), please confirm that the fix for this critical RRM performance bug will be integrated into that very next official firmware release for the WR3000S.
The router is currently unusable in its high-speed advertised mode due to this persistent bug. Please provide a clear timeline (ETA) for the official patc”
