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.
- How to restore the router to Cudy official firmware? Please read the readme in the file downloaded.

Hello Cudy,
I am trying to install openwrt on an indoor AP3000 V1.1 device. The intermediate images in the google drive you provided don’t work. I’ve also tried placing a recovery.bin and setting a TFTP server with OpenWRT’s firmware but it would not work. Does this device support OpenWRT and how can I obtain a properly signed intermediate image? I’ve currently autoupdated the router with the latest official Cudy firmware.
@Dear Dave,
I think yes, some other customer has developed the OpenWrt firmware for LT400 3.0.
“Hello!
Is there any chance to use OpenWRT on Cudy LT400 v. 3?"
Hello!

“Hello Cudy Support Team,
I recently purchased a Cudy TR3000-256MB router and would like to install the official OpenWrt firmware.
My device information:
- Model: Cudy TR3000-256MB
- Hardware version: TR3000-256MB V1.0
- Regional version: EAEU1.0
- Serial number: S0001302262308301
- Production batch: 2623 (2026)
- Current stock firmware: 2.4.21-20251009-115734
I noticed that the intermediate firmware available on your official website is dated May 2025. However, I have read reports that older intermediate firmware versions may be incompatible with NAND flash chips used in newer production batches, potentially causing the router to become unbootable.
Could you please send me the latest compatible OpenWrt Intermediate Firmware for my specific device, or confirm which firmware file is safe to use?
I would also appreciate clarification on the following questions:
1. Does the intermediate firmware support the NAND flash chip used in my production batch (2623)?
2. Can I safely install it directly through the web interface of my current stock firmware (2.4.21)?
3. After installing the intermediate firmware, can I safely upgrade to the official OpenWrt 25.12.6 release?
4. Could you also provide a compatible recovery firmware in case the installation fails?
I would greatly appreciate it if you could provide the appropriate firmware file or a direct download link.
Thank you for your assistance!
Best regards"
