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.

“TR3000-256MB EAEU1.0 — request for intermediate firmware and recovery file
Hello Cudy Support,
I sent this request to support@cudy.com on September 28 and again on September 29 (full S/N included in the emails), but have not received a reply yet, so I am posting here as well.
- Model: TR3000-256MB, EAEU1.0
- Production week in S/N: 2623
- Current stock firmware: 2.5.27-20260804-190139
I have NOT flashed anything yet. Another TR3000 256MB owner (S/N week 2626) reported on your recovery FAQ page on September 26 that the router stopped booting after flashing the intermediate firmware from the TR3000-256MB download page (DTS_and_intermediate_firmware, May 2025) on top of stock 2.5.21. My stock firmware is even newer and is not listed on the download page, so I want to confirm compatibility before flashing.
Could you please send me by email:
1. The intermediate firmware confirmed to work with my unit and stock 2.5.27.
2. The stock firmware for TFTP recovery (recovery.bin), ideally 2.5.27.
3. Which NAND flash chip is used in TR3000-256MB units from this batch.
4. Which OpenWrt image to install afterwards (cudy_tr3000-256mb-v1-squashfs-sysupgrade.bin from OpenWrt 25.12.x?).
Thank you!"
@Dear mousegg,
cudy_wr3000h-v1-sysupgrade_20251119.bin is the correct file.
“Hello Cudy Support,
I have a Cudy WR3000H V1.0 (EU).
Router information:
Model: WR3000H_EU V1.0
Serial Number: WR3000H254300*** EU 1.0
Stock Firmware: 2.4.5 US
I would like to install the official OpenWrt firmware.
I understand that routers with SN 2543 or later require the new OpenWrt intermediate firmware for the F50L1G41LC flash.
I found the intermediate firmware:
cudy_wr3000h-v1-sysupgrade_20251119.bin
However, I understand that some WR3000H units with the F50L1G41LC flash and Motorcomm YT8821 WAN PHY report “File is invalid” when using this image.
Could you please provide me with the correct Cudy-signed OpenWrt intermediate firmware specifically compatible with my hardware revision?
I would then like to upgrade to an official OpenWrt version 24.10.5 or newer."
