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.

@Hi Mikko，
Our technical support has sent you the firmware via email. Please check.
“Hey, could you send the Cudy signed openwrt firmware to WR3000 EU1.0? The file provided in the google drive gives error “File is invalid. Please retry.””
@Dear Ben Dover,
The router M3000 can not downgrade the firmware when installed Mesh system. Please power off other satellite Mesh routers. Then reset the M3000 to factory default. Then you can downgrade the firmware before installing mesh system.
“Hi,
I want to flash OpenWRT on an M3000 with a Motorcomm YT8821 (Variant 2). I downloaded your signed firmware from your Drive, but the file hash doesn’t match the one shown in the web application. Could you confirm if you have an up to date version available?
Thanks”
Hello.
I have a Cudy M3000 V2 EU2.0, board R37.
Hardware from system log:
NAND: GigaDevice F50L1G41LB
WAN PHY: Realtek RTL8221B
Stock firmware: 2.5.28
I downloaded the official intermediary package M3000 1.0_2.0.zip.
The included file:
cudy_m3000-v1-sysupgrade_20251119.bin
causes a boot loop after flashing. Ethernet continuously connects and disconnects.
I can restore the router successfully to stock firmware via TFTP, and it works normally again.
Could you please provide the correct OpenWrt intermediary firmware for my exact hardware revision?
Thank you.
I believe a very similar case has already occurred with the same or very similar hardware parameters — M3000 V2, board R37, F50L1G41LB NAND and RTL8221B PHY — where Cudy support provided a different intermediary firmware directly to the user.
If possible, please send me the same compatible intermediary firmware for this hardware revision instead of the public cudy_m3000-v1-sysupgrade_20251119.bin.
Hi,
Could you provide the OpenWrt firmware for the M3000 using the Motorcomm YT8821 (Variant 2)?
Thank you and have a nice day :)
Hi,
I would like to request for the openwrt firmware (to support vlans) for M3000 with a Motorcomm YT8821 (Variant 2) please.
Thank you
