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.

Hello,
I have a Cudy WR3000 V1.0 EU router.
Serial number starts with: 2539
Current stock firmware: 2.4.19-20250828-192837
I would like to install official OpenWrt.
Please send me the latest Cudy-signed OpenWrt intermediate firmware compatible with my WR3000 V1.0 and this hardware revision.
Thank you.
Greetings,
I would like to request for the signed openwrt firmware for M3000 with a Motorcomm YT8821 (Variant 2) please.
Thanks
@Dear Mike,
The firmware file in Google Drive is correct. This is for both hardware version. Please unzip the file before update.
Note: If you have installed Mesh system with the router. You can’t update the firmware. Please power off the other Mesh device. Then reset this router to factory default. You can update this firmware before mesh system installed.
“Hi,
I would also like to request the M3000 V.2 with the Motorcomm YT8821 chip, if that’s possible.
Thank you.”
@Dear Горбунов Михаил,
I think there is some hardware faulty in the router. You can try to contact the seller to request a replacement and try again.
“Hello. I specifically need to install OpenWrt on a Cudy M3000 V2.0. The current issue is not simply with the stock firmware, but with the OpenWrt installation process and the intermediate firmware file.
The situation is as follows:
Router: Cudy M3000 V2.0
I used the intermediate firmware file intended for transitioning from the stock Cudy firmware to OpenWrt.
After flashing that intermediate file, the router does not boot into OpenWrt correctly.
The Ethernet connection periodically goes down and comes back up.
The router appears to enter a reboot/boot loop, with the LED changing states.
There is no stable access to OpenWrt at 192.168.1.1.
Sometimes 192.168.10.1 becomes available again.
So my goal is not just to restore the stock firmware. I need to successfully complete the installation of OpenWrt.
Could you please clarify:
After flashing your intermediate file, should the M3000 V2.0 boot directly into OpenWrt?
If yes, why might my router be entering a boot loop instead of booting OpenWrt?
Is another firmware file required after the intermediate file?
If so, which exact OpenWrt image should be used for Cudy M3000 V2.0?
Should it be a factory.bin, sysupgrade.bin, or a special recovery/install image?
If the next step must be performed via TFTP, please provide the exact procedure:
required filename;
PC IP address;
router IP address;
which LAN port to use;
RESET/power-on sequence;
which firmware image should be transferred.
Could this problem be caused by the intermediate firmware itself or by a specific hardware revision of the M3000 V2.0?
What I need is a working step-by-step procedure for installing OpenWrt on the M3000 V2.0 from its current state, because at the moment the intermediate firmware does not result in a successful OpenWrt boot.
If necessary, I can provide a video of the boot loop, ipconfig/ping output, and the current stock firmware version."
@Dear Su King M’dik,
The firmware file in Google Drive is correct. This is for both hardware version. Our technical support has sent you the firmware via email. Please check.
“hello,
Could you send the OpenWrt firmware for the M3000 using the Motorcomm YT8821 (Variant 2) please?
I love your products, but you need to include a seperated download page for this.”
