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

- 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.

Well, I’m happy to say that I managed to flash OpenWrt on my TR12000. The problem was all my fault. I was using the wrong intermediate image all the time. Once I figured that out everything worked fine. I flashed the intermediate image, then the latest supported image from OpenWrt. Apologies for my mistake and thanks for the help!
Thanks for your response, but the problem is, I never get to flash the intermediate firmware “openwrt-ramips-mt76x8-cudy_m1200-v1-squashfs—flash” contained in M1200 V1 from your Google Drive. I get the “invalid file” error when I try to flash it. I can’t find a way to upload a screenshot so here’s what I get in the Firmware Update dialog when I try to flash the intermediate firmware:
File is invalid. Please retry.

Generally, you need to update the intermediate firmware first. You can download it on the Cudy Google Drive. Then, you can update the OpenWrt firmware of the router, you can download it on the website below.

“I’ve spent an entire day trying to flash openwrt in my new TR1200 without any success. I’ve tried the intermediate image with all openwrt sysupgrade images from most recent down to 24.05.x and in all cases I get the “invalid file” message. What am I missing? f I can’t solve it I’ll have to return the unit.”
