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.

Dear Cudy Team
I have not seen an intermediate FW for the “AP1200 Outdoor 1.0” in the google drive link provided. Is it possible to install OpenWRT on this one? (I tried using RE1200, TR1200 and AP1300 but without success)
Thanks
Moritz
@Dear Alex,
Our technical support has contacted you via email. Please check.
“Hello!
Checked and recheched, manual “How to made a brick from Cudy M1800 EU2.0”:
Flash AP with an Openwrt image from page (https://www.cudy.com/en-us/blogs/faq/openwrt-software-download) for example M1800+V2.zip
Update AP with actual Openwrt image (https://firmware-selector.openwrt.org/?version=25.12.6&target=ramips%2Fmt7621&id=cudy_m1800) – sysupgrade
3. All works OK.
Try to recover with official manual (https://www.cudy.com/en-us/blogs/faq/how-to-recovery-the-cudy-router-from-openwrt-firmware-to-cudy-official-firmware) with an image from stage1.
AP reloads with Cudy FW and a error “Invalid board info!”.
Reflash Cudy FW – nothing changed.
Flash openwrt image from stage1 – AP reloaded, but web is not accessible.
Reflash openwrt from stage1 – AP NOT reloaded, led lights slightly, NO UART! GREAT! We got a brick!
Official instruction is bad. Please send me full-flash image to program via flasher or recovery! If it’s needed i can give serials.
Thank you!"

@Dear Deee11,
I suggest you can try to contact the seller to request a replacement. I think it is hardware issue.
“Dear Cudy Support Team,
I need your assistance with installing OpenWrt on my Cudy WR3000H V1.0 router.
Router information:
Model: Cudy WR3000H V1.0 Current stock firmware: 2.5.30-20260825-161645 Current status: Successfully recovered and working on stock firmware Intended firmware: OpenWrt
Description of the problem:
I attempted to install OpenWrt using the intermediate firmware file:
cudy_wr3000h-v1-sysupgrade_20251119.bin
I uploaded this file through the router’s official Cudy web interface. After the installation, the router became unresponsive. The indicator lights remained on, but the Ethernet connection was no longer detected, and I could not access the web administration interface.
I was able to recover the router using TFTP, and it is now working again with the stock firmware version 2.5.30-20260825-161645."
Dear Cudy Support Team,
I need your assistance with installing OpenWrt on my Cudy WR3000H V1.0 router.
Router information:
Model: Cudy WR3000H V1.0 Current stock firmware: 2.5.30-20260825-161645 Current status: Successfully recovered and working on stock firmware Intended firmware: OpenWrtDescription of the problem:
I attempted to install OpenWrt using the intermediate firmware file:
cudy_wr3000h-v1-sysupgrade_20251119.bin
I uploaded this file through the router’s official Cudy web interface. After the installation, the router became unresponsive. The indicator lights remained on, but the Ethernet connection was no longer detected, and I could not access the web administration interface.
I was able to recover the router using TFTP, and it is now working again with the stock firmware version 2.5.30-20260825-161645.
I am concerned that the intermediate firmware may be incompatible with my particular hardware revision or with my current stock firmware version. I would like to avoid bricking the router again.
Could you please help me with the following questions?
1. Is cudy_wr3000h-v1-sysupgrade_20251119.bin compatible with my hardware revision and stock firmware version 2.5.30-20260825-161645?
2. Is there a newer or different Cudy-signed intermediate firmware image that I should use to install OpenWrt safely?
3. Are there different hardware revisions of the WR3000H V1.0 with different flash memory chips or WAN PHY chips that require different firmware images?
4. Is there a way to identify my exact hardware configuration without opening the router?
5. Could you please provide the correct recovery firmware and instructions in case the router becomes unresponsive again?
My goal is to install OpenWrt safely while ensuring compatibility with the router’s hardware.
I would appreciate it if you could provide the correct firmware files and step-by-step installation instructions.
Thank you for your time and support. I look forward to your reply.
Best regards
