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.

Hello,
I requested the intermediate firmware for the TR3000 256MB FLASH V1.0 router with serial number SN: TR3000254700357. You emailed me the firmware file for the 128MB TR3000 V1.0 router. The TR3000 V1_20251118 .zip file is on your Google Drive: https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj?usp=sharing
Or is the intermediate firmware for 128 and 256 routers manufactured after week 47 the same? I need intermediate firmware for the TR3000 router 256MB FLASH V1.0 with serial number SN: TR3000254700357.
@Dear Maxim,
Our technical support has sent you the firmware via email. Please check.
“Hello,
I bought your router:
TR3000 V1.0
SN: TR3000254700357
Firmware Version: 24.21-20251009-115734
Model: TR3000_ZH v1.0
Hardware: TR3000 256MB FLASH V1.0
I want to install OpenWrt on it.
I know that version 128 has a memory chip change and uses a new intermediate firmware. The firmware for version 256 that I found contains an old file from May 21, 2025.
Could you please tell me where I can download the latest firmware for my router version (or the exact name on Google Drive, or please provide a link) and the correct version of OpenWrt so as not to damage the router?
Best regards,
Maxim"

i’ve created a fork of openwrt, added my changes and wrote a post in the openwrt forum:
https://forum.openwrt.org/t/new-device-support-cudy-lt300-v3-0/245463
to go ahead, i now need to install the firmware to figure out the missing peaces
@Dear wespe,
The OpenWrt firmware is not developed by Cudy but by the developers. We need the OpenWrt forum official support the router at first, then we can release a middle firmware for you, then you can use and upgrade to the OpenWrt firmware.
“Hello,
thank you for offering this
please also add for the cudy LT300 3.0
this router looks simular to the LT400 and could be fairly easy to be added to openwrt
thank you”

@Dear Dmitriy,
No, we don’t have the plan to add VLESS function now.
“If OpenWRT is unavailable on the WR3600H, will there be support for VLESS subscription keys in the future?”
