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.

There is no problem with recovery https://github.com/981213/mtk_uartboot I can flash own uboot if neccessary. Please create firmware with signature check removal. I alredy prepare code for testing https://github.com/Linaro1985/openwrt/commit/fec6f44184bba8b8f9534cccb6c30c0da18a0b43
@LINARO
There is no OpenWRT firmware for AP3000 now. We need to wait the OpenWRT forum to release the OpenWRT firmware for AP3000.
“Please, create signature check removal firmware for Cudy AP3000 v1. We planning to use this devices in our offices.”
@NICOLAS
For AP3000, it is because there is no recover feature. If the device is work abnormal. You can’t get it back. For AP1300, there is no Openwrt firmware now. Do you want to develop the Openwrt firmware?
“Hello !
is there a way to have openwrt version for AP1300 ?
have a nice day”
@ZEUS,
For the problem you are facing, upgrading the OpenWRT firmware is useless. What you need is to ask AT&T to apply for a Public IP address for your broadband line.
“I tried to install openwrt on their site with the file and I put it in and it says invalid so I came here to try and flash the remove signature check for the cudy wr3000 and the whole router when blank and refused to reboot so I had to do the emergency flash of the original files. So does this work or not?? I just want openwrt cause I keep getting this message on this software saying “Important note: The router has detected that your current external network IP is not a public network IP” which in short is making my port forwarding stuff not work. I am using this as passthrough with at@t.”
@DOMINIK HERMAN
WR1500 doesn’t support OpenWRT system. So please use other models of Cudy router.
“Could you release firmware file for ax1500 please? Or which we should use for openwrt on ax1500?”
