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.

“@Dear Cudy team
can you please share Openwrt intermediate Firmware (Cudy signed) for AP3000_P2540 EU v1
Regards!"
@Dear Laci,
Our technical support has sent you the firmware via email. Please check.
“Dear Sir or Madam,
I attempted to download the file X6+V2.zip from the following Google Drive link:
https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj
However, the file was automatically placed into quarantine by my security software because it detected a threat identified as Trojan/Kepavll!rfn.
As a result, I was unable to open or use the file. I wanted to inform you about this issue in case the file needs to be checked, cleaned, or re-uploaded.
Thank you for your assistance.
Kind regards, Laci"
Dear Ilya, Our technical support has sent you the firmware via email. Please check. "Dear Cudy team,
I bought your router:
TR3000_ZH V1.0
SN: TR3000255001964
Firmware Version: 24.21-20251009-115734
Model: TR3000
Hardware: TR3000 256MB FLASH V1.0
I want to install OpenWrt on it.
As I understand it, first an intermediate firmware is installed, and then OpenWrt?
Could you tell me where I can download the intermediate firmware (or the exact name on Google Drive, or please provide a link) and the correct version of OpenWrt, so I don’t brick the router.
Unfortunately, searching online only gives contradictory options, with the risk of turning the router into a brick.
Your tech support (support.ru@cudy.com), as I understand it, is very busy with their own affairs and directs me to search your website instead of providing specific information.
Therefore, I ask for help here. I don’t want to end up with a brick, and I haven’t been able to find clear information.
Thanks in advance."
@Dear tg，
I think you download the wrong file. You router is WR3000, but you downloaded the firmware for WR300. Please download the correct one for WR3000.
“I got wr3000 V1,

Any advice?”
