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.

Hello. I have a WR3000S v.1 router (S/N S0007084261201121). I initially installed the transitional firmware `cudy_wr3000s-v1-sysupgrade_20251119.bin` from your website. Currently, I have `openwrt-25.12.5-mediatek-filogic-cudy_wr3000s-v1-squashfs-sysupgrade.bin` installed, with 44 MB of available flash memory. Can I switch to the `openwrt-25.12.5-mediatek-filogic-cudy_wr3000s-v1-ubootmod-squashfs-sysupgrade.itb` firmware to get 90+ MB of memory without risking damage to the router?
Thanks in advance.
Hello Cudy Support,
I have a Cudy WR3000H V1.0.
Serial number: S001004261804085 EU1.0
Current stock firmware: 2.4.5-20250515-105059
I would like to install official OpenWrt. Please send me the latest Cudy-signed OpenWrt intermediate firmware compatible with my WR3000H V1.0.
Thank you!
@Dear Gaetano,
Our technical support has sent you the firmware via email. Please check.
“I have a WR3000 EU 1.0 with s/n: WR3000253209334.
Please can i get the Cudy-signed intermediate firmware in email?”

“Hello,
This is my second attempt to reach you. I wrote to support@cudy.com on 22 May 2026 and never received a reply. I have sent another email today, and I am also posting here since I can see you answer requests in these comments.
Model: WR3000 V1.0
Serial number: WR3000255303583
Current stock firmware: 2.4.19-20250828-192837
Please send me by email the correct Cudy-signed OpenWrt intermediate firmware for this exact unit, and please confirm whether it uses the new F50L1G41LC flash chip or the old one.
I am asking because my SN starts with 2553, which by your own explanation means week 53 of 2025 — later than the 2543 cutoff from your notice of 24 November 2025. However, WR3000 1.0 is not listed among the affected models in that notice, so I do not want to guess which image to use.
Thank you very much."

I would like to install official OpenWrt. I have tried installing the official Cudy “signed” OpenWRT from the google drive link but every time it bricks the router and I have to reflash from TFTP.
Please send me the latest Cudy-signed OpenWrt intermediate firmware compatible with my WR3000 V1.0 and this hardware/flash revision.
