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 support,
Is it possible to release an OpenWrt firmware for the WR1200 EU V2.0 router? An update for the official firmware removed the ability to set reserved IP addresses in the DHCP config, which is indispensable for various devices (printers, IP cameras, etc.) to work properly.
Best regards,
Paul Nelosi

Dear Rudolf,
Thank you for contacting Cudy support team. The default partition of cudy TR3000 doesn’t fully use all the flash, you can adjust the partition size by yourself.
Domestic kwrt has tutorials and released firmware to resize to larger partitions.
“Hi,
after successfully migrating my TR3000 to OpenWrt I am somewhat confused about
the usable flash size.
The page https://openwrt.org/toh/cudy/tr3000 shows the flash layout of the device.
Summing up all the partitions results in 71.4 MiB. So I miss the difference up to 128 MiB.
The OpenWrt boot log shows:
0.924234] Creating 6 MTD partitions on “spi0.0”:
… kern.notice kernel: [ 0.929038] 0×000000000000-0×000000100000 : “BL2”
… kern.notice kernel: [ 0.934696] 0×000000100000-0×000000180000 : “u-boot-env”
… kern.notice kernel: [ 0.940740] 0×000000180000-0×000000380000 : “Factory”
… kern.notice kernel: [ 0.947440] 0×000000380000-0×0000003c0000 : “bdinfo”
… kern.notice kernel: [ 0.953238] 0×0000003c0000-0×0000005c0000 : “FIP”
… kern.notice kernel: [ 0.959358] 0×0000005c0000-0×0000045c0000 : “ubi”
Calculating these partition sizes results in exactly the same size: 71.4 MiB.
May be my understanding of the flash memory is wrong. Hence would like
if someone could explain the missing MiBs. Many thanks in advance.

Dear Customer，
Thank you for contacting Cudy support team.
The difference between m3000 v1.0 and m3000 v 2.0 is just the colour.
“Hello! What is the difference between m3000 v1.0 and m3000 v 2.0?
Can I use OpenWrt from v.1.0 for version 2.0? Or where can I find OpenWrt for m3000 v 2.0?”
@William,
Dear William,
Do you plan to issue an OpenWRT port for the WR3600H router ? I would like to implement VLANs.——-No, we don’t develop OpenWrt firmware by ourself. All other OpenWrt firmwares are developed by OpenWrt forum. We need to wait other developers to release the OpenWrt firmware.
Second, any chance to enable HTTPS to access the router instead of HTTP? - WR3600H supports HTTPS, please have a try.
Third, could you publish the API for the router, it would be great to integrate in HomeAssistant & Home Bridge. —-We will provide your feedback to the product department for evaluation.
