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 Jerry Z.
The file “TR3000 256MB Flash V1 (not for TR3000 V1)” in the Google Drive is the correct Cudy-signed intermediate firmware. For the model TR3000 256MB Flash V1.0. Only use one model of Flash chip. No such problem as other models.
You can download it via the link below. Please unzip the file and rename it to recovery.bin before recovering.

“Hello Cudy Support,
Device: Cudy TR3000 256MB V1.0
Hardware/region version: ZH 1.0
Serial number: S0002525263701281
Production code: 2637
Flash: F50L1G41LC
Current stock firmware: 2.5.27-20260804-190139
I saw the comments in https://www.cudy.com/blogs/faq/openwrt-software-download and I believe the publicly available intermediate firmware in the Google Drive may not be applicable to this machine.
Please provide:
1. The Cudy-signed OpenWrt intermediate firmware compatible with
TR3000 256MB V1.0, batch 2637 and F50L1G41LC.
2. The matching TFTP recovery.bin for this hardware/region revision.
I found the public intermediate firmware with SHA-256:
702d8a0019f50d81565bf2b7d0eecd1ca4e1720937b1f8340bd4be77c79a2552
Please explicitly confirm whether this exact file is compatible with
batch 2637 / F50L1G41LC.
I will retain the stock BL2, FIP, U-Boot and partition layout."
Hello Cudy Support,
I would like to install official OpenWrt on my router. Please send me the correct Cudy-signed OpenWrt intermediate firmware for my exact unit.
Model: Cudy TR3000-256MB V1.0
Hardware revision: EAEU1.0
Serial number: S0001302262303941
Production week: 2623
Current stock firmware: 2.4.21-20251009-115734
Based on the production date, my unit should have the new F50L1G41LC flash, so I understand the public intermediate firmware from May 2025 is not compatible.
Please send:
1. The Cudy-signed OpenWrt intermediate firmware compatible with this unit (new flash).
2. The matching recovery.bin (TFTP recovery) for this hardware revision, in case I need to restore stock firmware.
After the intermediate firmware, I plan to install the official OpenWrt 25.12.6 sysupgrade image for cudy_tr3000-256mb-v1. Please confirm this is OK.
Thank you!
