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 Cudy Support,
I am trying to install OpenWrt on my WR3000E V1.0 router but encountering an issue.
Device information:
- Model: WR3000E V1.0
- Serial Number: 2549XXXXX (new revision with NAND flash F50L1G41LC, SN ≥ 2543)
- Current firmware: 2.4.19-20250828-192837
Problem:
I downloaded the file “cudy_wr3000e-v1-sysupgrade_20251119.bin” (MD5: 249c150e7676facc9f33d79e634ec4a3) but the router rejects it with “Invalid file” error.
I understand that routers with SN ≥ 2543 require a special intermediary firmware compatible with the new flash chip (post-November 2025). The file dated 2025-11-19 appears to be for older revisions only.
Could you please provide the correct intermediary firmware for WR3000E V1.0 with new flash (SN 2549)?
Thank you for your assistance.
Best regards, Pavel
@Dear ahmed,
You router is WR3000, not WR3000E. I have sent you the correct firmware.

“Dear Cudy Support Team,
I am writing to request the correct intermediate firmware file needed to install OpenWrt on my router.
My router details are:
· Model: Cudy WR3000E
· Hardware Version: v1.0
· Current Firmware Version: 2.2.6-20240902-033948
I have tried several intermediate files, but they were rejected. Could you please provide me with the correct intermediate firmware file compatible with my current firmware version?
Thank you for your assistance.""
Dear CUDY support! Earlier, with your help, I updated my AP3000 v1 to openwrt. Now I need to revert to the factory software. The LUCI web interface complains about an invalid file, and holding down the reset button and supplying power doesn’t work either. Can you help me figure out what to do?
Dear Cudy Support Team,
I desperately need your assistance with my bricked WR3000E router. Here is the complete situation:
Device Details:
Model: Cudy WR3000E
Hardware Version: v1.0
Original Firmware: 2.2.6-20240902-033948
What I have done:
Downloaded official firmware WR3000E-R53-2.4.7-20250528-182254-sysupgrade.zip from your website
Renamed it to recovery.bin and attempted TFTP recovery
The TFTP transfer completed successfully (log attached – 20MB transferred in 9 seconds)
After transfer, the router’s internet LED flashed slowly for over 20 minutes
After power cycling, only the power LED is on
The router responds to ARP and has IP address 192.168.1.112
However:
Cannot access web interface at 192.168.1.112
Cannot connect via SSH or Telnet (connection timed out)
Internet LED does not light up normally
My question:
Is my router recoverable?
Do you have a special recovery tool or different firmware file for units with 128MB flash (if mine is one of those)?
Should I try a different recovery method?
