Cudy WR1300 v4

For Developers
61

that's what you've just been told, are you surprised ?

62

I suspect there are minor hardware differences between the v3 and v4 models. I first flashed the device with the Cudy supplied image that was shared via Google Drive, and then force-flashed openwrt-24.10.5-ramips-mt7621-cudy_wr1300-v3-squashfs-sysupgrade.bin

Although the system appears to work correctly, the LEDs are not behaving as expected. The LAN1 and POWER LEDs remain lit all the time, even when I plug a cable into a different port. The other ports function correctly, but their LEDs do not light up. The wifi LEDs also do not behave as expected, although the wireless interfaces appear to be working normally.

63

Oh, great!! Could you please explain in more detail how you installed the firmware on v4, with links to the file? I'm still a complete beginner. Thanks for the help.

64

I got this email from Cuddy:

–

Dear Customer,

Thanks for contacting the Cudy support team. I saw the project. The main difference between V3.0 is the LEDs. So I send you the DTS and GPIO file. May be help for you.

These files from Cuddy are here:

Must say, so grateful for vendor support like this.

65

Is anybody working on trying to get WR1300 v4 into OpenWRT with the updated LED mappings?

66

Not that I know of. If you have the time please go ahead. Thanks.

Hello,
I have submitted a patch adding support for the Cudy WR1300 v4 to the OpenWrt mailing list for review and merging:
https://patchwork.ozlabs.org/project/openwrt/patch/20260512133722.896830-1-jan.brudna@gmail.com/

68

Great, thank you!

69

How long does this process usually take, just wondering as I had a V4 delivered today. Thanks for your work.

70

Thanks! It is hard to say exactly how long the upstreaming process will take. The patch is already on the OpenWrt mailing list and in Patchwork, and I have also sent a v2 after review feedback. From here it depends on maintainer review, so it can be anything from a few days to a few weeks. Once it is merged, WR1300 v4 should eventually appear in snapshot builds and then in the Firmware Selector. (openwrt.org)

If you do not want to wait, you can already build OpenWrt with the current patch yourself.

Build OpenWrt for Cudy WR1300 v4 using the pending patch

sh git clone ``https://git.openwrt.org/openwrt/openwrt.git`` cd openwrt

Download and apply the patch directly from Patchwork:

sh curl -L '``https://patchwork.ozlabs.org/project/openwrt/patch/20260513183938.242137-1-jan.brudna@gmail.com/mbox/``' \ | git am

Patchwork provides patches in mbox form, which can be applied directly with git am. (git-scm.com)

Then configure the build:

sh ./scripts/feeds update -a ./scripts/feeds install -a make menuconfig

Select:

Target System ---> MediaTek Ralink MIPS Subtarget ---> MT7621 based boards Target Profile ---> Cudy WR1300 v4

Then build:

sh make -j$(nproc)

The resulting images should appear under:

text bin/targets/ramips/mt7621/

The sysupgrade image is the one to use when flashing from the Cudy OpenWrt-based firmware.

I have tested the v4 support on real hardware, including:

  • WAN and LAN ports
  • 2.4 GHz and 5 GHz Wi-Fi
  • Reset and WPS button events
  • System, Internet, WAN, LAN1–4 and Wi-Fi LEDs

So anyone with a WR1300 v4 who is comfortable building OpenWrt can already try it before the patch is merged.

If you don't want to build or wait, you could just force flash v3 on, as some have done above in this thread. The LEDs won't work properly, but the rest seems fine. Then when v4 is merged and ready, move to that. I'm considering doing this on my v4, until official v4 is ready.

72

Thanks for all your work and time, much appreciated. I'm not sure how this forum works, should I mark your post as the solution? Seems like it is the final solution.

73

Is there a step-by-step procedure for this, I would hate to brick the router.

I saw a V4 file on the Cudy google drive.

74

From router stock firmware install the v4 image from cudy:

From there, install the latest openwrt v3 image via luci, it will ask you to force the install:

I had stopped short of force install, but other users have force installed and it mostly works (LEDs won't work)

78

First of all, thanks to Aiden. With the patch provided by Aiden, I compiled an OpenWrt firmware myself and have already flashed it onto my router. So far, everything is working normally, and the router’s indicator lights are also functioning properly.

I have uploaded the compiled firmware and the flashing method to GitHub. Anyone interested can give it a try:

79

The cleanest OpenWrt firmware. The installation method is the same as before: you need to flash the original factory firmware first, and then flash this firmware.

80

How does one track the progress on this v4 patch?

Mailing list is here:

Doesn't look like this is going anywhere soon unfortunately.
