Before installation

Distinguishing between Realtek RTL8221B (v1/v2 older) vs Motorcomm YT8821 (v2 newer) variants

How to know if you have the a router with the YT8821 PHY:
 - Boot the router into the vendor's firmware. Go to Diagnostic Tools -> System Log. Try searching for "rtl8221b".
 - If there are some matches, you have the Cudy M3000 router with the Realtek PHY and you should NOT use the device defined in this commit. Instead, you should use the device defined in mt7981b-cudy-m3000-v1.dts.
 - If there are no matches, try searching for "yt8821". If that matches something, you have the Cudy M3000 with the Motorcomm PHY and you should use this device tree (mt7981b-cudy-m3000-v2-yt8821.dts).
 - If even the yt8821 string did not match anything, then something is wrong. Rebooting the router might help (the system log would be refreshed).

Installation instructions

As of Jan 2026, a new variant of M3000 V2 device was shipped with new WAN PHY chip (Motorcomm YT8821 2.5GbE).
This new variant is ONLY supported in version 25.12.1 and Main Snapshot branch by incorporating commits to include the kmod-phy-motorcomm driver.

If you own this new variant, you should flash the v2 (yt8821 new variant) image instead. See more info in GitHub PR# 22259 & PR# 22423.

FIXME Please add the installation procedure here. For now, check out Supported Since Commit field in the above table for basic flash instructions.

See OEM easy installation for a guide on how to install OpenWrt after unboxing the device

Upgrading OpenWrt

→ generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

LuCI Web Upgrade Process

  • Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

Terminal Upgrade Process

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Flash Layout

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

Debricking

Specific Configuration

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Network interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP
wl0 EXAMPLE WiFi EXAMPLE Disabled

Switch Ports (for VLANs)

FIXME Please fill in real values for this device, then remove the EXAMPLEs

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
