There are 2 ways to install OpenWrt:
- via an intermediate RSA-signed vendor's image or
- via UART && TFTPd
Migration to OpenWrt via OEM firmware:
- Download the migration image from
https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj
(The folder is Cudy's official "Cudy Intermediary OpenWrt Firmware" resource)
- Upload the migration image via OEM web interface
- After flashing, OpenWrt is accessible via http://192.168.1.1
- Flash the official OpenWrt image
Install using UART & TFTP:
- Connect to UART.
- Connect to LAN and set your IP to 192.168.1.88/24.
- Configure a TFTP server to serve
openwrt-mediatek-filogic-cudy_wr3000u-v1-initramfs-kernel.bin file
and run the TFTP server.
- Press reset and power-on the router. Hold the reset button for 5 seconds
- TFTP error: 'File not found' appears and MTK console becomes available
- Enter the following commands in the console:
setenv bootfile openwrt-mediatek-filogic-cudy_wr3000u-v1-initramfs-kernel.bin
tftpboot
bootm
- After booting to initramfs, via http://192.168.1.1 flash
openwrt-mediatek-filogic-cudy_wr3000u-v1-squashfs-sysupgrade.bin
- After flashing, OpenWrt is accessible via http://192.168.1.1
If you fail to flash the device,
you can use TFTP to flash back to the original firmware:
- Download the original firmware from
https://www.cudy.com/pages/download-center/wr3000u-256mb-1-0
- Connect to LAN and set your IP to 192.168.1.88/24.
Configure a TFTP server and an recovery.bin firmware file
- With the router off, press the RESET button.
While the router is turning on,
the button should continue to be pressed for at least 5 seconds
- After 1-2 minutes the original firmware is available on http://192.168.10.1
