Installation
------------
1. Run tftp server on your PC (IP: 192.168.2.2) and put OpenWrt initramfs
image (initramfs.bin) to the tftp root dir
2. Open the following link in the browser to enable telnet:
http://192.168.2.1/cgi-bin/telnet_ssh
3. Connect to the router (default IP: 192.168.2.1) using telnet shell
(credentials - user:admin)
4. Run the following commands in the telnet shell (this will install
OpenWrt initramfs image on nand flash):
cd /tmp
tftp -g -r initramfs.bin 192.168.2.2
mtd write initramfs.bin firmware
mtd erase firmware_backup
reboot
5. Copy OpenWrt sysupgrade image (sysupgrade.bin) to the /tmp dir of the
router
6. Connect to the router (IP: 192.168.1.1) using ssh shell and run
sysupgrade command:
sysupgrade -n /tmp/sysupgrade.bin
Return to stock
---------------
1. Copy stock firmware (stock.bin) to the /tmp dir of the router using scp
2. Run following command in the router shell:
cd /tmp
mtd write stock.bin firmware
reboot
Recovery
--------
Connect uart (pins are silkscreened on the pcb), interrupt boot process by
pressing any key, use u-boot menu to flash stock firmware image or OpenWrt
initramfs image.
MAC addresses

The WLAN 2.4 MAC was found in 'factory', 0x4
The LAN MAC was found in 'factory', 0xfff4
The WAN MAC was found in 'factory', 0xfffa
Note: This device is similar to Z-ROUTER ZR-2660, but with minor hardware
revisions. The firmware and configuration are compatible.
