1. → obtain.firmware
2. → Install OpenWrt

Please read flash.layout for some insights.

• Download openwrt-HW553-squashfs-cfe.bin
• Turn on the system while holding the reset for 30 sec.
• connect via LAN with a manual setup of your workstation of 192.168.1.2 etc. (no DHCP, no LAN LED on the box)
• Browse to http://192.168.1.1
• Upload .bin file to router
• Wait for it to reboot (you'll see a red power LED)
• Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 and set the password there…

• Connect the serial TTL cable to send commands to CFE for loading the firmware via tftp.
• Start a TFTP server in your PC. Copy the openwrt-HW553-squashfs-cfe.bin firmware to the server.
• Set the IP at your pc to 192.168.1.35 (or any compatible), and connect the ethernet cable to the router.

This is a session of flashing via TFTP:

→ generic.sysupgrade

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

• 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

• Login as root via SSH on 192.168.1.1
• Use the following commands to upgrade.

cd /tmp/
wget http://downloads.openwrt.org/snapshots/trunk/brcm63xx/openwrt-HW553-squashfs-cfe.bin
sysupgrade /tmp/openwrt-HW553-squashfs-cfe.bin

• If sysupgrade does not support this router, use the following commands.

cd /tmp/
wget http://downloads.openwrt.org/snapshots/trunk/brcm63xx/openwrt-HW553-squashfs-cfe.bin
mtd write /tmp/openwrt-HW553-squashfs-cfe.bin linux && reboot

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

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.

Turn on the device and hold the reset key for 30 sec. http://192.168.1.1 → generic.failsafe

1. you could read about bootloader in general

1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
