*/broadcomfail: we should not speak here, open forum thread. Does leds light? For me you just landed in some boot program such like /u-boot/cfe and so on - still you have chance to rescue. Solder goldpins in holes where did you put circle in photo and find serial signals. (http://wiki.openwrt.org/doc/hardware/port.serial)
ok where & where my English is little rusty so take that in mind " open forum thread " HOW
one led blinks for about 10s then no thing

this is all i know
|Version/Model||Launch Date||S/N||OpenWrt Version Supported||Model Specific Notes|
NOTE: Anything not included in model specific notes, or where a short comment couldn't be included on the notes.

|Please include only model specific information, omit bla,bla and put everything generic into separate articles|
|generic.overview if you have no time to write certain stuff link to this|
|basic.config should lead the way, do not explain this again|
|DO NOT provide a complete howto here! Instead groom the general HowTos.|
Please check out the article Flash Layout. It contains an example and a couple of explanations.
|The instructions below are for Broadcom devices and only serve as an example. Don't leave them in place if they do not apply to a particular device!|
This section deals with how you install OpenWrt from a device freshly opened. Plus the steps required such as reset to factory defaults if the device has already been configured
Note: Reset router to factory defaults if it has been previously configured.
|Bootloader tftp server IPv4 address||FILL-IN|
|Bootloader MAC address (special)||FILL-IN|
|Firmware tftp image||Latest OpenWrt release (
|TFTP Transfer Window||FILL-IN seconds|
|TFTP Window Start||approximately FILL-IN seconds after power on|
|TFTP Client Required IP Address||FILL-IN|
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://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc 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:
|Interface Name||Description||Default configuration|
|br-lan||LAN & WiFi||192.168.1.1/24|
|vlan0 (eth0.0)||LAN ports (1 to 4)||None|
|vlan1 (eth0.1)||WAN port||DHCP|
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.

- you could read about bootloader in general
- as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
